CircleAvatar in trailing in ListTile not centered - flutter

I can't seem to figure out how to center my CircleAvatar inside the trailing component of my ListTile. Here is my code:
static Widget buildRecordCard(MyCard card, BuildContext context) {
var dateFormat = DateFormat('MM/dd/yyyy');
return Column(
children: [
ListTile(
shape:
RoundedRectangleBorder(borderRadius: BorderRadius.circular(30)),
tileColor: Colors.white,
title: Text(
"Score: " + card.score!,
style: const TextStyle(fontSize: 38),
),
subtitle: Column(children: [
const Align(
alignment: Alignment.centerLeft,
child: Text(
"Personal Record",
style: TextStyle(fontSize: 22),
),
),
const SizedBox(height: 6),
Align(
alignment: Alignment.centerLeft,
child: Text(
dateFormat.format(card.createdOn.toDate()),
style: const TextStyle(fontSize: 18),
),
),
const SizedBox(height: 6),
]),
trailing: Container(
constraints: const BoxConstraints(minWidth: 70.0, maxWidth: 80),
height: double.infinity,
child: CircleAvatar(
radius: 35,
backgroundColor: Colors.transparent,
child: Image.asset("assets/" + card.subCategory + ".png")),
)),
const SizedBox(height: 18),
],
);
}
and here is what it is currently outputting:
I also tried to wrap my CircleAvatar in a SizedBox and in a Column with a mainAxisAlignment: MainAxisAlignment.center and it produced the same output.

You can used Transform.translate refer more about Offset
Transform.translate(
offset: Offset(0, 25),//set dy on your need
child: Container(),
),
Full Code:
trailing: Transform.translate(
offset: Offset(0, 25),
child: Container(
constraints: const BoxConstraints(minWidth: 70.0, maxWidth: 80),
height: double.infinity,
child: CircleAvatar(
radius: 35,
backgroundColor: Colors.transparent,
child: Image.network(
"https://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png",
height: 50,
),
),
),
),
Result->

You can use Row widget for this. and Use alignment: Alignment.center, on Container.
return Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Column(
children: [...],
),
Container(
constraints: const BoxConstraints(minWidth: 70.0, maxWidth: 80),
alignment: Alignment.centerRight,
child: CircleAvatar(
radius: 35,
backgroundColor: Colors.red,
....
),
),
],
);

what is equivalent of guidelines (constraint layout) in flutter?

I want to create view like image, the first view (blue view) is 30% of screen height
and the second view (red view) is center vertical of first view (15% of the first view from bottom to top, and 15% of the first view from bottom to bottom).
if in android XML constraint layout I can use guidelines to handle that, but in flutter what I can use to create like that view?

I found this code and it's good but If I try in other phone resolution the second view is not center of first view. like below image
you can play with something like this :
LayoutBuilder(
builder: (context, constraints) {
final firstHeight = constraints.biggest.height * .3;
final secondHeight = 200.0;
return SingleChildScrollView(
child: Column(
children: [
SizedBox(
height: firstHeight + secondHeight / 2,
child: Stack(
children: [
Positioned(
top: 0,
height: firstHeight,
left: 0,
right: 0,
child: Container(
color: Colors.blue,
),
),
Positioned(
top: firstHeight - secondHeight / 2,
left: 0,
height: secondHeight,
child: Container(
width: 200,
color: Colors.red,
),
),
],
),
),
Container(
height: 200,
margin: const EdgeInsets.only(
bottom: 8,
),
color: Colors.green,
),
Container(
height: 200,
margin: const EdgeInsets.only(
bottom: 8,
),
color: Colors.green,
),
Container(
height: 200,
margin: const EdgeInsets.only(
bottom: 8,
),
color: Colors.green,
),
Container(
height: 200,
margin: const EdgeInsets.only(
bottom: 8,
),
color: Colors.green,
),
],
),
);
},
)
result :
I think what you can use is wrap your image in an expanded widget and use its flex property. Flex basically ensures how much space a widget takes.So by default flex is set to 1. Hence wrap both your widgets with an expanded widget and set the flex property accordingly. I hope it solves your problem.

