| |
| // This program generates getMaterialTranslation(), getCupertinoTranslation(), |
| // and getWidgetsTranslation() functions that look up the translations provided by |
| // the arb files. The returned value is a generated instance of a |
| // GlobalMaterialLocalizations, GlobalCupertinoLocalizations, or |
| // GlobalWidgetsLocalizations object that corresponds to a single locale. |
| // |
| // The *.arb files are in packages/flutter_localizations/lib/src/l10n. |
| // |
| // The arb (JSON) format files must contain a single map indexed by locale. |
| // Each map value is itself a map with resource identifier keys and localized |
| // resource string values. |
| // |
| // The arb filenames are expected to have the form "material_(\w+)\.arb" or |
| // "cupertino_(\w+)\.arb" where the group following "_" identifies the language |
| // code and the country code, e.g. "material_en.arb" or "material_en_GB.arb". |
| // In most cases both codes are just two characters. |
| // |
| // This app is typically run by hand when a module's .arb files have been |
| // updated. |
| // |
| // ## Usage |
| // |
| // Run this program from the root of the git repository. |
| // |
| // The following outputs the generated Dart code to the console as a dry run: |
| // |
| // ``` |
| // dart dev/tools/localization/bin/gen_localizations.dart |
| // ``` |
| // |
| // If you have removed localizations from the canonical localizations, then |
| // add the '--remove-undefined' flag to also remove them from the other files. |
| // |
| // ``` |
| // dart dev/tools/localization/bin/gen_localizations.dart --remove-undefined |
| // ``` |
| // |
| // If the data looks good, use the `-w` or `--overwrite` option to overwrite the |
| // generated_material_localizations.dart, generated_cupertino_localizations.dart, |
| // and generated_widgets_localizations.dart files in packages/flutter_localizations/lib/src/l10n/: |
| // |
| // ``` |
| // dart dev/tools/localization/bin/gen_localizations.dart --overwrite |
