How can I customise the flexibleSpace property in SliverAppBar in Flutter?
Instead of using FlexibleSpaceBar in the flexibleSpace property of SliverAppBar I want to use a custom widget tree, when expanded, but upon scrolling, I want to display a custom text, and not the widget tree.
I have created a custom widget tree which shall be assigned to the flexibleSpace property, but I don't know how to display custom text on scrolling, and hide the widget tree.
SliverAppBar(
expandedHeight: 180.0,
backgroundColor: const Color(0xFF9e0118),
iconTheme: IconThemeData(color: Colors.white),
floating: true,
pinned: true,
flexibleSpace: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
margin: EdgeInsets.only(top: 16.0),
padding: EdgeInsets.only(left: 32.0, right: 32.0),
child: Text(
'Some text',
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontFamily: 'PlayfairDisplay',
fontStyle: FontStyle.italic,
fontSize: 16.0),
)),
Container(
margin: EdgeInsets.only(top: 16.0),
padding: EdgeInsets.only(left: 32.0, right: 32.0),
child: Text(
'some text',
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontFamily: 'PlayfairDisplay',
fontSize: 16.0),
)),
],

You may want to wrap your widget tree inside a FlexibleSpaceBar
widget and add your widget tree as background. I hope I understood your question right. Check this gif.

backgroundColor: const Color(0xFF9e0118),
iconTheme: IconThemeData(color: Colors.white),

collapseMode: CollapseMode.pin,
centerTitle: true,
background: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
margin: EdgeInsets.only(top: 16.0),
padding: EdgeInsets.only(left: 32.0, right: 32.0),
child: Text(
'Some text',
textAlign: TextAlign.center,
style: TextStyle(

Thank you. This solves a part of my problem which is that I can hide my custom widget tree on scrolling. The second part is that I also want to be able to display some text on the app bar while its pinned, and the user is scrolling, currently, its just blank with the red background.
