Flutter build apk --split-debug-info output location documentation

💡 Result:

When running a Flutter build with the --split-debug-info flag, the output location for debug symbols is determined by the directory path you explicitly provide as an argument to the flag [1][2]. The flag syntax is: flutter build --split-debug-info=/ [1][2] Key details regarding the output location: - User-Defined Path: You specify the directory path where Flutter should save the symbol files [1][2]. For example, using --split-debug-info=out/android will create a directory named out/android (relative to your project root) and place the generated symbol files there [3][2]. - Not Automatic: Flutter does not place these symbols in a default build folder unless you explicitly direct it to do so (e.g., --split-debug-info=build/app/outputs/symbols) [3]. - Purpose: This command generates symbol map files (e.g., app.android-arm.symbols), which are essential for de-obfuscating stack traces from crash reports [1][4][5]. - Persistence: It is recommended to store these symbols outside of ephemeral build directories (like the standard build/ folder), as they may be cleared by a flutter clean command [4]. Developers often commit these files to version control or an external symbol storage service to ensure they are available for future debugging sessions [4].

subosito flutter-action flutter analyze test cache true outputs CACHE-HIT

💡 Result:

The subosito/flutter-action GitHub Action provides CACHE-HIT and PUB-CACHE-HIT outputs that allow you to determine whether the Flutter SDK or pub dependencies were successfully retrieved from the cache [1][2][3]. These outputs are available starting from version v2.21.0 [2]. They directly reflect the cache-hit output from the underlying actions/cache steps [4][5][3]. Key details regarding these outputs: - CACHE-HIT: Indicates whether the Flutter SDK cache was a hit [1][3]. - PUB-CACHE-HIT: Indicates whether the pub dependencies cache was a hit [1][3]. - Behavior: These outputs return 'true' if there is an exact match for the cache key, and an empty string if there is a cache miss [4][6][5]. Example usage: You can use these outputs to conditionally execute steps in your workflow, such as skipping dependency installation when a cache hit occurs [7][3]: steps: - name: Set up Flutter uses: subosito/flutter-action@v2 id: flutter-action with: channel: stable cache: true - name: Conditionally run dependencies installation if: steps.flutter-action.outputs.PUB-CACHE-HIT!= 'true' run: flutter pub get - name: Continue with build run: flutter build apk Note that you must provide an id to the flutter-action step (e.g., id: flutter-action) to reference these outputs in subsequent steps [7][3].

🌐 Web query:

site:github.com/subosito/flutter-action action.yaml CACHE-HIT PUB-CACHE-HIT cache

💡 Result:

In the context of the subosito/flutter-action GitHub Action, CACHE-HIT and PUB-CACHE-HIT are output variables that provide information about the status of the Flutter SDK and Dart pub dependencies caches, respectively [1][2]. These outputs are defined in the action's configuration (action.yaml) to allow users to conditionally execute steps based on whether a cache was restored successfully [1][2]. Specifically: CACHE-HIT: Indicates whether the Flutter SDK cache was a hit (returns 'true' if there is an exact match for the cache key) [1]. PUB-CACHE-HIT: Indicates whether the Dart pub dependencies cache was a hit (returns 'true' if there is an exact match for the cache key) [1]. These values are sourced directly from the cache-hit output of the underlying actions/cache step used within the action [3][4]. They are commonly used in workflow YAML files to skip redundant installation or setup steps, such as bootstrapping dependencies, when a valid cache already exists [2][5]. Example usage in a workflow: - name: Set up Flutter uses: subosito/flutter-action@v2 id: flutter-action with: cache: true pub-cache: true - name: Conditionally run setup if: steps.flutter-action.outputs.PUB-CACHE-HIT!= 'true' run: dart pub get

Citations:


🌐 Web query:

site:docs.dart.dev packages flutter test analyze package_config.json pub cache

💡 Result:

Relevant official Dart/Flutter documentation:

  • Packages: use pubspec.yaml and dart pub get to resolve dependencies. [1]
  • Flutter package commands: use flutter pub, flutter analyze, and flutter test; Flutter recommends these instead of the equivalent Dart commands in Flutter projects. [2]
  • Static analysis:dart analyze [DIRECTORY|FILE] analyzes Dart source code. [3]
  • Testing: Flutter tests typically live under test/; run them with flutter test. [4]
  • package_config.json: Pub generates .dart_tool/package_config.json, mapping package names to their locations; workspaces use one shared file. [5]
  • Pub cache: recent Dart versions include dart pub cache gc to remove packages no longer referenced by current projects. [6]

The original query returned no exact docs.dart.dev match; current documentation is primarily on dart.dev and docs.flutter.dev.


