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 a = 0.0;
  final b = -10.0 * preferences.magnitude;
  final c = 10.0 * preferences.magnitude;
  return {
    "translateX": TweenList<double>(
      [
        TweenPercentage(percent: 0, value: a),
        TweenPercentage(percent: 10, value: b),
        TweenPercentage(percent: 20, value: c),
        TweenPercentage(percent: 30, value: b),
        TweenPercentage(percent: 40, value: c),
        TweenPercentage(percent: 50, value: b),
        TweenPercentage(percent: 60, value: c),
        TweenPercentage(percent: 70, value: b),
        TweenPercentage(percent: 80, value: c),
        TweenPercentage(percent: 90, value: b),
        TweenPercentage(percent: 100, value: a),
      ],
    ),
  };
}
