I want to place all row items equally in one line, exactly like what align-Item : center does in html.
My project piece is the image below, but the image is not aligned with the buttons.
And the buttons are a little higher than the picture.
And my codes :
import 'package:flutter/material.dart';
class Home extends StatelessWidget {
const Home({super.key});
#override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
children: [
Row(
children: [
Spacer(),
ElevatedButton(
onPressed: (() {}),
child: Text("Report"),
style: ElevatedButton.styleFrom(
backgroundColor: Color(0xffffb200),
foregroundColor: Color(0xff00324B)),
),
Spacer(),
ElevatedButton(
onPressed: (() {}),
child: Text("Donate"),
style: ElevatedButton.styleFrom(
backgroundColor: Color(0xffffb200),
foregroundColor: Color(0xff00324B)),
),
Spacer(),
ElevatedButton(
onPressed: (() {}),
child: Text("Adopt"),
style: ElevatedButton.styleFrom(
backgroundColor: Color(0xffffb200),
foregroundColor: Color(0xff00324B)),
),
Spacer(),
Container(
margin: EdgeInsets.fromLTRB(0, 30, 0, 10),
height: 60.0,
width: 60.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(95),
image: DecorationImage(
image: AssetImage("assets/images/download.jpg"),
fit: BoxFit.cover,
),
),
),
SizedBox(
width: 14,
)
],
),
],
),
);
}
}
I even tried mainAxisAlignment: MainAxisAlignment.center
and crossAxisAlignment: CrossAxisAlignment.center but it didn't work.
Basically, you can solve your problem by putting the following code
Row(crossAxisAlignment: CrossAxisAlignment.center)
But the problem is with your code.
If you remove the margin of the photo, the problem will be solved
margin: EdgeInsets.fromLTRB(0, 30, 0, 10),
Just remove margin: EdgeInsets.fromLTRB(0, 30, 0, 10), from your last element of Row
Container(
// margin: EdgeInsets.fromLTRB(0, 30, 0, 10),
height: 60.0,
width: 60.0,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(95),
image: DecorationImage(
image: AssetImage("assets/images/download.jpg"),
fit: BoxFit.cover,
),
),
),
you can just add in the Row`
Row(
crossAxisAlignment: CrossAxisAlignment.center,
)
You should use crossAxisAlignment to align the row. So like this
Row(crossAxisAlignment: CrossAxisAlignment.center)

The asset image is 200x200px, but when it used in leading of ListTile it's not fitted as axpected.
The rendered image looks this way. How to display it proportioanlly 90x90 as it's defined in Image height and width properties?
Card(
key: ValueKey(favorites[index]),
margin: EdgeInsets.all(20),
child: ListTile(
leading: kNoImage,
title: Text(favorites[index]),
subtitle: Text(favorites[index]),
trailing: IconButton(
icon: Icon(Icons.close),
onPressed: () {
debugPrint('entry deleted');
},
),
),
);
const kNoImage = Image(
image: AssetImage('assets/no-user-image.png'),
height: 90,
width: 90,
fit: BoxFit.cover,
);
Change the value of fit to something like BoxFit.scaleDown or BoxFit.contain to get the desired result. See the BoxFit docs to see what these values mean.
The max height for leading widget for your case is ≈56px.
So, if you want to explicitly want to keep it 90, I'd suggest you to make your own ListTile with Row() and Column() which is pretty easy.
This is what I found in ListTile(),
final Offset baseDensity = visualDensity.baseSizeAdjustment;
if (isOneLine)
return (isDense ? 48.0 : 56.0) + baseDensity.dy;
if (isTwoLine)
return (isDense ? 64.0 : 72.0) + baseDensity.dy;
return (isDense ? 76.0 : 88.0) + baseDensity.dy;
I prefer not to use ListTile because of it default behavior. Therefor, I prefer
on dartPad or on Gist
Custom ListTile

Try below code hope its help to you

The problem is solved when I delete bottom: -170.0,
But I need it in the design
I figured I can draw ripple over an image by enclosing the image in Ink(decoration: BoxDecoration(image: ...)), but how can I do the same for Text?