Run dependency resolution when the Flutter SDK cache hits.

CACHE-HIT reports whether the Flutter SDK cache was restored. This skips flutter pub get even when the project pub cache was not restored, leaving .dart_tool/package_config.json unresolved for flutter analyze and flutter test. Check steps.flutter-action.outputs.PUB-CACHE-HIT instead, or always run flutter pub get for clean runners.

# Hive → SQLite Migration + Coach SQL Query Tool — Design Spec

**Date:** 2026-08-08
**Status:** Approved
**Feature area:** Storage layer (`lib/services/`) + AI Coach tools (`lib/services/ai/`)

---

## 1. Problem

The AI Coach (`CoachToolService`) currently exposes ~15 narrow, purpose-built tools (`get_exercise_performance`, `get_workouts_in_range`, etc.), each hand-wrapping a specific `WorkoutProvider`/`PRManager` query. This is fine for known question shapes but can't answer arbitrary analytical questions the model wasn't given a preset tool for (e.g. ad-hoc joins, unusual aggregations, novel filters).

The fix — a generic SQL query tool — is a poor fit for the current storage layer: RepForge persists to **Hive**, a key-value store with no query language. Any SQL tool would need a translation layer.

Two paths were considered:
- **Ephemeral snapshot**: build a throwaway in-memory SQLite mirror on every coach tool call, rebuilt from Hive-backed in-memory lists each time.
- **Real migration**: replace Hive with SQLite as the actual persistence backend, so the coach's SQL tool queries live data directly with no translation step.

This spec chooses the second path. `IStorageService` (`lib/services/interfaces/storage_service_interface.dart`) is already a clean DIP boundary — every method takes/returns plain Dart models, no Hive types leak through — so a `SqliteStorageService implements IStorageService` swap is architecturally sound without touching any manager, `WorkoutProvider`, or screen. `MockStorageService` already fulfills the same interface, so the existing test suite is unaffected by the backend swap.

This is two dependent efforts: (A) migrate the storage backend, (B) add the coach's SQL tool on top of it. (A) is materially riskier — it touches real user data — and is the majority of this spec.

---

## 2. Goal

1. Replace Hive with SQLite (`sqflite`) as RepForge's persistence backend, via a new `SqliteStorageService implements IStorageService`, with a safe, reversible, one-time migration for existing installs.
2. Add `run_sql_query` to `CoachToolService`: the model submits a read-only SQL `SELECT`, executed against a dedicated read-only connection to the live database, results returned as JSON rows.

Non-goals: no UI changes, no new user-facing features, no change to any existing `IStorageService` method signature or manager/provider code.

---

## 3. Package Choice: `sqflite`

Considered `sqlite3` (FFI, synchronous) vs `sqflite` (platform channel, async). Chose **`sqflite`**:

- `IStorageService` is entirely `Future`-based already. `sqflite` runs DB work on a native background thread and returns via `Future` naturally — no extra isolate-management code. `sqlite3` is synchronous on the calling isolate; matching the same non-blocking behavior would require hand-rolling a background isolate, which is unjustified complexity at this app's data scale.
- `sqflite` supports `rawQuery(sql, args)` / `rawInsert` / `rawUpdate`, so the coach's arbitrary-SQL tool works identically to how it would under `sqlite3`. No capability is lost.
- No native binary bundling (`sqlite3_flutter_libs`) needed; uses the OS-provided SQLite.

**Known tradeoff:** `sqflite` uses the Android-bundled SQLite version rather than a pinned one, so very old devices could lack newer SQL features (e.g. window functions, SQLite 3.25+/Android 9+). Accepted as low risk for this app's scale and audience.

**Test dependency:** add `sqflite_common_ffi` (dev dependency) — required to run `sqflite`-backed code under `flutter test`, since plain `sqflite` needs a real platform binding unavailable off-device.

