JsonAssetLoader class

The JSON Asset Loader.

Loads translation files from assets/lang/{locale}.json.

Setup

  1. Create translation files in assets/lang/:

    • assets/lang/en.json
    • assets/lang/tr.json

  2. Register in pubspec.yaml:

    flutter:
  assets:
    - assets/lang/

JSON Format

Supports nested keys that will be flattened:

{
  "welcome": "Welcome, :name!",
  "auth": {
    "failed": "Login failed.",
    "throttle": "Too many attempts."
  }
}

Becomes: auth.failed, auth.throttle
