v4.0.0

DateFormat, NumberFormat, and Lazy loading

Format translations with DateFormat and NumberFormat:

Hello {name}, today is {today: yMd}. You have {money: currency(symbol: '€')}.

On web, Deferred loading is used to reduce initial load time.

• feat: add DateFormat and NumberFormat support (#112)
• feat: add lazy: true config which is enabled by default (#135)
• fix: slang analyze should not treat translations as unused if they are used in linked translations (#231)
• fix: slang analyze should detect missing enums (#234)
• fix: trim enum keys in compressed format while parsing (e.g. "male, female": "..." to "male,female": "...") (#247)
• fix: compilation error on web when using large interfaces (#251)
• fix: correctly transform keys with modifiers when key_case is set (#253)
• Breaking: Require Dart 3.3 and Flutter 3.19
• Breaking: setLocale, setLocaleRaw, and useDeviceLocale returns a Future, use -Sync suffix for synchronous calls
• Breaking: output_format removed, always generates multiple files now
• Breaking: deprecated functions in LocaleSettings (supportedLocales, supportedLocalesRaw) removed
• Breaking: defining contexts (enums) is no longer allowed in build.yaml or slang.yaml (deprecated in v3.19.0)
• Breaking: enums specified in context are no longer transformed into pascal case keeping the original case
