Animated Resize on ShadResizableController

[arthurbcd]

I made my own solution to animate ShadResizableController.resize, it's actually performant.

I'm not sure if you are interested in adding it to your ShadResizableController , but for those interested, here is my implementation:

extension ShadResizableControllerAnimatedExtension on ShadResizableController {
  void resizeAnimated({
    required int index,
    required double size,
    Duration duration = const Duration(milliseconds: 3000),
    Curve curve = Curves.fastOutSlowIn,
  }) {
    final info = getPanelInfo(index);
    if (info.size == size) return;

    final tween = Tween(begin: info.size, end: size);
    final tweenCurved = CurveTween(curve: curve);

    Duration? totalTime;
    Duration durationLeft = duration;

    void tick() {
      final t = 1 - (durationLeft.inMilliseconds / duration.inMilliseconds);
      final tCurved = tweenCurved.transform(t);
      final currentSize = tween.transform(tCurved);

      resetDefaultSizes(index, index + 1);
      resize(index: index, size: currentSize);

      WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
        final elapsed = timeStamp - (totalTime ??= timeStamp);
        durationLeft -= elapsed;

        if (durationLeft <= Duration.zero) {
          resetDefaultSizes(index, index + 1); // <- idk if it's a package bug, but I must call it before, or it throws.
          resize(index: index, size: size);
          return;
        }

        tick();
      });
    }

    tick();
  }
}
