Alignment does not work

[Eerey]

I tried to wrap it around Align-Widgets - the children, the parent, everything.
It never works consistently.
I also tried to put the ConfettiWidget in a Stack with a fixed size (Container wrapped around it) -> It does not align correctly.
Sometimes the ConfettiWidget only emits from a singular point and every single confetti is displayed in its untransformed (and untranslated) form.
Is there some tricky behaviour underlying?

Hi! Can you share some example code, or explain better what you're trying to do? The main example demonstrates different alignments

I'm also having the same issue; I've simply copied from the example but not sure what's missing. Confettis are shooting from a single point but can't move around the screen.

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        Align(
          alignment: Alignment.center,
          child: ConfettiWidget(
            confettiController: _confettiController,
            shouldLoop:
                true, // start again as soon as the animation is finished
            colors: const [
              Colors.green,
              Colors.blue,
              Colors.pink,
              Colors.orange,
              Colors.purple
            ], // manually specify the colors to be used
          ),
        ),

Also having the same problem. All confettis are stuck in place.

edit: Center seems to be working better. Or if you want to align it to some edge, aligning it with column and/or row seems to be working.

e2: Align seems to be working fine if you just set canvas: Size.infinite to ConfettiWidget.

When I set the canvas: Size.infinite some exceptions happened
