Flutter Slang I18n

Workflow

1. Check project state before edits.
   • Run git status --short and follow the repository's change-safety policy before modifying files.
   • Find the Flutter package root containing pubspec.yaml.
   • If .fvm/fvm_config.json exists, run Flutter and Dart commands through fvm.
   • Inspect existing localization (slang.yaml, build.yaml, lib/i18n, intl, ARB, easy_localization) before adding another system. If replacing an existing i18n stack, call out migration risk first.
