you can set image in background using BoxDecoration in container-
Container(
height: 120.0,
width: 120.0,
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage(
'imagename'),
fit: BoxFit.fill,
),
shape: BoxShape.circle,
),
)

On your Scaffold's body: you are using ListView. You can still find those widgets by scrolling down.
For your case, you like to have text and button widgets over the UI.
You need to replace ListView with Stack on body.
return Scaffold(
body: Stack( // this
children: [
CarouselSlider

flutter, how to wrap barcode and qr code in the same container?

I'm trying to make the barcode above the qrcode and I will like to make them in the same container, how should I edit it?
Thanks Alot!
body: SafeArea(
child: Center(
child: Column(
children: [
SizedBox(
height: 50,
child: SfBarcodeGenerator(
value: 'www.syncfusion.com',
),
),
Container(
decoration: BoxDecoration(
color: mFillColor,
borderRadius: BorderRadius.circular(12),
border: Border.all(color: mBorderColor, width: 1),
),
margin: const EdgeInsets.only(left: 30, right: 30),
width: double.infinity,
height: 350,
child: Padding(
padding: const EdgeInsets.all(90.0),
child: QrImage(
data: 'This is a simple QR code',
version: QrVersions.auto,
gapless: false,
),
),
),
],
),
),
),
What this code will show:
The effect that I want:
This is how you do this task. First you design a parent Container and then use a Column widget which contains two sizedBox as a children one is for barcode and second is for QrCode. Just like this
Scaffold(
body: SafeArea(
child: Container(
height: 250,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(12),
border: Border.all(color: Colors.black, width: 1),
),
margin: const EdgeInsets.all(30),
width: double.infinity,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
SizedBox(
height: 50,
child: SfBarcodeGenerator(
value: 'www.syncfusion.com',
),
),
const Text(
"2810 1102 0604 3155 4434 2047",
style: TextStyle(
color: Colors.grey,
fontWeight: FontWeight.w500,
),
),
SizedBox(
height: 150,
child: QrImage(
data: 'This is a simple QR code',
version: QrVersions.auto,
gapless: false,
),
),
const Text(
"Any text here",
style: TextStyle(
color: Colors.grey,
fontWeight: FontWeight.w500,
),
),
],
),
),
),
)

