KotlinCompose MultiplatformNavigation 3DIAuthSync

📝 Material Notes is a clean, Material 3 note-taking app built with Compose Multiplatform — running on Android, iOS, and Desktop from a single shared, multi-module codebase, with Navigation 3, SQLDelight, Metro DI, Coroutines, Flow, email/Google/Apple sign-in and per-user cloud sync via a Supabase KMP SDK, and a card-to-detail shared-element transition based on MVVM architecture.

Material Notes demo

Tip

The same Compose UI and logic run natively on Android, iOS, and Desktop (JVM) — split across :core and :feature Kotlin Multiplatform modules.

Running

  • Android — ./gradlew :composeApp:assembleDebug, or run the composeApp configuration in Android Studio.
  • Desktop — ./gradlew :composeApp:run
  • iOS — open iosApp/iosApp.xcodeproj in Xcode, set your signing TEAM_ID in iosApp/Configuration/Config.xcconfig, pick a simulator, and run. The "Compile Kotlin Framework" build phase invokes Gradle to build the shared framework.

Tech stack & Open-source libraries

  • Minimum SDK level 24 · targets Android, iOS, and Desktop (JVM).
  • Kotlin based, with Coroutines and Flow for async streams.
  • Compose Multiplatform Libraries:
    • Compose Multiplatform — declarative UI + Material 3.
    • Lifecycle & ViewModel — org.jetbrains.androidx.lifecycle (multiplatform).
    • Navigation 3 — NavDisplay + entryProvider with type-safe NavKey routes and entry-scoped ViewModels (org.jetbrains.androidx.navigation3).
    • SQLDelight — typesafe SQL with platform drivers (Android / native / JDBC).
  • Supabase KMP SDK — io.github.androidpoet:supabase-* — email/Google/Apple auth (supabase-auth) plus per-user two-way cloud note sync (push + pull), offline-first.
  • Metro — compile-time dependency injection (a Kotlin compiler plugin), wired across modules.
  • Architecture:
    • MVVM Architecture (View → ViewModel → Repository → SQLDelight queries).
    • Repository Pattern.
    • Multi-module: :core:data, :core:designsystem, :feature:*, :composeApp.
  • kotlinx-datetime — multiplatform date/time formatting.
  • Shared-element transition — SharedTransitionLayout + sharedBounds morph the note card into the detail screen (the AnimatedVisibilityScope comes from Nav3's LocalNavAnimatedContentScope).

Architecture

Material Notes follows MVVM across a multi-module Kotlin Multiplatform setup. Each module targets Android, Desktop (JVM), and iOS; the app shell assembles them and the Metro graph wires dependencies across module boundaries at compile time.

:composeApp # App shell: App, AppNavHost (Nav3), Metro AppGraph, platform entry points
:core:data # Note, MainRepository, SQLDelight schema + drivers (Android / native / JDBC)
:core:designsystem # Theme, palette, icons, shared-element helpers, date util
:feature:auth # AuthScreen (login / sign-up) + AuthViewModel
:feature:home # HomeScreen + NotesViewModel
:feature:addnote # AddNoteScreen + AddNoteViewModel
:feature:detail # NoteDetailScreen + NoteDetailViewModel
iosApp/ # Xcode project (SwiftUI shell hosting the Compose UI)

Dependencies flow one way — :composeApp → :feature:* → :core:* — so the graph stays acyclic. Feature screens receive their ViewModel as a parameter; AppNavHost (which can see both the Metro graph and the screens) creates each entry-scoped ViewModel and passes it down. Each platform supplies a SQLDelight SqlDriver (:core:data/.../DatabaseDriver.*.kt) into buildAppGraph(driver, ioDispatcher). Because Metro validates the graph at compile time, a wiring mistake fails the build instead of crashing at runtime.

Auth + cloud sync (Supabase) — live demo

This repo ships pointed at a real, live Supabase project, so you can clone, run, sign up, and watch your notes sync against the cloud with zero setup. It's a working showcase of AndroidPoet's Supabase KMP SDK end-to-end.

Sign in. On launch the app shows a login screen (:feature:auth). Create an account or sign in with email + password — handled by supabase-auth via AuthService. Google (Android) and Apple (iOS/macOS) buttons are wired in and light up once their OAuth providers are enabled on the project.

