I wan to make this container and I have try it making in container by dividing it in 2 row. After that I divide first row in 3 row again but It was not same design made. So, please help me to make this.
Take a look at https://medium.com/flutter-community/flutter-layout-cheat-sheet-5363348d037e. It's great tutorial for Flutter layout positioning. Have fun!
import 'package:flutter/material.dart';
const Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData.dark().copyWith(
scaffoldBackgroundColor: darkBlue,
),
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
width: 300,
height: 150,
padding: const EdgeInsets.symmetric(horizontal: 15.0, vertical: 5.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20.0),
color: const Color(0xff272830),
),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
header(),
const Text(
'To register, fill out the form in the sign-up section above. In order to activate your account, we will send you an invitation email that you must confirm'),
],
),
);
}
Widget header() {
return Row(mainAxisAlignment: MainAxisAlignment.spaceBetween, children: [
Row(mainAxisSize: MainAxisSize.min, children: [
ClipOval(
child: Image.network(
'https://dt2sdf0db8zob.cloudfront.net/wp-content/uploads/2019/12/9-Best-Online-Avatars-and-How-to-Make-Your-Own-for-Free-image1-5.png',
width: 40,
height: 40,
fit: BoxFit.cover,
),
),
const SizedBox(width: 5),
Text('SIGN UP'),
]),
SizedBox(
height: 40,
child: OutlinedButton(
onPressed: () {},
child: const Text('Step 1',
style: TextStyle(
color: Colors.white,
)),
style: OutlinedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10),
),
),
),
)
]);
}
}
Try this
Column(
children: [
Container(
margin: EdgeInsets.fromLTRB(12, 12, 12, 12),
padding: EdgeInsets.fromLTRB(12, 12, 12, 12),
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.all(
Radius.circular(20),
)),
child: Column(
children: [
Row(
children: [
CircleAvatar(
backgroundImage: NetworkImage(
'https://picsum.photos/id/237/200/300'),
),
SizedBox(
width: 20,
),
Expanded(
child: Text(
"SIGN UP",
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.bold),
),
),
Container(
padding: EdgeInsets.fromLTRB(24, 12, 24, 12),
decoration: BoxDecoration(
color: Colors.grey,
border: Border.all(
color: Colors.white,
),
borderRadius: BorderRadius.all(
Radius.circular(16),
)),
child: Text("Step 1"),
),
],
),
SizedBox(
height: 8,
),
Container(
child: Text(
"To register, fill out the form in the sign-up section above. In order to activate your account, we will send you and activation email that you must confirm"),
),
],
),
)
],
),
Instead of container, you can do it by using Card. Take a look at this example from https://api.flutter.dev/flutter/material/Card-class.html
Card(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
const ListTile(
leading: Icon(Icons.album),
title: Text('The Enchanted Nightingale'),
subtitle: Text('Music by Julie Gable. Lyrics by Sidney Stein.'),
),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
TextButton(
child: const Text('BUY TICKETS'),
onPressed: () {/* ... */},
),
const SizedBox(width: 8),
TextButton(
child: const Text('LISTEN'),
onPressed: () {/* ... */},
),
const SizedBox(width: 8),
],
),
],
),
),
I need help on how to achive binding items from the list view into other widget. For example, I have a listview of Products to be sold, when a sale person click any product from the list, it should be added on top of the screen with it price, then more product can be added each time a sale person press new product from the listview. I have already tried different ways to achieve this. This is a sample of the screen I want to achieve.
This is what I have achieved so far

Here i manage to do this using the below code hope it will work for you

#override

print('List length is ${ShoppingItems.length}');

return Scaffold(

itemBuilder: (context, index) {
return ListTile(
onTap: (){
PurchasedItem.add(ShoppingItems[index]);
setState(() {
});
},

