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 floorCurve = Cubic(0.215, 0.61, 0.355, 1);
  final ceilCurve = Cubic(0.755, 0.05, 0.855, 0.06);
  return {
    "translateY": TweenList<double>(
      [
        TweenPercentage(percent: 0, value: 0.0, curve: floorCurve),
        TweenPercentage(percent: 20, value: 0.0, curve: floorCurve),
        TweenPercentage(
            percent: 40,
            value: -30.0 * preferences.magnitude,
            curve: ceilCurve),
        TweenPercentage(
            percent: 43,
            value: -30.0 * preferences.magnitude,
            curve: ceilCurve),
        TweenPercentage(percent: 53, value: 0.0, curve: floorCurve),
        TweenPercentage(
            percent: 70,
            value: -15.0 * preferences.magnitude,
            curve: ceilCurve),
        TweenPercentage(percent: 80, value: 0.0, curve: floorCurve),
        TweenPercentage(percent: 90, value: -4.0 * preferences.magnitude),
        TweenPercentage(percent: 100, value: 0.0, curve: floorCurve),
      ],
    ),
  };