Per-user sync. Notes live locally in SQLDelight and the app is fully usable offline. The Sync button in the home header does an explicit two-way sync: it upserts every local note up to the Supabase notes table, then pulls the table back down — so a note saved on any device converges everywhere. Both directions are paged (batched upserts; a count-aware selectWithCount + PostgREST range walk on the pull) so the sync scales to a large notebook. Every request carries the signed-in user's JWT, and a user_id column + Row Level Security scope every row to its owner, so each account sees only its own notebook.

Security. The app uses only the project URL and the public anon key — designed to ship in clients and constrained entirely by RLS (see supabase/schema.sql). The service_role key bypasses RLS and is never used in the client. Credentials are kept out of source control: they are read at build time from local.properties (or SUPABASE_URL / SUPABASE_ANON_KEY env vars) into a generated SupabaseSecrets (see core/data/build.gradle.kts). To run against your own project, add to local.properties:

supabase.url=https://YOUR-REF.supabase.co
supabase.anonKey=YOUR-ANON-KEY

and apply the schema with supabase db push (or paste supabase/schema.sql into the SQL Editor). Leave them unset and the app simply runs offline.

Note

Auth lives in :core:data under .../data/auth/ (AuthService, SessionStore, SocialAuthService) and the sync in .../data/sync/ (SupabaseConfig, SupabaseProvider, RemoteNote, NoteSyncService). A single auth-aware SupabaseProvider client feeds both, wired via Metro; the SessionStore flow gates navigation between the login screen and the notes app.

Version matrix

Kotlin 2.4.0 · Compose Multiplatform 1.11.1 · Navigation 3 1.1.0 · AGP 8.11.1 · SQLDelight 2.3.2 · Metro 1.2.0 · Supabase KMP 0.6.0 · Lifecycle (JB) 2.10.0 · Gradle 8.14 · JDK 21 (see gradle/libs.versions.toml).

Note

Toolchain notes. The Supabase KMP SDK 0.6.0 is built with Kotlin 2.4.0, so the app tracks the same toolchain: Kotlin 2.4.0 with Metro 1.2.0 (its Gradle plugin pins the Kotlin plugin to 2.4.x) and Compose Multiplatform 1.11.1. Metro requires JDK 21 + Gradle 8.13+ — gradle/gradle-daemon-jvm.properties selects the JDK 21 toolchain automatically. On iOS, SQLDelight's native driver (SQLiter) needs the app to link -lsqlite3 (in OTHER_LDFLAGS), and CADisableMinimumFrameDurationOnPhone=true must be set in iosApp/iosApp/Info.plist. material-icons-extended is no longer published for CMP 1.8+, so the few icons used are hand-authored ImageVectors.

📝 Material Notes is a clean, Material 3 note-taking app built with Compose Multiplatform — running on Android, iOS, and Desktop from a single shared, multi-module codebase, with Navigation 3, SQLDelight, Metro DI, Coroutines, Flow, email/Google/Apple sign-in and per-user cloud sync via a Supabase KMP SDK, and a card-to-detail shared-element transition based on MVVM architecture.

Material Notes demo
Tip
The same Compose UI and logic run natively on Android, iOS, and Desktop (JVM) — split across :core and :feature Kotlin Multiplatform modules.
Running
  • Android — ./gradlew :composeApp:assembleDebug, or run the composeApp configuration in Android Studio.
  • Desktop — ./gradlew :composeApp:run
  • iOS — open iosApp/iosApp.xcodeproj in Xcode, set your signing TEAM_ID in
iosApp/Configuration/Config.xcconfig, pick a simulator, and run. The "Compile Kotlin Framework"
build phase invokes Gradle to build the shared framework.
Tech stack & Open-source libraries
  • Minimum SDK level 24 · targets Android, iOS, and Desktop (JVM).
  • Kotlin based, with Coroutines and Flow for async streams.
  • Compose Multiplatform Libraries:

    • Compose Multiplatform — declarative UI + Material 3.
    • Lifecycle & ViewModel — org.jetbrains.androidx.lifecycle (multiplatform).
    • Navigation 3 — NavDisplay + entryProvider with type-safe NavKey routes and entry-scoped ViewModels (org.jetbrains.androidx.navigation3).
    • SQLDelight — typesafe SQL with platform drivers (Android / native / JDBC).
  • Supabase KMP SDK — io.github.androidpoet:supabase-* — email/Google/Apple auth (supabase-auth) plus per-user two-way cloud note sync (push + pull), offline-first.
  • Metro — compile-time dependency injection (a Kotlin compiler plugin), wired across modules.
  • Architecture:

