Flutter - BoxConstraints forces an infinite width

Question

How put orange container full width?

I'm try with double.infinity but get error BoxConstraints forces an infinite width.

    Container(
      padding: EdgeInsets.symmetric(horizontal: 20),
      height: 205,
      color: Colors.grey,
      //margin: EdgeInsets.symmetric(vertical: 20),
      child: Stack(
        children: [
          Positioned(
            left: 0,
            bottom: 0,
            child: Container(
              height: 185,
              width: 350,  //double.infinity --not working
              color: Colors.deepOrange,
            ),
          ),
          Positioned(
            right:0,
            top:0,
            child: Image.asset('assets/images/book-1.png',width: 150,),
          ),
        ],
      ),
    )

Is this container inside a `listview` or any other scrollable widget? — Amir Hossein Rahmanzadeh, Oct 04 '21 at 10:14
@AmirHosseinRahmanzadeh Scaffold > SingleChildScrollView > Column and then Contaiiner, before this Container in Column I have other Container and SizedBox — babayaro, Oct 04 '21 at 10:16
You can not have widgets with the height of infinity inside any vertical scrollable widget such as `SingleChildScrollView` — Amir Hossein Rahmanzadeh, Oct 04 '21 at 10:18
Is this `Container` code snippet inside the same file or separated one? can you include parent's details ? — Md. Yeasin Sheikh, Oct 04 '21 at 12:15

You can use MediaQuery.of(context).size.width for full screen width of Container widget.
