• Device dataset Updated

0.0.1

• Initial release.

Highlights

• Public API: CornerRadiusPlugin.init(), CornerRadiusPlugin.screenRadius, and CornerRadiusPlugin.setDefaultRadius(double) to initialize, read and configure a fallback radius.
• Data model: CornerRadius value object with per-corner radii (topLeft, topRight, bottomLeft, bottomRight).
• Android support: Uses Android 12+ RoundedCorner APIs (via WindowInsets) to return per-corner radii. On older Android versions falls back to the rounded_corner_radius system dimension when available; otherwise returns zeros (or the configured default radius).
• iOS support: Bundles assets/bezel.min.json (BezelKit dataset) and looks up device-specific bezel/corner radius by model identifier (e.g. iPhone14,2). The JSON lookup runs on a background isolate to avoid blocking the UI.
• Method channel platform interface: getScreenRadius() and getDeviceInfo() are implemented via method channels so platform implementations can be overridden in tests or by federated plugins.

Behavior and usage notes

• Call await CornerRadiusPlugin.init() early in app startup (for example in main() or initState) to populate CornerRadiusPlugin.screenRadius.
• On iOS the plugin queries the native platform for the device model and device type then performs a JSON lookup in bezel.min.json. If the lookup fails or returns zero, the configured default radius will be used.
• Use CornerRadiusPlugin.setDefaultRadius(5.0) to set a non-zero fallback radius for devices where native APIs or dataset entries are unavailable.

Assets and maintenance

• assets/bezel.min.json is included in the package and is intended to be periodically updated (the project contains an auto-update workflow in the example README). The plugin reads the JSON from package assets at runtime.

Developer notes (internal)

• The Dart implementation exposes a platform interface in lib/src/corner_radius_plugin_platform_interface.dart and a method channel implementation in lib/src/corner_radius_plugin_method_channel.dart.
• The lookup helper _lookupBezelForModel is run on a background isolate via compute() and loads the JSON from packages/corner_radius_plugin/assets/bezel.min.json.
