AppLocalizations class from flutter_gen does not show in completion/have import fix #3948
Description
Describe the bug
When using flutter_localizations, the extension doesn't lint/track AppLocalizations nor its import 'package:flutter_gen/gen_l10n/app_localizations.dart' automatically.
To Reproduce
Steps to reproduce the behavior:
- Install and setup
flutter_localizations - Go in any dart file and try to type
AppLocalizations: no Quick Fix available, and we have to import the package manually.
Expected behavior
It should suggest import 'package:flutter_gen/gen_l10n/app_localizations.dart' in the Quick Fixes dropdown list.
Screenshots
Please complete the following information:
- Operating System and version: Windows 10.0.19044.1645
- VS Code version: 1.66.2
- Dart extension version: 3.40.0
- Dart/Flutter SDK version: Channel stable, 2.10.4

@bwilkerson it seems the reason for this is that the
flutter_genpackage is not explicitly listed inpubspec.yaml, so the server doesn't suggest it for any import fixes (or its paths when typing animport 'package:import).The
flutter_genpackage is injected only into.dart_tool/package_config.jsonduringflutter pub get, but it is intended to be referenced directly by user code (see here).If I manually add
flutter_gento my pubspec (after letting Flutter create it and add it to.dart_tool/package_config.json) then the quick-fix shows up (although, I still don't get completion for paths on theimport):I'm not sure what a good fix for this is. Flutter injecting
flutter_geninto.dart_tool/package_config.jsonwithout it being inpubspechas always seemed slightly odd and a change to the Linter'sdepend_on_referenced_packageslint was described as "a hack" in dart-lang/sdk#58690, so I don't know if fixing it as-is in the server would just be adding more debt?axiftaj commentedon Jun 14, 2023
I can confirm this error still exists. I have to manually import import 'package:flutter_gen/gen_l10n/app_localizations.dart' to access AppLocalizations in the app.
Also it's very strange it's been one year and this didn't get fixed.

This issue is blocked on flutter/flutter#102983. The way Flutter currently generates this package means it's not listed in
pubspec.yamland the analysis server will only suggest things that are direct dependencies.intl docs: Remove instruction to import bindings file

Still facing this issue.

There's an upcoming change to Flutter so that localized messages live inside the application source (and not a synthetic package), see:
package:flutter_genflutter/flutter#102983--explicit-package-dependenciesby default. flutter/flutter#160289This resolves this problem because they won't be in a package that's injected only into
package_config.json, but instead will live inside your project like any other code.sallytimmer commentedon May 11, 2025
The solution is to set this command in the project root terminal:
flutter config --no-explicit-package-dependencies
That will undo this settings:
flutter config --explicit-package-dependencies
