What is a .arb file?

An ARB file (.arb, Application Resource Bundle) is a JSON-based localization format used by Flutter and Google tools. Alongside each key's translated string it stores metadata in a matching @key object — a description and typed placeholders — and uses ICU message syntax with {name} placeholders and plural/select rules.

How to use this file

Use an example .arb file to test Flutter's gen-l10n pipeline, ARB editors and converters, and ICU message-syntax parsers, or to exercise placeholder and plural handling.