How to center text and prevent text from overflowing using Flutter

My UI currently looks like this:
I want to center the text in the middle of the space that is left over after the image is placed. However, I also want to make sure that my text does not overflow due to the size. How can I do that? My code is as follows:
Widget build(BuildContext context) {
return Card(
color: Theme.of(context).scaffoldBackgroundColor,
elevation: 0,
child: Column(
children: [
Divider(
thickness: 2,
color: Colors.white,
height: 0,
),
Row(
children: [
Container(
padding: EdgeInsets.all(0),
width: 100,
height: 100,
child: CircleAvatar(
radius: 50,
backgroundImage: NetworkImage(imageUrl),
),
),
Container(
padding: EdgeInsets.all(40),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(
alignment: Alignment.topCenter,
child: Text(
name,
style: TextStyle(
fontSize: 30,
color: Colors.white,
),
),
),
Container(
alignment: Alignment.bottomLeft,
padding: EdgeInsets.all(15),
child: Text(
modalityText,
style: TextStyle(
fontSize: 10,
color: Colors.white,
),
),
),
],
),
),
],
),
],
),
);
}
Here, this is one way of doing what you want
Widget build(BuildContext context) {
return Card(
color: Theme.of(context).scaffoldBackgroundColor,
elevation: 0,
child: Column(
children: [
Divider(
thickness: 2,
color: Colors.white,
height: 0,
),
Row(
children: [
Container(
padding: EdgeInsets.all(0),
width: 100,
height: 100,
child: CircleAvatar(
radius: 50,
backgroundImage: NetworkImage("imageUrl"),
),
),
Expanded(
child: Container(
padding: EdgeInsets.all(40),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
alignment: Alignment.topCenter,
child: Text(
"name",
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 30,
color: Colors.white,
),
),
),
Container(
alignment: Alignment.bottomLeft,
padding: EdgeInsets.all(15),
child: Text(
"modalityText",
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 10,
color: Colors.white,
),
),
),
],
),
),
),
],
),
],
),
);
}

What is the best flutter widget to use to achieve this kinda layout?

This is the UI I want to implement, I only started playing with flutter last week so I am not as fluent. I was wondering what is the best way to achieve this layout.
This is what I get with a stack and column:
This is the code:
Column(
children: <Widget>[
Expanded(
child: Container(
constraints: BoxConstraints.expand(height: 150),
color: Colors.blue,
child: Stack(
overflow: Overflow.visible,
children: <Widget>[
Positioned(
bottom: -40,
left: MediaQuery.of(context).size.width * 0.4,
// alignment: Alignment.bottomCenter,
child: Container(
constraints: BoxConstraints.expand(height: 80, width: 80),
color: Colors.green,
),
),
],
),
),
flex: 3,
),
Expanded(
child: Container(
margin: EdgeInsets.all(15.0),
color: Colors.red,
),
flex: 7,
)
],
);
I made something like the image you provided with dummy image and some icon you can change icons if you want,use media query size instead of fixed padding tops
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: SingleChildScrollView(
child: Column(
children: [
Stack(children: [
Container(
child: FittedBox(
fit: BoxFit.fill,
child: Image.network('https://picsum.photos/300?image=10')),
height: 150,
width: double.infinity,
),
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Padding(
padding: const EdgeInsets.only(top: 75),
child: MaterialButton(
onPressed: () {},
elevation: 2.0,
color: Colors.red,
child: Icon(
Icons.message,
size: 27.0,
),
padding: EdgeInsets.all(20),
shape: CircleBorder(),
),
),
Padding(
padding: const EdgeInsets.only(top: 75),
child: Column(children: [
CircleAvatar(
radius: 55.0,
backgroundImage:
NetworkImage('https://i.pravatar.cc/150?img=54'),
backgroundColor: Colors.transparent,
),
Text("David Beckham"),
Text("Model/SuperStar")
]),
),
Padding(
padding: const EdgeInsets.only(top: 75),
child: MaterialButton(
onPressed: () {},
elevation: 2.0,
color: Colors.blue,
child: Icon(
Icons.add,
size: 27.0,
),
padding: EdgeInsets.all(20),
shape: CircleBorder(),
),
),
],
),
]),
Container(height: 100, color: Colors.red),
Container(height: 100, color: Colors.green),
Container(height: 100, color: Colors.yellow),
Container(height: 100, color: Colors.blue),
],
)));
}
}

