如何高度自定义SmartDialog动画？

[ddxl123]

SmartAnimationType 只有四种选择。

• 这个功能完成了, 请升级下版本

dependencies:
  flutter_smart_dialog: ^4.5.5+2

• 简易用法
  • 必须使用提供的AnimationController
  • 请注意：该用法适用于只使用一个AnimationController的场景

SmartDialog.show(
  animationTime: const Duration(milliseconds: 3000),
  animationBuilder: (
    AnimationController controller,
    Widget child,
    AnimationParam animationParam,
  ) {
    return RotationTransition(
      turns: CurvedAnimation(parent: controller, curve: Curves.elasticIn),
      child: child,
    );
  },
  builder: (_) {
    return Container(
      color: Colors.white,
      padding: const EdgeInsets.all(30),
      child: const Text('custom animation dialog'),
    );
  },
);

• 进阶用法
  • 如果你不想使用回传的AnimationController或者你的动画需要使用多个AnimationController，可以使用进阶用法
  • onForward和onDismiss闭包参数必须要赋值，因为需要在内部把控开始动画和结束动画的时机（动画reverse结束后，才会移除当前的dialog）
  • 如果还想定制遮罩的动画，可以将mask设置为透明色，自己去自定义遮罩层，对其设置想要的动画

SmartDialog.show(
  animationTime: const Duration(milliseconds: 3000),
  animationBuilder: (
    AnimationController controller,
    Widget child,
    AnimationParam animationParam,
  ) {
    return CustomAnimation(child: child, animationParam: animationParam);
  },
  builder: (_) {
    return Container(
      color: Colors.white,
      padding: const EdgeInsets.all(30),
      child: const Text('custom animation dialog'),
    );
  },
);

class CustomAnimation extends StatefulWidget {
  const CustomAnimation({
    Key? key,
    required this.child,
    required this.animationParam,
  }) : super(key: key);

  final Widget child;

  final AnimationParam animationParam;

  @override
  State<CustomAnimation> createState() => _CustomAnimationState();
}

class _CustomAnimationState extends State<CustomAnimation>
    with TickerProviderStateMixin {
  late AnimationController _controller;

  @override
  void initState() {
    _controller = AnimationController(
      vsync: this,
      duration: widget.animationParam.animationTime,
    );
    widget.animationParam.onForward = () {
      _controller.value = 0;
      _controller.forward();
    };
    widget.animationParam.onDismiss = () {
      _controller.reverse();
    };

    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return RotationTransition(
      turns: CurvedAnimation(parent: _controller, curve: Curves.elasticIn),
      child: widget.child,
    );
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
}
