Tapping animation can be inconsistent

[mintcollege]

I noticed that sometimes the animation won't scale to the value of end after multiple taps. Is there perhaps a trigger which is still running which prevents the overlapping of tap animations?

I tried this with successive fast taps (500ms gap) and slow taps (1-2 sec gap). If I could guess I'd say out of 10 taps the animation would trigger about 7 times.

These are my settings:

ZoomTapAnimation(
      onTap: () => print('tap'),
      begin: 1.0,
      end: 0.9,
      beginCurve: Curves.decelerate,
      endCurve: Curves.fastOutSlowIn,
      child: child
    );

I thought perhaps the curves were causing this but apparently that's not the case. Btw, the onTap callback works fine it's just the animation that's not consistent. Any possible fixes for this?
