Wrap the SingleChildScrollView with a Container and add decoration

Scaffold(
resizeToAvoidBottomInset : false,
 body: Container(
  height: MediaQuery.of(context).size.height,
  width: MediaQuery.of(context).size.width,
   decoration: BoxDecoration(
     image : DecorationImage(
      image: AssetImage('imagePathHere'),
     )
   ),
    child: SingleChildScrollView(

    )
 )
)
