#kriti sharma for background image inside the Stack widget kindly use Positoned widget on top of the Stack widget.
example:-
children: <Widget>[
Positioned(
top: 0,
right: 0,
child: Image.asset(
"assets/icons/categories/map.jpg",
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height,
),
),
// _buildGoogleMap(context),
// _zoomminusfunction(),
// _zoomplusfunction(),
// _buildContainer(),
],
),

Actually it not black screen you got error like,
Exception caught by rendering library
The following
assertion was thrown during performResize():
Vertical viewport was given unbounded height.
I just added scrollDirection and shrinkWrap in you list.
ListView(
scrollDirection: Axis.vertical,
shrinkWrap: true,
Your whole code
home: ListView(children: <Widget>[
new Stack(
children: <Widget>[
Container(child: Text("Hello")),
Stack(
children: <Widget>[
Container(
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
color: Colors.blue,
image: DecorationImage(
image: new NetworkImage(
"https://thumbs.dreamstime.com/b/funny-face-baby-27701492.jpg"),
fit: BoxFit.fill)),
),
/*************this is the main background image****************/
Padding(
padding: EdgeInsets.only(top: 100),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
ListView(
scrollDirection: Axis.vertical,
shrinkWrap: true,
padding: const EdgeInsets.all(8),
children: <Widget>[
Center(
child: Text(
'Beneficiary Details',
style:
TextStyle(fontSize: 14, color: Colors.black),
)),
Center(

I correct it by placing ListView inside container
home: ListView(children: <Widget>[
new Stack(
children: <Widget>[
Container(child: Text("Hello")),
Stack(
children: <Widget>[
Container(
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
color: Colors.blue,
image: DecorationImage(
image: new NetworkImage(
"https://thumbs.dreamstime.com/b/funny-face-baby-27701492.jpg"),
fit: BoxFit.fill)),
),
/*************this is the main background image****************/
Padding(
padding: EdgeInsets.only(top: 100),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Conatiner( /************This container will wrap the listview and will make it scrollable also *******/
height:200,
child: ListView(
scrollDirection: Axis.vertical,
shrinkWrap: true,
padding: const EdgeInsets.all(8),
children: <Widget>[
Center(
child: Text(
'Beneficiary Details',
