Have you had experience developing or interacting with native code in Flutter projects?

Yes, in Flutter, you can interact with native code through platform channels. This allows calling Java/Kotlin code for Android and Objective-C/Swift for iOS from Flutter when access to platform-specific features is needed.

Example: if you need to get device battery data that is not available in standard Flutter plugins, you can write native code and call it from Flutter via MethodChannel.

// Flutter side
static const platform = MethodChannel('samples.flutter.dev/battery');

Future<int> getBatteryLevel() async {
  final int batteryLevel = await platform.invokeMethod('getBatteryLevel');
  return batteryLevel;
}

On the Android side, a corresponding method is written to handle the call and return data.
