I have added 'Sliver AppBar' into Scaffold of my app and I am wondering why it shows two app bars now. The Scaffold contains only one drawer but in UI , it shows two drawers. Anybody know what is going wrong.
return Scaffold( body: CustomScrollView( slivers: <Widget>[ SliverAppBar( bottom: AppBar( title: SizedBox( height: 45, child: TextField( decoration: InputDecoration( contentPadding: EdgeInsets.only(top: 5, left: 15), suffixIcon: IconButton( icon: Icon(Icons.search), onPressed: () { }, ), filled: true, fillColor: Colors.white, hintText: "What are you looking for ?", border: OutlineInputBorder( borderRadius: BorderRadius.circular(5), ), ), ), ), ), ), drawer: Drawer(), );
After removing SliverAppBar from the code, it shows blank screen. So, it is confirmed that the two AppBars are coming from above code only.