---

## 4. Schema

All tables live in one SQLite database file, created in `onCreate`.

```sql
CREATE TABLE exercises (
id TEXT PRIMARY KEY,
name TEXT NOT NULL,
category TEXT NOT NULL, -- 'compound' | 'isolation'
is_custom INTEGER NOT NULL DEFAULT 0,

Enforce and declare all foreign keys.

Configure PRAGMA foreign_keys = ON in openDatabase’s onConfigure callback. SQLite disables enforcement by default and applies it per connection, so onCreate alone is insufficient. Add a test that rejects an invalid child insert.

Add REFERENCES muscle_groups(id) to exercise_muscle_activations.muscle_group_id; otherwise orphan muscle-group references remain possible.

Preserve handle-scoped personal records.

personal_records uses only exercise_id as its primary key. The current release adds handle-specific records. SQLite cannot store separate records for multiple handles of the same exercise with this key, so migration will collapse or overwrite records. Add the handle dimension to the schema and key, then test two records for the same exercise with different handles.

Exclude secrets from run_sql_query.

The schema exposes settings(key, value), and the app stores the user-supplied Gemini API key in Settings. Because the tool accepts arbitrary SELECT statements, the model can query and return that key. Exclude settings and other secret columns, or expose only an allowlisted set of read-only views.

**Deliberately not fully normalized:** `training_programs` (phases/weeks/days/exercises) and `conversations` (messages) are stored as JSON-blob columns rather than exploded into child tables. Both are always read/written as a whole object via existing `toJson()`/`fromJson()` methods, never queried piecemeal by any manager or by the coach's SQL tool. Normalizing them would add several more tables for no query benefit — YAGNI.

## 5. `SqliteStorageService`

New file: `lib/services/sqlite_storage_service.dart`, `class SqliteStorageService implements IStorageService`.

- `init()`: opens the database (`openDatabase`), runs `onCreate` (schema above) on first creation.
- Every `IStorageService` method gets a real implementation: entity writes that touch multiple tables (e.g. `saveWorkoutSession` → `sessions` + `exercise_logs` + `sets`) run inside a single `db.transaction()` — delete-then-reinsert child rows for the given parent id, so updates and inserts share one code path.
- `exportAllData()` / `importData()` keep their existing JSON contract (used by the migration below and by the user-facing export/import feature) — implemented by reading/writing through the same model `toJson()`/`fromJson()` methods already used elsewhere.

No changes to `IStorageService`'s method signatures.

---

## 6. Migration & Cutover

**Goal:** existing installs upgrade from Hive to SQLite exactly once, safely, with no possibility of a half-migrated state.

1. On app start, `AppInitializer` (in `main.dart`) checks `settings['storage_migrated_v1']` **in the existing Hive settings box** (the migration hasn't happened yet at this point, so Hive is still authoritative for this check).
2. If unset: instantiate both the existing `StorageService` (Hive) and a fresh `SqliteStorageService`. For every entity type, read via the existing, already-correct Hive read methods (`getAllWorkoutSessions()`, `getAllRoutines()`, `getAllTargets()`, `getAllMuscleGroups()`, `getCustomExercises()`, `getAllTrainingPrograms()`, `getAllPersonalRecords()`, `getAllConversations()`, plus raw settings keys) and write each into `SqliteStorageService` through its normal write methods. This trusts only the new write path — reads reuse logic that already works.
3. Only if every entity type migrates without throwing: write `storage_migrated_v1 = true` into the Hive settings box.
4. From that point on (this launch and all future launches), `AppInitializer` hands `WorkoutProvider` a `SqliteStorageService` instead of `StorageService`.
5. If migration throws partway through anything, the flag is never set. The app falls back to `StorageService` (Hive) for that launch, and retries the full migration on the next app start. There is no partial-migration state a user can get stuck in.
6. **Hive boxes are never deleted.** They remain on disk indefinitely as a passive backup — the data volume for a personal fitness log is small, so the disk cost is negligible next to the safety value.

The migration writes entities sequentially and sets storage_migrated_v1 only after all writes succeed. If a later entity fails, SQLite retains earlier writes. The next launch then retries against a partially populated database, which can cause primary-key conflicts or duplicate child data.

Run the complete migration in one transaction or delete and recreate the SQLite database before retrying. Add failure tests after each entity type.

around lines 188 - 193, Update the migration flow in AppInitializer so a failed
migration cannot leave partial SQLite data: execute all entity writes in one
transaction, or delete and recreate the SQLite database before the next retry.
Preserve setting storage_migrated_v1 only after complete success and Hive
fallback on failure, and add failure tests after each migrated entity type to
verify retry safety.


This keeps the app in exactly one of two well-defined states at all times: fully on Hive, or fully on SQLite.