Flutter increase ListTile height

I want to have a list tile that has a decent sized leading image, then a description of the item and an icon.
What I am finding, despite searching for answers online, is that I am unable to increase the height of the list tile no matter what height the leading image is.
Code:
ListTile(
leading: ConstrainedBox(
constraints: BoxConstraints(
minWidth: 100,
minHeight: 260,
maxWidth: 104,
maxHeight: 264,
),
child: Image.asset('lib/images/burger_texas_angus.jpg', fit: BoxFit.fill),
),
title: Text('Texas Angus Burger'),
subtitle: Text('With fries and coke.'),
trailing: Icon(
Icons.menu,
),
onTap: () {},
onLongPress: () {},
dense: false,
),
Want it to end up looking something like this, where they have a nice big square leading icon which appears to dictate the height of the listtile, whereas everything I am doing crams the image into a narrow tile.
Ok so the answer to this is that it isn't possible. A ListTile is a very, very basic built-in widget that can only be a particular height, and there is nothing you can do about it.
If you want to do anything visually cool, with pictures etc like I have shown in my question, you have to create a custom CARD instead.
I will show my resulting code for a basic card layout that will give a similar result to the image I posted, in case anyone needs some help with this:
Container(
width: MediaQuery.of(context).size.width * 0.94,
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(0.0),
),
color: Colors.white70,
elevation: 10,
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(2.0),
child: ConstrainedBox(
constraints: BoxConstraints(
maxWidth: MediaQuery.of(context).size.width * 0.28,
maxHeight: MediaQuery.of(context).size.width * 0.28,
),
child: Image.asset(
'lib/images/burger_texas_angus.jpg',
fit: BoxFit.fill
),
),
),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Container(
width: MediaQuery.of(context).size.width * 0.5,
child: Padding(
padding: const EdgeInsets.fromLTRB(10, 10, 0, 0),
child: Text(
'Texas Angus Burger',
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 18,
),
),
),
),
Container(
width: MediaQuery.of(context).size.width * 0.5,
child: Padding(
padding: const EdgeInsets.fromLTRB(5, 10, 0, 0),
child: Text(
'100% Australian Angus grain-fed beef with cheese and pickles. Served with fries.',
style: TextStyle(
fontSize: 12,
),
),
),
),
],
),
Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(5, 40, 0, 0),
child: Text(
'\$ 24.00',
style: TextStyle(
fontSize: 14,
),
),
),
],
),
],
),
),
),
],
),
),
Try this:
Container(height: 100, child: ListTile(
title: Text("My Title"),
trailing: Icon(Icons.arrow_right),
));
you can wrap ListTile with Container and give it width and height
ListTile(
leading: Container(
height: 80,
width: 80,
child: CircleAvatar(
backgroundImage: AssetImage(
'assets/images/splash_view_images/splash.png'),
),
),
title: Text('some text'),
subtitle:
Text('some text.'),
),

Flutter how can i alien an icon in a row

My current screen,
how I want it to lock like this made manually
How can I make the line of icons alined next to the left border?
My code is:
Container(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height / 13,
alignment: AlignmentDirectional.centerStart,
child: Row(
children: <Widget>[
SizedBox(width: 25.0),
Text(
"hello world"
),
SizedBox(width: getWidth() * 185.0),
Align(
alignment: Alignment.centerLeft,
child: Icon(
Icons.check,
size: 20,
color: Colors.grey,
),
),
],
),
),
Try this way wrap your Text widget inside Expanded() widget it will work
Container(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height / 13,
alignment: AlignmentDirectional.centerStart,
child: Row(
children: <Widget>[
SizedBox(width: 25.0),
Expanded(
child: Text(
"hello world"
),
),
SizedBox(width: 20),
Align(
alignment: Alignment.centerLeft,
child: Icon(
Icons.check,
size: 20,
color: Colors.grey,
),
),
SizedBox(width: 20),
],
),
)