This is supposed to be a card with an image on top and a title and some other information at the bottom:
#override
Widget build(BuildContext context) {
final theme = Theme.of(context);
final post = _postModel.post;
return Material(
color: theme.colorScheme.background,
child: InkWell(
onTap: () {},
splashColor: Colors.red,
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10, vertical: 5),
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
if (post.imageUri != null)
// This image IS covered by the ripple (what I need)
AspectRatio(
aspectRatio: 5 / 3,
child: Ink(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(3),
image: DecorationImage(
image: NetworkImage('https://picsum.photos/700'),
fit: BoxFit.cover,
),
),
),
),
// This must be underneath the ripple, but isn't.
Text(post.title, style: theme.textTheme.headline5),
Container(
padding: EdgeInsets.symmetric(horizontal: 0, vertical: 5),
color: Colors.transparent,
height: 60,
child: Row(
children: <Widget>[
// This is also covered by the ripple
Ink(
height: 35,
width: 35,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(3),
image: DecorationImage(
fit: BoxFit.cover,
image: NetworkImage('https://picsum.photos/100'),
),
),
),
SizedBox(width: 5),
// This must be underneath the ripple but isn't
Ink(
// decoration: Decoration,
child: Text(
post.author,
style: theme.textTheme.caption,
),
),
Spacer(),
],
),
),
],
),
),
),
);
}
When I press, the ripple covers both images as expected, however, I can't figure out how to make the ripple cover the text widgets as well. I tried wrapping the text in an Ink widget (the last one), but it doesn't work - the text is still displayed over the ripple.
Unpressed:
Pressed (the text is visible):
I'm trying to make this drawing but I'm struggling.
I don't understand how to make the white block of information dynamic. That is to say that it automatically adapts to the size in height of the elements it contains.
I am for the moment obliged to give a defined height (here 200), I would like the size to be automatic. Moreover if I do not give a defined size my gray line on the left side disappears.
The design :
ListTile(
title : Column(
children: [
Container(
width: double.infinity,
child: Row(
children: [
Container(
width: 50,
alignment: Alignment.center,
child: Container(
width: 20,
height: 20,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(40),
border: Border.all(
width: 5,
color: Colors.blue,
style: BorderStyle.solid
)
),
),
),
Text('9:00 am - 9:15 am')
],
)
),
Container(
child: IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
width : 50,
alignment: Alignment.center,
child: IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(
color: Colors.grey,
width: 3,
height : 200 // if I remove the size it desappear
),
],
),
),
),
Expanded(
child: Container(
margin: EdgeInsets.symmetric(vertical :10),
padding: EdgeInsets.symmetric(vertical: 20, horizontal: 10),
color: Colors.white,
child: Column(
children: [
Text('Titre'),
Text('Info 1'),
Text('Info 2')
],
),

),
),
You can try this package for timelines https://pub.dev/packages/timeline_tile.
This package also automatically Sizes your widget height and width.
And for Automatically Sizing your widgets next time, You could use Expanded widget at most places in your code.
Note: An Expanded widget must be a descendant of a Row, Column, or Flex, So Use it carefully.
I think it's much easier with this package, timelines.
TimelineTileBuilder.connected(
connectionDirection: ConnectionDirection.before,
itemCount: processes.length,
contentsBuilder: (_, index) {
//your Container/Card Content
},
indicatorBuilder: (_, index) {
if (processes[index].isCompleted) {
return DotIndicator(
color: Color(0xff66c97f),
child: Icon(
Icons.check,
color: Colors.white,
size: 12.0,
),
);
} else {
return OutlinedDotIndicator(
borderWidth: 2.5,
);
}
},
connectorBuilder: (_, index, ___) => SolidLineConnector(
color: processes[index].isCompleted ? Color(0xff66c97f) : null,
),
),
),
I'm trying to create a circle in the flutter. I want to add multiple buttons and bound them in a circle like this.
The marked fields are supposed to be buttons and Course 1 is just the text.
I am able to create something like this but it is only string splitted in the button.
Here is my code for this. I'm not getting any idea about how to do this task. I'm new to flutter.
import 'package:flutter/material.dart';
void main(){runApp(MyApp());}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: new AppBar(
title: Text("Student home"),
),
body:Center(
child: Container(
margin: EdgeInsets.all(10),
padding: EdgeInsets.all(10),
width: 200,
height: 200,
child: Center(
child: Text("Course 1 \n Course 2",
style: TextStyle(fontSize: 12.0,
fontStyle: FontStyle.italic,
),
textAlign: TextAlign.center,
),
),
decoration: BoxDecoration(
border:Border.all(width:3),
borderRadius: BorderRadius.all(
Radius.circular(50),
),
color: Colors.yellow,
),
),
)
),
);
}
}
try shape: BoxShape.circle,,
Container(
width: 100,
height: 100,
decoration: BoxDecoration(
border: Border.all(width: 2),
shape: BoxShape.circle,
// You can use like this way or like the below line
//borderRadius: new BorderRadius.circular(30.0),
color: Colors.amber,
),
child:Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('ABC'),
Text('XYZ'),
Text('LOL'),
],
),
),
Output
is this design that you want?
it contain two button and one text widget
body: Center(
child: Container(
margin: EdgeInsets.all(10),
padding: EdgeInsets.all(10),
width: 200,
height: 200,
child: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
"Course 1",
style: TextStyle(
fontSize: 12.0,
fontStyle: FontStyle.italic,
),
textAlign: TextAlign.center,
),
MaterialButton(
onPressed: () {
//do whatever you want
},
child: Text("Mark Attendance"),
),
MaterialButton(
onPressed: () {
//do whatever you want
},
child: Text("Mark Attendance"),
),
],
),
),
decoration: BoxDecoration(
border: Border.all(width: 3),
borderRadius: BorderRadius.all(
Radius.circular(200),
),
color: Colors.yellow,
),
),
),
There are multiple ways to make the border round. As of now you are using fixed height and width always use greater number for border-radius.
For eg.
when your heigh is 200X200 use 150-200 number for border-radius.
here is the code which works fine when you have fixed height and width of the container.
Note: This works only fine when your heigh and width is fixed for the container because the padding in the code is static.If you want dynamic then please use the screen calculation techniques to make if responsive
Making any widget clickable in the Flutter.
There are a couple of Widgets available to make any widget clickable
Gesture Detector
This widget has many methods including onTap() which means you can attach a callback when the user clicks on the widget. For eg (this is used in your code)
GestureDetector(
onTap: (){}, //this is call back on tap
child: Text("Mark Attendance")
)
InkWell Widget (Note: This widget will only work when it is a child of the Material widget)
Material(
child: InkWell(
onTap: (){},
child: Text("Mark Attendance"),
),
)
Here is the working code.
import 'package:flutter/material.dart';
void main(){runApp(MyApp());}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: new AppBar(
title: Text("Student home"),
),
body:Center(
child: Container(
margin: EdgeInsets.all(10),
padding: EdgeInsets.all(10),
width: 200,
height: 200,
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(bottom:40.0,top: 20.0),
child: Text("Course 1"),
),
Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: GestureDetector(
onTap: (){},
child: Text("Mark Attendance")),
),
Padding(
padding: const EdgeInsets.all(8.0),
child:Material(
child: InkWell(
onTap: (){},
child: Text("Mark Attendance"),
),
)
),
],)
],
),
decoration: BoxDecoration(
border:Border.all(width:3),
borderRadius: BorderRadius.all(
Radius.circular(150),
),
color: Colors.yellow,
),
),
)
),
);
} }
Note: Material widget always set the background as white for the text
widget
Thanks, I hope is information was helpfull