    • MVVM Architecture (View → ViewModel → Repository → SQLDelight queries).
    • Repository Pattern.
    • Multi-module: :core:data, :core:designsystem, :feature:*, :composeApp.
  • kotlinx-datetime — multiplatform date/time formatting.
  • Shared-element transition — SharedTransitionLayout + sharedBounds morph the note card into the detail screen (the AnimatedVisibilityScope comes from Nav3's LocalNavAnimatedContentScope).
Architecture
Material Notes follows MVVM across a multi-module Kotlin Multiplatform setup. Each module targets
Android, Desktop (JVM), and iOS; the app shell assembles them and the Metro graph wires dependencies
across module boundaries at compile time.
:composeApp # App shell: App, AppNavHost (Nav3), Metro AppGraph, platform entry points
:core:data # Note, MainRepository, SQLDelight schema + drivers (Android / native / JDBC)
:core:designsystem # Theme, palette, icons, shared-element helpers, date util
:feature:auth # AuthScreen (login / sign-up) + AuthViewModel
:feature:home # HomeScreen + NotesViewModel
:feature:addnote # AddNoteScreen + AddNoteViewModel
:feature:detail # NoteDetailScreen + NoteDetailViewModel
iosApp/ # Xcode project (SwiftUI shell hosting the Compose UI)

Dependencies flow one way — :composeApp → :feature:* → :core:* — so the graph stays acyclic. Feature
screens receive their ViewModel as a parameter; AppNavHost (which can see both the Metro graph and the
screens) creates each entry-scoped ViewModel and passes it down. Each platform supplies a SQLDelight
SqlDriver (:core:data/.../DatabaseDriver.*.kt) into buildAppGraph(driver, ioDispatcher). Because Metro
validates the graph at compile time, a wiring mistake fails the build instead of crashing at runtime.
Auth + cloud sync (Supabase) — live demo
This repo ships pointed at a real, live Supabase project, so you can clone, run, sign up, and watch
your notes sync against the cloud with zero setup. It's a working showcase of AndroidPoet's Supabase KMP
SDK end-to-end.
Sign in. On launch the app shows a login screen (:feature:auth). Create an account or sign in with
email + password — handled by supabase-auth via AuthService. Google (Android) and Apple
(iOS/macOS) buttons are wired in and light up once their OAuth providers are enabled on the project.
Per-user sync. Notes live locally in SQLDelight and the app is fully usable offline. The Sync
button in the home header does an explicit two-way sync: it upserts every local note up to the Supabase
notes table, then pulls the table back down — so a note saved on any device converges everywhere. Both
directions are paged (batched upserts; a count-aware selectWithCount + PostgREST range walk on the
pull) so the sync scales to a large notebook. Every request carries the signed-in user's JWT, and a
user_id column + Row Level Security scope every row to its owner, so each account sees only its own notebook.
Security. The app uses only the project URL and the public anon key — designed to ship in clients
and constrained entirely by RLS (see supabase/schema.sql). The service_role key
bypasses RLS and is never used in the client. Credentials are kept out of source control: they are
read at build time from local.properties (or SUPABASE_URL / SUPABASE_ANON_KEY env vars) into a
generated SupabaseSecrets (see core/data/build.gradle.kts). To run against your own project, add to
local.properties:
supabase.url=https://YOUR-REF.supabase.co
supabase.anonKey=YOUR-ANON-KEY
and apply the schema with supabase db push (or paste supabase/schema.sql into the
SQL Editor). Leave them unset and the app simply runs offline.
Note
Auth lives in :core:data under .../data/auth/ (AuthService, SessionStore, SocialAuthService)
and the sync in .../data/sync/ (SupabaseConfig, SupabaseProvider, RemoteNote, NoteSyncService).
A single auth-aware SupabaseProvider client feeds both, wired via Metro; the SessionStore flow gates
navigation between the login screen and the notes app.
Version matrix
Kotlin 2.4.0 · Compose Multiplatform 1.11.1 · Navigation 3 1.1.0 · AGP 8.11.1 · SQLDelight 2.3.2 ·
Metro 1.2.0 · Supabase KMP 0.6.0 · Lifecycle (JB) 2.10.0 · Gradle 8.14 · JDK 21 (see gradle/libs.versions.toml).
Note
Toolchain notes. The Supabase KMP SDK 0.6.0 is built with Kotlin 2.4.0, so the app tracks the same
toolchain: Kotlin 2.4.0 with Metro 1.2.0 (its Gradle plugin pins the Kotlin plugin to 2.4.x) and
Compose Multiplatform 1.11.1. Metro requires JDK 21 + Gradle 8.13+ — gradle/gradle-daemon-jvm.properties
selects the JDK 21 toolchain automatically. On iOS, SQLDelight's native driver (SQLiter) needs the app to link -lsqlite3
(in OTHER_LDFLAGS), and CADisableMinimumFrameDurationOnPhone=true must be set in
iosApp/iosApp/Info.plist. material-icons-extended is no longer published for CMP 1.8+, so the few
icons used are hand-authored ImageVectors.

