feat: Add --base-href support to flutter run for web by Mastersam07 · Pull Request #182709 · flutter/flutter

Mastersam07 · 2026-02-21T13:51:52Z

Description

Adds --base-href support to the flutter run command for web targets.

Previously, --base-href was only available on flutter build web, which meant developers testing web apps hosted in subfolders had to manually edit web/index.html during development and undo the change before committing. This PR brings the same flag to flutter run, so the dev server correctly serves the app with a custom base path.

Usage

flutter run -d chrome --base-href=/preview/

The value must start and end with /, matching the same validation as flutter build web --base-href.

Fixes#163141

Code Review

This pull request adds support for the --base-href flag to the flutter run command for web targets, which is a valuable addition for developers testing applications in subfolders. The implementation correctly handles template substitution and server routing. I've noted a few improvements: ensuring the value is also read from the configuration file, adding the missing parsing logic in WebDevServerConfig.fromYaml, and using existing utility functions for cleaner string manipulation.

Thanks for adding this!

LGTM with a suggestion to deduplicate the flag between run and build.

This needs its own usesWebBaseHrefFlag() that is shared between run and build.

True, since --base-href flag is duplicated; defined separately across both

As reported in this failure, some files need to be dart-formatted:
