Avoid static methods so we can mock it

Hi. I was wondering if you could make it to use class methods instead of static ones, so we could mock it on Unit tests (perhaps using Singleton pattern would help?). Thanks.

You can mock

You could do this

class VibrationController {
  static Future<bool?> Function() hasCustomVibrationsSupport = Vibration.hasCustomVibrationsSupport;
  static Future<void> Function({int duration}) vibrate = Vibration.vibrate;


  Future<void> call(int duration) async {
      await VibrationService.vibrate(duration: duration);
  }
}

So in the test

  test('Test Vibration', () {
    var called = 0;

    VibrationController .vibrate = ({int duration = 500}) async {
      called++;
    };
    VibrationController .hasCustomVibrationsSupport = () async {
      return true;
    };
    sut.call(
      parameters: {
        'duration': 200,
      },
    );
      expect(called, 1);
      expect(durationCount, 200);
  });
