  1. @override
void createTweens()

Build the animations driven by controller. Called from initState after controller has been created.

Implementation

@override
void createTweens() {
  final CurvedAnimation curved =
      CurvedAnimation(parent: controller, curve: widget.curve);

  _scaleX = TweenSequence<double>(<TweenSequenceItem<double>>[
    TweenSequenceItem(tween: Tween(begin: 1.0, end: 1.25), weight: 30),
    TweenSequenceItem(tween: Tween(begin: 1.25, end: 0.75), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 0.75, end: 1.15), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 1.15, end: 0.95), weight: 15),
    TweenSequenceItem(tween: Tween(begin: 0.95, end: 1.05), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 1.05, end: 1.0), weight: 25),
  ]).animate(curved);

  _scaleY = TweenSequence<double>(<TweenSequenceItem<double>>[
    TweenSequenceItem(tween: Tween(begin: 1.0, end: 0.75), weight: 30),
    TweenSequenceItem(tween: Tween(begin: 0.75, end: 1.25), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 1.25, end: 0.85), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 0.85, end: 1.05), weight: 15),
    TweenSequenceItem(tween: Tween(begin: 1.05, end: 0.95), weight: 10),
    TweenSequenceItem(tween: Tween(begin: 0.95, end: 1.0), weight: 25),