KotlinCompose MultiplatformNavigation 3DIAuthSync

📝 Material Notes is a clean, Material 3 note-taking app built with Compose Multiplatform — running on Android, iOS, and Desktop from a single shared, multi-module codebase, with Navigation 3, SQLDelight, Metro DI, Coroutines, Flow, email/Google/Apple sign-in and per-user cloud sync via a Supabase KMP SDK, and a card-to-detail shared-element transition based on MVVM architecture.

Material Notes demo
Tip
The same Compose UI and logic run natively on Android, iOS, and Desktop (JVM) — split across :core and :feature Kotlin Multiplatform modules.
Running
  • Android — ./gradlew :composeApp:assembleDebug, or run the composeApp configuration in Android Studio.
  • Desktop — ./gradlew :composeApp:run
  • iOS — open iosApp/iosApp.xcodeproj in Xcode, set your signing TEAM_ID in
iosApp/Configuration/Config.xcconfig, pick a simulator, and run. The "Compile Kotlin Framework"
build phase invokes Gradle to build the shared framework.
Tech stack & Open-source libraries
  • Minimum SDK level 24 · targets Android, iOS, and Desktop (JVM).
  • Kotlin based, with Coroutines and Flow for async streams.
  • Compose Multiplatform Libraries:

Architecture
Material Notes follows MVVM across a multi-module Kotlin Multiplatform setup. Each module targets
Android, Desktop (JVM), and iOS; the app shell assembles them and the Metro graph wires dependencies
across module boundaries at compile time.
:composeApp # App shell: App, AppNavHost (Nav3), Metro AppGraph, platform entry points
:core:data # Note, MainRepository, SQLDelight schema + drivers (Android / native / JDBC)
:core:designsystem # Theme, palette, icons, shared-element helpers, date util
:feature:auth # AuthScreen (login / sign-up) + AuthViewModel
:feature:home # HomeScreen + NotesViewModel
:feature:addnote # AddNoteScreen + AddNoteViewModel
:feature:detail # NoteDetailScreen + NoteDetailViewModel
iosApp/ # Xcode project (SwiftUI shell hosting the Compose UI)

