Confetti package animation not displaying correctly upon scroll

[Aristidios]

I'm using Package Confetti 0.6.0 ConfettiWidget() within Card()s generated in a GridView.builder

Upon scroll the animation stops working properly & even vanishes if I scroll too much.

I thought the issue had to do with lazy loading, so I tried two other particle animation widgets:

1. Particles 0.1.4 and
2. Animated Background 2.0.0

Both of which worked fine, displaying correct animation - even through scrolling.

-> It could be just an issue with Package Confetti 0.6.0, but I think the problem might come from the way I'm initializing the ConfettiController and calling .play() method & disposing of it.

Here is my complete simplified code:

class HomePage extends StatefulWidget {
  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  late ConfettiController _controllerCenter;

  @override
  void initState() {
    super.initState();
    _controllerCenter =
        ConfettiController(duration: const Duration(seconds: 1000));
    _controllerCenter.play();
  }

  @override
  void dispose() {
    _controllerCenter.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      body: SafeArea(
        child: new GridView.builder(
          itemCount: 30,
          itemBuilder: (BuildContext context, int index) {
            return Card(
              child: Center(
// 
                child: ConfettiWidget(
                  confettiController: _controllerCenter,
                  shouldLoop: true,
                ),
//
              ),
            );
          },
          gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
            crossAxisCount: 2,
          ),
        ),
      ),
    );
  }
}

-> I'd like to keep the animation running despite scrolling through the GridView.

I need to use a GridView.builder or GridView.count as data within the cards will be populated with Firebase Data.

I'm facing similar issues. It looks like theres some problem when the size of the confetti area is calculated.

@Eerey canvas: const Size(double.infinity, double.infinity), use canvas like this and this issue will resolve. canvas property of Confetti widget
