slang 3.2.0

Localization / Internationalization (i18n) solution. Use JSON, YAML or CSV files to create typesafe translations via source generation.

3.2.0

• feat: add command flutter pub run slang:apply to add translations from the slang:analyze result
• fix: handle isFlatMap parameter when overriding translations correctly
• fix: update arb migration tool to respect new modifier syntax

3.1.0

• feat: add command flutter pub run slang:analyze to report missing translations

3.0.0

Translation Overrides and Enhanced Modifiers

• feat: it is now possible to override translations via LocaleSettings.overrideTranslations (checkout updated README)
• feat: there is a new modifier syntax which allows for multiple modifiers e.g. myKey(plural, rich)
• feat: improve file scan (now only checks top-level directory for any config files)
• Breaking: default plural parameter is now n; you can revert this by setting pluralization/default_parameter: count
• Breaking: custom plural/context parameter must follow syntax apples(param=appleCount)

All breaking changes will result in a compile-time error, so don't worry for "hidden" bugs :)
