I found a way how to bypass it just wanted to run the project, I changed imports in I10n.dart
import 'generated/app_localizations.dart';
import 'package:flutter/widgets.dart';
export 'generated/app_localizations.dart';
extension AppLocalizationsX on BuildContext {
AppLocalizations get l10n => AppLocalizations.of(this);

output-localization-file: app_localizations.dart
nullable-getter: false
synthetic-package: false
output-dir: lib/l10n/generated
