getDefinition method

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

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}) {
  return {
    "opacity": TweenList<double>(
      [
        TweenPercentage(percent: 30, value: 1.0),
        TweenPercentage(percent: 100, value: 0.0),
      ],
    ),
    "rotateY": TweenList<double>(
      [
        TweenPercentage(percent: 0, value: 0.0),
        TweenPercentage(percent: 30, value: -20.0 * toRad),
        TweenPercentage(percent: 100, value: 90.0 * toRad),
      ],
    ),
  };
}
