CodePudding user response：

When you are using stack Widget than it means that you are overlapping your Parent widget , so in your case you are not able to get the appropriate width due to your parents widget but when you use stack Container get enough space since it is overlapping .

Try below code, Wrap your Container inside UnconstrainedBox()

Use Row Widget. Works for me :)

ListView(
          children: <Widget>[
            Row(
              children: [
                Container(
                  height: 50,
                  width: 100,
                  color: Colors.amber[600],
                  child: const Center(child: Text('Entry A')),
                )
              ],
            )
          ],
        )
