API

System brightness

Future<double> get systemBrightness async {

  } catch (e) {
    print(e);
    throw 'Failed to get system brightness';
  }
}

Current brightness

Future<double> get currentBrightness async {
  try {
    return await ScreenBrightness().current;
  } catch (e) {
    print(e);
    throw 'Failed to get current brightness';
  }
}

Set brightness

Future<void> setBrightness(double brightness) async {
  try {
    await ScreenBrightness().setScreenBrightness(brightness);
  } catch (e) {
    print(e);
    throw 'Failed to set brightness';
  }
}

reset brightness

Future<void> resetBrightness() async {
  try {
    await ScreenBrightness().resetScreenBrightness();
  } catch (e) {
    print(e);
    throw 'Failed to reset brightness';
  }
}

current brightness changed stream

@override
Widget build(BuildContext context) {
  return StreamBuilder<double>(
    stream: ScreenBrightness().onCurrentBrightnessChanged,
    builder: (context, snapshot) {
      double changedBrightness = currentBrightness;
      if (snapshot.hasData) {
        changedBrightness = snapshot.data!;
      }
        
      return Text('current brightness $changedBrightness');
    },
  );
}

Usage

• DON'T use didChangeAppLifecycleState to set or reset brightness because this plugin already implemented this function.
• You may also use this plugin with wakelock to prevent screen sleep