## 7. Coach SQL Tool: `run_sql_query`

Added to `CoachToolService.buildTools()` / `handleCall()`, alongside (not replacing) the existing curated tools.

- **Connection:** a dedicated **read-only** `sqflite` connection (`openReadOnlyDatabase`) to the same database file used by `SqliteStorageService`. This is the real safety boundary — the OS/SQLite layer itself refuses writes on this connection, regardless of what SQL text is submitted.
- **Text validation (defense-in-depth, not the primary guard):** trim the query, strip a single trailing `;`, reject if a second `;` remains (multi-statement), reject case-insensitively if it doesn't start with `SELECT` or `WITH`, reject if it contains `insert|update|delete|drop|alter|create|attach|detach|pragma|vacuum|replace|trigger` as a keyword.
- **Row cap:** wrap the model's query as `SELECT * FROM (<query>) LIMIT ?` with a default of 200, model-adjustable up to 500 — never trusts a `LIMIT` the model wrote itself.

sqflite openReadOnlyDatabase singleInstance default same path existing database official API documentation

💡 Result:

In the sqflite library, the openReadOnlyDatabase function is a convenience method that calls openDatabase with the readOnly parameter set to true [1][2]. Regarding the behavior of singleInstance: 1. Default Behavior: By default, singleInstance is true [1][3][4]. When true, sqflite returns a single database instance for a given path [3][4]. 2. Subsequent Calls: If you call openDatabase or openReadOnlyDatabase with the same path while singleInstance is set to true, the library will return the existing database instance rather than opening a new one [3][4]. 3. Parameter Handling: When singleInstance is true and you re-open an existing database, the library discards all other parameters (such as callbacks) provided in that subsequent call [3][4]. 4. Best Practice: It is strongly recommended to open a database only once [5]. Because openDatabase is asynchronous, you should manage your database instance carefully to avoid race conditions, typically by using a helper pattern to ensure it is initialized only once [5]. If you set singleInstance to false, each call will attempt to open a new connection to the database, which can lead to errors such as "database is locked" (SQLiteDatabaseLockedException), particularly on platforms like Android [5].

🌐 Web query:

site:pub.dev/documentation/sqflite/latest/sqflite/openReadOnlyDatabase.html openReadOnlyDatabase singleInstance

💡 Result:

The openReadOnlyDatabase function is part of the sqflite library for Dart and Flutter [1]. The singleInstance parameter is a boolean that defaults to true [1]. When set to true, the library returns the existing database instance if one has already been opened for the specified path, rather than creating a new connection [1]. In the context of openReadOnlyDatabase, the function is implemented as follows [1]: Future openReadOnlyDatabase( String path, { bool? singleInstance = true, }) => openDatabase(path, readOnly: true, singleInstance: singleInstance);

Citations:


Use an isolated read-only sqflite connection.

openReadOnlyDatabase defaults singleInstance to true. If the same path already has a writable instance, sqflite can return it and ignore the new readOnly option. Set singleInstance: false and test that writes fail on every supported platform.

- **Error handling:** any exception (syntax error, cap violation, etc.) returns `{'error': message}`, matching every other tool's contract — a bad query is a recoverable turn, not a crash.
- **Function description** embeds the full schema (table + column names, one line each) so the model always has it in context without a separate schema-discovery round trip.

---

## 8. Testing

- **`SqliteStorageService`**: new test file, run against an in-memory database via `sqflite_common_ffi` (`databaseFactory = databaseFactoryFfi`, `inMemoryDatabasePath`). Covers every `IStorageService` method, mirroring the existing `MockStorageService`-based test patterns for shape.
- **Migration**: seed a `StorageService` (Hive, using the existing test Hive setup) with representative data across every entity type, run the migration routine against a fresh in-memory `SqliteStorageService`, assert the data matches, assert the flag is set, assert re-running the migration is a no-op (skips already-migrated).
- **Existing test suite** (managers, `WorkoutProvider`, screens): unaffected — all depend on `IStorageService`/`MockStorageService`, never the concrete backend.
- **`run_sql_query`**: valid `SELECT` → correct JSON rows; non-`SELECT` → rejected with error; multi-statement → rejected; row cap enforced; schema-referencing query (e.g. a join across `sessions`/`exercise_logs`/`sets`) returns expected shape.

---

## 9. Rollout Notes

- `pubspec.yaml` additions: `sqflite` (runtime), `sqflite_common_ffi` (dev, for tests).
- `hive`/`hive_flutter` dependencies and `StorageService` (Hive) are **kept**, not removed — they remain the migration source and the pre-migration fallback path indefinitely (or until a future spec decides it's safe to drop them, informed by real-world migration success rates).
- No changes to `CLAUDE.md`'s documented Hive box list are needed for this spec beyond noting the SQLite migration exists; a follow-up doc update once this ships is reasonable but out of scope here.