Dependencies flow one way — :composeApp → :feature:* → :core:* — so the graph stays acyclic. Feature
screens receive their ViewModel as a parameter; AppNavHost (which can see both the Metro graph and the
screens) creates each entry-scoped ViewModel and passes it down. Each platform supplies a SQLDelight
SqlDriver (:core:data/.../DatabaseDriver.*.kt) into buildAppGraph(driver, ioDispatcher). Because Metro
validates the graph at compile time, a wiring mistake fails the build instead of crashing at runtime.
Auth + cloud sync (Supabase) — live demo
This repo ships pointed at a real, live Supabase project, so you can clone, run, sign up, and watch
your notes sync against the cloud with zero setup. It's a working showcase of AndroidPoet's Supabase KMP
SDK end-to-end.
Sign in. On launch the app shows a login screen (:feature:auth). Create an account or sign in with
email + password — handled by supabase-auth via AuthService. Google (Android) and Apple
(iOS/macOS) buttons are wired in and light up once their OAuth providers are enabled on the project.
Per-user sync. Notes live locally in SQLDelight and the app is fully usable offline. The Sync
button in the home header does an explicit two-way sync: it upserts every local note up to the Supabase
notes table, then pulls the table back down — so a note saved on any device converges everywhere. Both
directions are paged (batched upserts; a count-aware selectWithCount + PostgREST range walk on the
pull) so the sync scales to a large notebook. Every request carries the signed-in user's JWT, and a
user_id column + Row Level Security scope every row to its owner, so each account sees only its own notebook.
Security. The app uses only the project URL and the public anon key — designed to ship in clients
and constrained entirely by RLS (see supabase/schema.sql). The service_role key
bypasses RLS and is never used in the client. Credentials are kept out of source control: they are
read at build time from local.properties (or SUPABASE_URL / SUPABASE_ANON_KEY env vars) into a
generated SupabaseSecrets (see core/data/build.gradle.kts). To run against your own project, add to
local.properties:
supabase.url=https://YOUR-REF.supabase.co
supabase.anonKey=YOUR-ANON-KEY
and apply the schema with supabase db push (or paste supabase/schema.sql into the
SQL Editor). Leave them unset and the app simply runs offline.
Note
Auth lives in :core:data under .../data/auth/ (AuthService, SessionStore, SocialAuthService)
and the sync in .../data/sync/ (SupabaseConfig, SupabaseProvider, RemoteNote, NoteSyncService).
A single auth-aware SupabaseProvider client feeds both, wired via Metro; the SessionStore flow gates
navigation between the login screen and the notes app.
Version matrix
Kotlin 2.4.0 · Compose Multiplatform 1.11.1 · Navigation 3 1.1.0 · AGP 8.11.1 · SQLDelight 2.3.2 ·
Metro 1.2.0 · Supabase KMP 0.6.0 · Lifecycle (JB) 2.10.0 · Gradle 8.14 · JDK 21 (see gradle/libs.versions.toml).
Note
Toolchain notes. The Supabase KMP SDK 0.6.0 is built with Kotlin 2.4.0, so the app tracks the same
toolchain: Kotlin 2.4.0 with Metro 1.2.0 (its Gradle plugin pins the Kotlin plugin to 2.4.x) and
Compose Multiplatform 1.11.1. Metro requires JDK 21 + Gradle 8.13+ — gradle/gradle-daemon-jvm.properties
selects the JDK 21 toolchain automatically. On iOS, SQLDelight's native driver (SQLiter) needs the app to link -lsqlite3
(in OTHER_LDFLAGS), and CADisableMinimumFrameDurationOnPhone=true must be set in
iosApp/iosApp/Info.plist. material-icons-extended is no longer published for CMP 1.8+, so the few
icons used are hand-authored ImageVectors.

KotlinCompose MultiplatformNavigation 3DIAuthSync

📝 Material Notes is a clean, Material 3 note-taking app built with Compose Multiplatform — running on Android, iOS, and Desktop from a single shared, multi-module codebase, with Navigation 3, SQLDelight, Metro DI, Coroutines, Flow, email/Google/Apple sign-in and per-user cloud sync via a Supabase KMP SDK, and a card-to-detail shared-element transition based on MVVM architecture.

Material Notes demo
Tip
The same Compose UI and logic run natively on Android, iOS, and Desktop (JVM) — split across :core and :feature Kotlin Multiplatform modules.
Running
  • Android — ./gradlew :composeApp:assembleDebug, or run the composeApp configuration in Android Studio.
  • Desktop — ./gradlew :composeApp:run
  • iOS — open iosApp/iosApp.xcodeproj in Xcode, set your signing TEAM_ID in
iosApp/Configuration/Config.xcconfig, pick a simulator, and run. The "Compile Kotlin Framework"
build phase invokes Gradle to build the shared framework.
Tech stack & Open-source libraries
  • Minimum SDK level 24 · targets Android, iOS, and Desktop (JVM).
  • Kotlin based, with Coroutines and Flow for async streams.
  • Compose Multiplatform Libraries:

    • Compose Multiplatform — declarative UI + Material 3.
    • Lifecycle & ViewModel — org.jetbrains.androidx.lifecycle (multiplatform).
    • Navigation 3 — NavDisplay + entryProvider with type-safe NavKey routes and entry-scoped ViewModels (org.jetbrains.androidx.navigation3).
    • SQLDelight — typesafe SQL with platform drivers (Android / native / JDBC).
  • Supabase KMP SDK — io.github.androidpoet:supabase-* — email/Google/Apple auth (supabase-auth) plus per-user two-way cloud note sync (push + pull), offline-first.
  • Metro — compile-time dependency injection (a Kotlin compiler plugin), wired across modules.
  • Architecture:

    • MVVM Architecture (View → ViewModel → Repository → SQLDelight queries).
    • Repository Pattern.
    • Multi-module: :core:data, :core:designsystem, :feature:*, :composeApp.
  • kotlinx-datetime — multiplatform date/time formatting.
  • Shared-element transition — SharedTransitionLayout + sharedBounds morph the note card into the detail screen (the AnimatedVisibilityScope comes from Nav3's LocalNavAnimatedContentScope).

:feature:home # HomeScreen + NotesViewModel
