Describe the bug
连续show有mask的loading，会看到mask背景闪烁（mask没有过渡效果）
实际场景为：
登录的时候需要连续request多个api，每次request都会show和dismiss loading

Code

void configLoading() {
  EasyLoading.instance
    ..displayDuration = 60.seconds
    ..indicatorType = EasyLoadingIndicatorType.ring
    ..loadingStyle = EasyLoadingStyle.custom
    ..maskType = EasyLoadingMaskType.custom
    // ..animationStyle = EasyLoadingAnimationStyle.scale
    ..maskColor = Colors.blue.withOpacity(0.5)
    ..contentPadding = const EdgeInsets.all(20)
    // ..indicatorWidget = LoadingWidget()
    // ..indicatorSize = 45
    ..radius = 10.0
    // ..progressColor = Colors.yellow
    ..backgroundColor = Color(0xFFD5D66A).withOpacity(0.8)
    ..indicatorColor = Color(0xFFD5D66A)
    ..textColor = Colors.white
    ..textStyle = const TextStyle(
      color: Colors.white,
      fontSize: 15,
      fontWeight: FontWeight.w500,
    )
    // ..maskColor = Colors.blue.withOpacity(0.5)
    ..userInteractions = false
    ..dismissOnTap = false;
  // ..customAnimation = CustomAnimation();
}

Future<void> showLoading() async {
    EasyLoading.show(status: 'Loading...');
    await Future.delayed(Duration(seconds: 1));
    EasyLoading.dismiss();
  }

await showLoading();
    await showLoading();
    await showLoading();

Start with the configLoading and showLoading example, then reproduce the repeated EasyLoading.show and EasyLoading.dismiss sequence. Trace the mask presentation and dismissal path in the repository and check how its animation is configured. Done means consecutive masked loading calls no longer visibly flash the mask background.
