Refresh indicator without scrollview

You must do the following:

• Use a SingleChildScrollView with the property physics set to AlwaysScrollableScrollPhysics().
• Make sure it’s child has a height of the size of the screen, which you can get with MediaQuery.of(context).size.height.

The complete example:

classs MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return RefreshIndicator(
      onRefresh: () {},
      child: SingleChildScrollView(
        physics: AlwaysScrollableScrollPhysics(),
        child: Container(
          child: Center(
            child: Text('Hello World'),
          ),
          height: MediaQuery.of(context).size.height,
        ),
      ),
    );
  }
}