I have design that shows flash offers count but when i tried to design like the following image the alignment of widgets do not work properly. How do i approach this design? I have tried many codes but i am not getting the desired results.
The design i am trying to create
The design i did so far
Code
Widget FlashOffers(){
return GestureDetector(
onTap: (){
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => FlashOfferListScreen(),
),
);
},
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Stack(
children: [
Container(
height: 50,
width:350,
decoration: new BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.all(Radius.circular(15))
),
),
Center(child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Flash Offers",style: TextStyle(fontSize: 18,color: Colors.white,fontWeight: FontWeight.bold),),
)),
Row(
// crossAxisAlignment: CrossAxisAlignment.end,
mainAxisAlignment: MainAxisAlignment.end,
children: [
Stack(
children: [
SvgPicture.asset("assets/images/YELLOW.svg"),
Text("3")
],
),
],),
],
),
),
);
}
Try this: Remove your row widget and add alignment: Alignment.center to stack that is in the row. Wrap you Stack with Align Widget and add alignment: Alignment.centerRight
Widget flashOffers() {
return GestureDetector(
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Container(),
),
);
},
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Stack(
children: [
Container(
height: 50,
width: 350,
decoration: new BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.all(Radius.circular(15))),
),
Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text(
"Flash Offers",
style: TextStyle(
fontSize: 18,
color: Colors.white,
fontWeight: FontWeight.bold),
),
)),
Align(
alignment: Alignment.centerRight,
child: Stack(
alignment: Alignment.center,
children: [
SvgPicture.asset("assets/images/YELLOW.svg"),
Text("3")
],
),
),
],
),
),
);
}
You should consider adding the label and counter icon inside the container widget.
Your code should look something like this:
Widget flashOffers() {
return GestureDetector(
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => FlashOfferListScreen(),
),
);
},
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
height: 50,
width: 350,
padding: EdgeInsets.symmetric(horizontal: 16),
decoration: new BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.all(Radius.circular(15))),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Expanded(
child: Container(
alignment: Alignment.center,
padding: const EdgeInsets.all(8.0),
child: Text(
"Flash Offers",
style: TextStyle(
fontSize: 18,
color: Colors.white,
fontWeight: FontWeight.bold),
),
),
),
Stack(
alignment: Alignment.center,
children: [
SvgPicture.asset("assets/images/YELLOW.svg"),
Text("3"),
],
)
],
),
),
),
);
}
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
body: SafeArea(
child: Center(
child: flashOffers(),
),
),
),
);
}
Widget flashOffers() {
return GestureDetector(
onTap: () {
print('new route push');
},
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Container(
width: 350,
padding: EdgeInsets.all(15),
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [
Color(0xFFc1202e),
Color(0xFFea2127),
],
begin: Alignment.topRight,
end: Alignment.bottomLeft,
),
borderRadius: BorderRadius.all(
Radius.circular(30),
),
boxShadow: [
BoxShadow(
blurRadius: 10,
offset: Offset(-10, 10),
color: Colors.black26,
),
]),
child: Row(
children: [
Expanded(
child: Text(
"Flash Offers".toUpperCase(),
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 18,
color: Colors.white,
fontWeight: FontWeight.bold,
),
),
),
Stack(
alignment: Alignment.center,
children: [
Icon(
Icons.folder,
size: 30,
color: Colors.yellowAccent,
),
Text(
'3',
style: TextStyle(color: Colors.red),
),
],
),
SizedBox(width: 10),
],
),
),
),
);
}
}
Here is the example without using Stack. Hope you will get the idea and it will help :-)
return MaterialButton(elevation: 8,
color: Colors.redAccent,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(16.0)
),
child: Row(children: [
Expanded(child: Text('FLASH OFFER', textAlign: TextAlign.center)),
CircleAvatar(
backgroundColor: Colors.yellow, radius: 12, child: Text("2"))
]),
onPressed: () {
print('button pressed');
});
Edit: To show the shadow, use the elevation property of button. You can also change the shadow color
You can use positioned,it is so useful in stack widget.
Look at this:
https://medium.com/codespace69/flutter-widget-positioning-eca4fea1528b#:~:text=A%20Stack%20allows%20you%20to,the%20children%20of%20a%20stack.
Try this
Container(
height: 50,
width: MediaQuery.of(context).size.width * 0.65,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15.0),
),
child: FlatButton(
splashColor: iconButton,
shape: RoundedRectangleBorder(
borderRadius:
BorderRadiusDirectional.circular(20)),
color: primaryColor,
onPressed: () {
sendMail();
},
child: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Container(),
Text(
"Send",
style: styleText(
size: 20,
weight: FontWeight.bold,
color: white),
),
Container(
child: Center(
child: SvgPicture.asset(
ic_profileWhite,
height: 20,
width: 20,
),
),
),
],
),
),
),
),

You can use stack like this:
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final double heightOfFirstContainer = 100.0;
#override
Widget build(BuildContext context) {
return SafeArea(

SizedBox(

You can try this code blocks
CustomScrollView(
scrollDirection: Axis.vertical,
slivers: [
SliverFillRemaining(
hasScrollBody: false,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Text('test'),
for (int i = 0; i < 10; i++) const FlutterLogo(size: 80)
],
),
),
],
),
After wrapping Column with SingleChildScrollView wrap it with Center widget.
Set the alignment of the outer container, then wrap the column with singleChildScrollView.
Container(
alignment: Alignment.center, //Set container alignment then wrap the column with singleChildScrollView
child: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: []
),
);
Yeah MainAxisAlignment' property of a 'Column' does not work when you wrap the 'Column' in 'SingleChildScrollView'. I dont know the reason, but thats how it is.
I use 'SizedBox(height: xx)' to give space between widgets inside the 'Column' when i absolutely need a scroll view, otherwise i tend not to use the 'SingleChildScrollView'.
you can Column wrap with a Container...

This will work...
Set the alignment of the outer container as alignment.bottomCenter, then wrap the column with singleChildScrollView. It will definitely works. Thankyou.
