AnimatedWidgets library calling using AnimationController methods after dispose

[parthraghav]

I'm using CustomAnimatedWidget. However, sometimes a frame-drop occurs and the app throws an exception saying that the AnimationController methods should not be used after calling dispose. The error originates in the library. Hoping to see a fix soon!

Code:

CustomAnimatedWidget(
      enabled: _isVisible,
      duration: Duration(milliseconds: 300),
      curve: Curves.easeOut,
      builder: (context, percent) {
        final double animatedScale = 1 * percent;
        final double animatedOpacity = 1 * percent;
        final double animatedClipHeightFactor = 0.7 + 0.3 * percent;

        return Transform.scale(
          scale: animatedScale,
          alignment: Alignment.center,
          child: ...
        );
      },
      animationFinished: (bool smthn) {
        Debugging.log("animation finished");
      },
    );

Error trace:
