Allow overflow container more than screen-CodePudding

I have AnimatedContainer inside a Stack widget. I want to change the scale of the MyAnimatedContainer and make it bigger than screen, like image below :

How can I do that ?

Code:

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        fit: StackFit.expand,
        children: [            
          AnimatedContainer(
            height: _width,
            width: _height,
            duration: const Duration(milliseconds: 500),
            child: Image.asset('assets/Asset 2.png'),
          ),
        ],
      ),
    );
  }

I try to change width/height but it doesn't work.

CodePudding user response：

The constraints passed into theStack from its parent are tightened using stackfit.expand, So I want you to use stackfit.loose and than change the width and height . Just try if it works for you.

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        fit: StackFit.loose,
        children: [            
          AnimatedContainer(
            height: _width,
            width: _height,
            duration: const Duration(milliseconds: 500),
            child: Image.asset('assets/Asset 2.png'),
          ),
        ],
      ),
    );
  }
