corner_radius_plugin

Flutter plugin to get the current device screen corner radius on Android and iOS.

• Android: uses Android 12+ RoundedCorner via WindowInsets, with fallback to the system dimen rounded_corner_radius when available.
• iOS: integrates a BezelKit hook for accurate device bezels

Inspired by and Android logic adapted from screen_corner_radius GitHub repo. For iOS bezel data, see BezelKit GitHub repo and documentation at swiftpackageindex.com/markbattistella/BezelKit/documentation.

Install

Add to your pubspec.yaml:

dependencies:
  corner_radius_plugin: any

Usage

Initialize during app startup, e.g. in main() or initState().

import 'package:corner_radius_plugin/corner_radius_plugin.dart';

final screenRadius = await CornerRadiusPlugin.init();
if (screenRadius != null) {
  print('TL: ${screenRadius.topLeft}');
}

Get radius

final screenRadius =  CornerRadiusPlugin.screenRadius;

Setting default value

CornerRadiusPlugin.setDefaultRadius(5.0);

iOS: Bezel data via BezelKit JSON

The plugin bundles bezel.min.json from BezelKit and looks up the radius by device model identifier (e.g. iPhone14,2). The JSON is auto-updated weekly via GitHub Actions.

• Source JSON: bezel.min.json
• Auto updater workflow: .github/workflows/update_bezel_json.yml

At runtime the plugin:

• Reads assets/bezel.min.json (auto-refreshed weekly)
• Gets the current model with getModelIdentifier platform method on iOS
• Returns the device bezel value using "bezel" (or legacy "bazel") key; Android uses native API, iOS uses JSON lookup

Android Notes

On Android 12 (API 31)+ the radii are per-corner. On lower APIs, a single value from rounded_corner_radius is used when available; otherwise zeros are returned.
