getDefinition method

  1. @override
Map<String, TweenList> getDefinition({
  1. Size? screenSize,
  2. Size? widgetSize,
})
override

AnimatorWidget calls getDefinition to gather the animation. Animations are defined using named TweenLists using a Map<String, TweenList>. Example: @override Map<String, TweenList> getDefinition({Size screenSize, Size widgetSize}) { return { "opacity": TweenList

Implementation

@override
Map<String, TweenList> getDefinition({Size? screenSize, Size? widgetSize}) {
  final curve = Cubic(0.215, 0.61, 0.355, 1);
  return {
    "opacity": TweenList<double>(
      [
        TweenPercentage(percent: 0, value: 0.0, curve: curve),
        TweenPercentage(percent: 60, value: 1.0, curve: curve),
      ],
    ),
    "translateY": TweenList<double>(
      [
        TweenPercentage(percent: 0, value: screenSize!.height, curve: curve),
        TweenPercentage(
            percent: 60, value: -25.0 * preferences.magnitude, curve: curve),
        TweenPercentage(
            percent: 75, value: 10.0 * preferences.magnitude, curve: curve),
        TweenPercentage(
            percent: 90, value: -5.0 * preferences.magnitude, curve: curve),
        TweenPercentage(percent: 100, value: 0.0, curve: curve),
      ],
    ),
  };
