AnimationParam class

advanced usage:

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();
  }
}

Constructors

AnimationParam({required Alignment alignment, required Duration animationTime, VoidCallback? onForward, VoidCallback? onDismiss})

Properties

alignment ↔ Alignment

showXxx#alignment

getter/setter pair

animationTime ↔ Duration

showXxx#animationTime

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

onDismiss ↔ VoidCallback?

The animation end callback, indicates that the dialog is about to close, if you use custom or multiple AnimationController, you should use reverse() in this callback to reverse the animation

getter/setter pair

onForward ↔ VoidCallback?

The animation starts callback, indicating that the dialog is about to open; if you use custom or multiple AnimationControllers, the animation should be run using forward() in this callback

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
