Answer 1

Use LayoutBuilder and Get the output you want

Wrap the SingleChildScrollView with LayoutBuilder and implement the Builder function.

we can use a LayoutBuilder to get the box contains or the amount of space available.

LayoutBuilder(
    builder: (BuildContext context, BoxConstraints constraints){
      return SingleChildScrollView(
        child: Stack(
          children: [
            Container(
              height: constraints.maxHeight,
            ),
            topTitle(context),
            middleView(context),
            bottomView(context),
          ],
        ),
      );
    }
)
