      controller1.repeat(
          min: 0, max: 53, period: const Duration(milliseconds: 200));
    });
    WidgetsBinding.instance.addPostFrameCallback((_) {
      controller2.repeat(
          min: 0, max: 13, period: const Duration(milliseconds: 200));
      controller4.repeat(
          min: 0, max: 13, period: const Duration(milliseconds: 200));
    });
    controller3 = GifController(
        vsync: this,
        duration: const Duration(milliseconds: 200),
        reverseDuration: const Duration(milliseconds: 200));
