Flutter build Ios failed using internationalization (intl)

[printpagestopdf]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

My flutter Project is using intl following this https://docs.flutter.dev/ui/accessibility-and-internationalization/internationalization walkthrough. Especially this part:
I have a file called l10n.yaml in projects root with this content:
arb-dir: lib/l10n
template-arb-file: app_en.arb
output-localization-file: app_localizations.dart

In dart code importing:
import 'package:flutter_gen/gen_l10n/app_localizations.dart';

The ios build process complains that it cannot find package flutter_gen:
Error (Xcode): Error: Couldn't resolve the package 'flutter_gen' in 'package:flutter_gen/gen_l10n/app_localizations.dart'.

My assumption is, that intl package is defining a synthetic package (by l10n.yaml) and the build process cannot resolve it. But I habe no idea how to solve it.

Expected results

Build process should not fail because of not finding lutter_gen

Actual results

The ios build process complains that it cannot find package flutter_gen:
Error (Xcode): Error: Couldn't resolve the package 'flutter_gen' in 'package:flutter_gen/gen_l10n/app_localizations.dart'.

Hello @printpagestopdf , can you please check out this comment. It does sound like a known issue being tracked here, you can follow up on it for further updates

Sorry for my late reply but I was suffering from an infection. The comment you mentioned seemed to be the reason. I used the workaround mentioned there (moving synthetic package to real package). Not an elegant solution, but its working now.
Many thanks
