SingleChildScrollView is not working in Flutter. What to do?

Replace

body: SingleChildScrollView(
child: Container(),
),

By

body: ScrollConfiguration(
behavior: ScrollBehavior()
..buildViewportChrome(context, null, AxisDirection.down),
child: SingleChildScrollView(
child: Container(
height: MediaQuery.of(context).size.height,
),
),
),

Make sure , you are using ScrollConfiguration in a stateful widget.

And you are Done!
