I'm a student learning flutter. How do I add multiple containers to my flutter code. as shown in the right side picture. I was tried multiple times but alignments went wrong. can someone tell me where do I start to add another container set? I want to add 5 containers that display with xs, s, m,l, xl sizes texts. can someone explain how to do this?
import 'package:flutter/material.dart';
class DetailsScreen extends StatelessWidget {
const DetailsScreen({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,

Result screen->
In your case, since none of the widgets overlap, you find it easier to use Row and Column Widget. These widgets allow you to add and arrange multiple child widgets. For example, to lay out the sizes:
Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
//ADD YOUR SIZES HERE
//e.g., Text('XS'), Text('S')...
],
)
I strongly recommend you start by reading the layout guide for flutter. There is a section that answers your question directly titled laying out multiple widgets.
Good to see that you are trying to make it on your own. I see that you are already using a Column widget, so putting the sizes in shouldn't be much of a problem for you.
To put Container widgets next to each other, use a Row widget, explained here: https://api.flutter.dev/flutter/widgets/Row-class.html
Use Row() and Column() for arrangements item in the row and column.
I'm trying to make the whole OrderScreen slide up when the keyboard appears as I do in UserProfileScreen by wrapping the scaffold's container in a SingleChildScrollView, but doing so on this screen it throws various RenderBox was not laid out: _RenderScrollSemantics#abc84 relayoutBoundary=up4 NEEDS-PAINT errors, which are not thrown without SingleChildScrollView. I set up the two screen just the same apart from UserProfileScreen having a Column as a child of another Column. All column's children are wrapped in and Expanded widget with different flex values for layout purposes. Can you se why I do get these errors?

Adding height and width to the container got rid of the error, but the view doesn't slide up as UserProfileScreen instead does..with or without resizeToAvoidBottomInset: true, set in Scaffold.. the keyboard just covers up the screen..
child: Scaffold(
resizeToAvoidBottomInset: true,
body: SingleChildScrollView(
child: Container(
height: MediaQuery.of(context).size.height-50,
width: MediaQuery.of(context).size.width,
color: Colors.black54,
padding: const EdgeInsets.symmetric(vertical: 20, horizontal: 20),
child: Column(
So I have two different behaviours.
UserProfileScreen doesn't need Container's heigh and width and it slides up on keyboard appearing.
OrderScreen does need Container's height and width but doesn't slide up on keyboard appearing.
I have one main screen and I want to import another widget which contains 3 buttons. However, the widget is not showing in the main screen.
Code from main file:
Padding(
padding: EdgeInsets.only(left: 40.0),
child: Row(
children: <Widget>[
Text('Your',
style: TextStyle(color: Colors.white, fontSize: 25.0)),
SizedBox(
width: 10.0,
),
Text('Invoice',
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.bold,
fontSize: 25.0))
],
)),
SizedBox(height: 40.0),
Container(
height: MediaQuery.of(context).size.height - 185.0,
decoration: BoxDecoration(
color: Colors.white,
borderRadius:
BorderRadius.only(topLeft: Radius.circular(75.0))),
child: ListView(
primary: false,
padding: EdgeInsets.only(left: 25.0, right: 20.0),
children: <Widget>[
Padding(
padding: EdgeInsets.only(top: 45.0),
child: Container(
height: MediaQuery.of(context).size.height - 300.0,
child: ListView(
children: [
buildInvoice(
'Rent one month', 'July rent', '800€')
],
)))
])),
Expanded(
child: ButtonsDetailInvoice(),
),
],
),
);
}
Code from the buttons widget:
return Container(
height: 450.0,
// margin: const EdgeInsets.all(20.0),
child: Row(
children: [
RaisedButton(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: colorBlau)),
onPressed: () {},
color: colorBlau,
textColor: Colors.white,
child: Row(
children: <Widget>[
Icon(Icons.file_download),
Text('Download', style: TextStyle(fontSize: 15.0))
],
),
),
RaisedButton(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: colorMint)),
onPressed: () {},
color: colorMint,
textColor: Colors.white,
child: Row(
children: <Widget>[
Icon(Icons.share),
Text('Share', style: TextStyle(fontSize: 15.0))
],

onPressed: () {},
color: colorRed,
textColor: Colors.white,
child: Text('Report a Problem', style: TextStyle(fontSize: 15.0)),
),
],
),
);
}
}
I would like to see the buttons on the bottom of the main file. I imported them but they are not showing. If someone can help see the error I would really appreciate it.
Use Stack widget in main file.
I developed a login screen in which first i get the render flex error when i open the keyboard so for that i wrap my widgets in SingleChildScrollView, but after that mainAxisAlignment of Column is not working but when i removed SingleChildScrollView then everything working fine except render flex error. i don't know what to do kindly help please.