Adding an image background to home page

I am trying to add a background to my home page, however, it does not seem to be working. Any thoughts? I know how to add it per se, but unsure of how to structure it. I had received some advice to use a Stack, but I am unfamiliar with this method and the resources online are not clear.
Any advice on how to structure this would be appreciated.
Here is the background image code:
Widget build(BuildContext context) {
return DecoratedBox(
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage("assets/startbackground.jpg"),
fit: BoxFit.cover),
),
and here is the page code itself.
class MyHomePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
color: Colors.orangeAccent,
height: double.infinity,
width: double.infinity,
alignment: Alignment.bottomLeft,
child: UnconstrainedBox(
child: Padding(
padding: const EdgeInsets.only(left: 50, bottom: 50),
child: Container(
height: 400,
width: 200,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Expanded(
flex: 1,
child: Container(
child: Text(
"Text",
style: TextStyle(
fontSize: 30, fontWeight: FontWeight.w700),
textAlign: TextAlign.left,
),
color: Colors.purpleAccent,
),
),
Expanded(
flex: 3,
child: Container(
child: Text(
"Some Text",
style: TextStyle(
fontSize: 60, fontWeight: FontWeight.w700),
),
color: Colors.purpleAccent,
),
),
Expanded(
flex: 3,
child: Container(
child: Text(
"Some Text",
style: TextStyle(
fontSize: 60, fontWeight: FontWeight.w700),
),
color: Colors.teal,
),
),
Expanded(
flex: 2,
child: Padding(
padding: EdgeInsets.all(15),
child: FlatButton(
minWidth: 200,
onPressed: () {},
child: Text(
"Get Started",
style:
TextStyle(color: Color(0xff7638c9), fontSize: 15),
),
color: Colors.transparent,
shape: RoundedRectangleBorder(
side: BorderSide(color: Colors.purple),
borderRadius: BorderRadius.circular(18.0),
),
),
),
),
],
),
),
),
),
),
);
}
}
It's confusing, but we don't actually need a DecoratedBox, rather a BoxDecoration (inside your container, for the decoration: argument).
:P
Here's an example:
class BackgroundImagePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
decoration: BoxDecoration(
color: Colors.orangeAccent, // this has been moved up into BoxDeco
image: DecorationImage(
fit: BoxFit.cover,
image: NetworkImage(
'https://i.pravatar.cc/300'
)
)
),
height: double.infinity,
width: double.infinity,
... <snip> ...
If the Scaffold is a child of the background image code, than I guess the Scaffold background color is hiding the image.
Set transparent background color for the Scaffold:
Scaffold(
backgroundColor: Color.transparent,
...
This ended up working. See below.
class MyHomePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Stack(children: <Widget>[
Image.asset(
"assets/startbackground.jpg",
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
fit: BoxFit.cover,
),
Scaffold(
body: Container(
color: Colors.transparent,
height: double.infinity,
width: double.infinity,
alignment: Alignment.bottomLeft,
child: UnconstrainedBox(
child: Padding(
padding: const EdgeInsets.only(left: 50, bottom: 50),
child: Container(
height: 400,
width: 200,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Expanded(
flex: 1,
child: Container(
child: Text(
"Text",
style: TextStyle(
fontSize: 30, fontWeight: FontWeight.w700),
textAlign: TextAlign.left,
),
color: Colors.transparent,
),
),
Expanded(
flex: 3,
child: Container(
child: Text(
"Some Text",
style: TextStyle(
fontSize: 60,fontWeight: FontWeight.w700),
),
color: Colors.transparent,
),
),
Expanded(
flex: 3,
child: Container(
child: Text(
"Some Text",
style: TextStyle(
fontSize: 60, fontWeight: FontWeight.w700),
),
color: Colors.transparent,
),
),
Expanded(
flex: 2,
child: Padding(
padding: EdgeInsets.all(15),
child: FlatButton(
minWidth: 200,
onPressed: () {},
child: Text(
"Get Started",
style: TextStyle(
color: Color(0xff7638c9), fontSize: 15),
),
color: Colors.transparent,
shape: RoundedRectangleBorder(
side: BorderSide(color: Colors.purple),
borderRadius: BorderRadius.circular(18.0),

Flutter Layout :- how to build this layout

I want to align the text to the center inside the image as shown in the image.
I recently started working with flutter please help me to achieve the layout.
Container(
width: MediaQuery.of(context).size.width,
margin: EdgeInsets.fromLTRB(24, 20, 24, 0),
child: Stack(
children: <Widget>[
ClipRRect(
borderRadius: BorderRadius.circular(16.0),
child: Image.asset(
'assets/images/car.jpg',
fit: BoxFit.cover,
),
),
Positioned.fill(
child: Align(
alignment: Alignment.center,
child: Text(
'Cars',
style: TextStyle(
fontFamily: 'Welcome',
fontSize: 30,
color: Colors.white),
),
),
)
],
),
)
With the help of the above code, the text is appearing in the bottom-center instead of the center.
return Container(
width: MediaQuery
.of(context)
.size
.width,
margin: EdgeInsets.fromLTRB(24, 20, 24, 0),
child: Stack(
alignment: Alignment.center,
children: <Widget>[
ClipRRect(
borderRadius: BorderRadius.circular(16.0),
child: Image.asset(
Images.image1,
fit: BoxFit.cover,
),
),
Text(
'Cars',
style: TextStyle(
fontFamily: 'Welcome',
fontSize: 30,
color: Colors.white),
)
],
),
);
