AnimationController.animateWith() called after AnimationController.dispose()

[Martin Rupert Bulquerin]

I got this error after I dismiss the dialog with BallPulseIndicator then navigate to another page.

I've got a similar exception using BallPulseIndicator in StreamBuilder during the waiting state:

AnimationController.stop() called after AnimationController.dispose() AnimationController methods should not be used after calling dispose.

And I've found that removing async and await keywords in startAnims method, just like the one in ball_beat_indicator.dart, seems to fix the issue. I don't know why, but please check this out. Thanks in advance.

Confirming the same issue in version 1.0.2

You can fix it by adding if (context.mounted)

@OverRide
void startAnim(AnimationController controller) {
if (context.mounted) {
controller.repeat(reverse: true);
}
}

[Mohamed Abadllah]

in
@override startAnims(List<AnimationController> controllers)
you can simply replace
controllers[i].repeat(reverse: true);
with
if (context.mounted) controllers[i].repeat(reverse: true);
I made hot fix with pull request #15

Hi!
Same for me, but Mohamed, I will try your fix, hopefully will work. Thank you.
Did you only try to merge this fix, but still no response from the author?
By the way, I did not want to fork this repository, but its clear now that I have to do it. I fork too many repos now, because of similar bugfixes...