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.
I am trying to create an alert dialog with rounded corners in Flutter same as below screenshot. also add my code here, but my output is exactly different from the expected one. anyone, please help me.

The output of the code snippet looks like this:
The container where you set the BoxDecoration is in the widget tree under the alert dialog. Which means you are setting just a box within the padding of your Dialog. You need to create a custom AlertDialog/showDialog and set the radius there. In the custom widget you also add the button and everything where you need to work beyond that padding.
When you include the customShowDialog.dart file in your project (gist.github.com) where you can edit the radius here borderRadius: BorderRadius.all(Radius.circular(20.0)) and call it like this:
return new CustomAlertDialog(
content: new Container(
width: 260.0,
height: 230.0,
decoration: new BoxDecoration(
shape: BoxShape.rectangle,
color: const Color(0xFFFFFF),
borderRadius:
new BorderRadius.all(new Radius.circular(32.0)),
),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
// dialog top
new Expanded(
child: new Row(
children: <Widget>[
new Container(
// padding: new EdgeInsets.all(10.0),
decoration: new BoxDecoration(
color: Colors.white,
),
child: new Text(
'Rate',
style: TextStyle(
color: Colors.black,
fontSize: 18.0,
fontFamily: 'helvetica_neue_light',
),
textAlign: TextAlign.center,
),
),
],
),
),
// dialog centre
new Expanded(
child: new Container(
child: new TextField(
decoration: new InputDecoration(
border: InputBorder.none,
filled: false,
contentPadding: new EdgeInsets.only(
left: 10.0,
top: 10.0,
bottom: 10.0,
right: 10.0),
hintText: ' add review',
hintStyle: new TextStyle(
color: Colors.grey.shade500,
fontSize: 12.0,
fontFamily: 'helvetica_neue_light',
),
),
)),
flex: 2,
),
// dialog bottom
new Expanded(
child: new Container(
padding: new EdgeInsets.all(16.0),
decoration: new BoxDecoration(
color: const Color(0xFF33b17c),
),
child: new Text(
'Rate product',
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
fontFamily: 'helvetica_neue_light',
),
textAlign: TextAlign.center,
),
),
),
],
),
),
);
});
You will get something like this:
EDIT:
Although Flutter lately introduced the shape property which would help you with the rounded corners by setting a ShapeBorder with e.g.
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(20.0))
),
you would still need to quickly add a custom widget for some customizations, like custom padding, as stated above.
This worked for me:
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(32.0))),
Try this code :
AlertDialog(
shape: RoundedRectangleBorder(borderRadius:
BorderRadius.all(Radius.circular(15))),
title: Text('Your title!'),
content: Container(),
);
add
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.all(Radius.circular(10.0))),
title: Text("Loading..."),
content: CircularProgressIndicator(),
);
},
);
Try this code
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10.0),
),
title: Text('title'),
content: Text('content'),
);
},
);
You can simply use shape property of AlertDialog
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(16)))
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(20)),
This line of code will make alert dialog with rounded corner.
Use like this
AlertDialog(
shape:RoundedRectangleBorder(
borderRadius:BorderRadius.circular(10.0,),
),
content: yourContent()
);
Try this code
Theme(
data: Theme.of(context).copyWith(
dialogTheme: DialogTheme(
backgroundColor: Theme.of(context).cardColor,
shape: RoundedRectangleBorder(
borderRadius: radius(6),
),
),
),
child: AlertDialog()
I was looking at these answers and none of them helped me achieve the desired look.
I noticed that there was a default padding so all I did was:
AlertDialog(
titlePadding: EdgeInsets.all(0),
title: Container(
height: 30.00,
width: 300.00,
decoration: BoxDecoration(
color: Colors.redAccent,
borderRadius: BorderRadius.only(topLeft: Radius.circular(32), topRight: Radius.circular(32)),
),
),
)
I overrode the titlePadding attribute and it came just right. There is also a contentPadding attribute if you find any trouble with that. I copied this from one of my apps just to show the attribute, but it is applicable to this case as well.
If you want to use the standard Dialog you can just apply a Decoration to the Container that matches your Dialog settings
showDialog(
context: context,
child: Dialog(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10)),
child: Column(
children: <Widget>[
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(topLeft: Radius.circular(10), topRight: Radius.circular(10)),
),
child: Text('foobar'),
)
],
),
),
);
To change the appearance of the shape of the dialog, you can set the shape property of the AlertDialog to the desired shape.
AlertDialog default shape is a RoundedRectangleBorder with a radius of 4.0
AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(32.0),
),
)
AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(
Radius.circular(12.0))),
contentPadding: EdgeInsets.only(top: 10.0),
