Container(
child: ListView.builder(
itemCount:
superheros_length == null ? 0 : superheros_length.length,
itemBuilder: (BuildContext context, int index) {
int Statucode =
jsonDecode(data)['DeviceList'][index]['Statucode'];
var vrStatucode = Statucode;
//algorithme for add icons status (start, move and parking)
if (vrStatucode == 61714) {
image1 = false;
image2 = false;
image3 = true;
} else if (vrStatucode >= 62465 && vrStatucode < 62466) {
image1 = false;
image3 = false;
image2 = true;
} else if (vrStatucode >= 61472) {
image1 = true;
image3 = false;
image2 = false;
}
return InkWell(
onTap: () {
// vId = jsonDecode(data)['DeviceList'][index]['Device'];
// Provider.of<APIProvider>(context, listen: false).setVId(vId);
Provider.of<APIProvider>(context, listen: false)
.setVId(jsonDecode(data)['DeviceList'][index]
['Device']);
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Maps(

[index]['Device_desc'],

just delete the getImage() methode if you don't need it. By Visibilty the icon is diplayed depending on the status code.
I'm currently writing my first Flutter App and I got a little stuck here. Basically what I'm trying to do is display an image at the top of the screen (with 100px top-margin) and display a Column which contains some Text and a Button on the centre of the screen. I tried moving mainAxisAlignment crossAxisAlignment into the outer Column Widget but that centres everything.
Here's my code:
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: Center(
child: Column(
children: [
Opacity(
opacity: 0.25,
child: Container(
child: Image.asset('assets/images/logo.png'),
margin: EdgeInsets.only(top: 100),
width: 75,
),
),
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text('Please enter your first name:'),
TextButton(onPressed: () {}, child: Text('Submit'))
],
)
],
),
),
);
You actually only need to wrap the second column in an Expanded widget, "so that the child fills the available space", that's all:
Column(
children: [
Expanded(
child: Column(
children: [],
),
)],
),
try, wrap your second Column inside a Center widget.
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: Center(
child: Column(
children: [
Opacity(
opacity: 0.25,
child: Container(
child: Image.asset('assets/images/logo.png'),
margin: EdgeInsets.only(top: 100),
width: 75,
),
),
Center(
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text('Please enter your first name:'),
TextButton(onPressed: () {}, child: Text('Submit'))
],
)
],
),
),
),
);
If this doesn't work you could also wrap it in an Align widget and add the alignment property to it.
Align(
alignment: Alignment.center,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text('Please enter your first name:'),
TextButton(onPressed: () {}, child: Text('Submit'))
],
),
),
import 'package:flutter/material.dart';
void main() {
runApp(
MaterialApp(
home: Scaffold(
appBar: AppBar(),
body: Container(
height: double.infinity,
width: double.infinity,
color: Colors.blue,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
height: 200,
width: 200,
color: Colors.pink,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
),
),
],
),
),
),
),
);
}
you have to use mainAxisAlignment property to set MainAxisAlignment.center.
In order to center align your second column,
Make sure MainAxisAlignment of your Second Column is MainAxisAlignment.center
Wrap your second column inside a Align Widget
Now, wrap your Align widget with Expanded widget.
This should solve your issue.
Check this refrence.

crossAxisAlignment: CrossAxisAlignment.start,

I'm trying to re-create layout from Gmail, but I don't know how to position icons in my layout.
Here's an Image how I want these icons to look like:
Here's an image of what I already did in Flutter:
I want the icons to have a space between them and I'd like them to be at the same level of height as "McDonald Poland".
Is there anyone, who can help me?

}
this is work! You have to put the 'M' Container inside the Row and put the icons inside a Container
return Scaffold(
body: Container(
padding: EdgeInsets.only(top: 50),
child: new Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.end,
children: [

decoration: BoxDecoration(

child: Center(
child: Text(
'M',
style: TextStyle(fontSize: 20.0),
),
)),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
children: [
Text('McDonalds Poland',
style: TextStyle(color: Colors.black)),
SizedBox(width: 8.0),
Text('Wczoraj',
style: TextStyle(color: Colors.grey))
],
),
Row(
children: [
Text('do mnie',
style: TextStyle(color: Colors.grey)),
Icon(Icons.expand_more)
],
)
],
),
],
),
Container(
padding: EdgeInsets.only(top: 50),
child: Row(
children: [
Icon(Icons.reply),
Icon(Icons.more_vert)
],
),
)
],
)
])),
);
I'm trying to create a ListView with Card widget.
I have the ListView and the Card but I can't figure out how to place widgets correctly inside the Card itself. This is how it looks now:
I want the favorites icon and the image to keep their place, but to move the text to be near the image and to have the "Jean-Paul-Gaultier" text to be closer to the "Le Male" and have it align left.
This is what I have so far:
Widget _myListView(BuildContext context) {
return ListView.builder(
itemBuilder: (context, index){
return Card(
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Image.network('${decoded[index]['image']}'),
),
],
),
SizedBox(width: 8,),
Column(
children: <Widget>[
Text(
'${decoded[index]['name']}',
style: TextStyle(
color: Colors.black87,
fontWeight: FontWeight.bold,
fontSize: 14,
),
),
Row(
children: <Widget>[
Text(
'${decoded[index]['brand']}',
style: TextStyle(
color: Colors.blueGrey,
fontWeight: FontWeight.normal,
fontSize: 12,
),
),
],
),
],
),
Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
IconButton(
icon: Icon(Icons.favorite_border),
),
],
),
],
),
);
},
);
}
Without the mainAxisAlignment: MainAxisAlignment.space-between the text is indeed closer to the image, but the favorites icon gets right near the text which is something I do not want.
I tried to search for answers but as I'm new to Flutter I don't really know the right keywords so I couldn't find anything.
A much easier approach would be using a ListTile
Widget _myListView(BuildContext context) {
return ListView.builder(
itemBuilder: (context, index) {
return Card(
child: ListTile(
title: Text("title"),
subtitle: Text("subtitle"),
leading: Container(
width: 48, height: 48,
child: Placeholder(), //place image here replacing the Placeholder widget
),
trailing: IconButton(
icon: Icon(Icons.favorite_border),
onPressed: () {},
),
),
);
},
);
}
which gives us
But if you want your code then here it is
Widget _myListView(BuildContext context) {
return ListView.builder(
itemBuilder: (context, index) {
return Card(
child: Row(
children: <Widget>[
Container(
margin: const EdgeInsets.all(8.0),
child: Placeholder(),
width: 48,
height: 48,
),
SizedBox(
width: 8,
),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'title',
style: TextStyle(
color: Colors.black87,
fontWeight: FontWeight.bold,
fontSize: 14,
),
),
Text(
'subtitle',
style: TextStyle(
color: Colors.blueGrey,
fontWeight: FontWeight.normal,
fontSize: 12,
),
),
],
),
Spacer(),
IconButton(
icon: Icon(Icons.favorite_border),
onPressed: () {},
),
],
),
);
},
);
}
EDIT
to reduce the space between title and subtitle replace the title with following code
title: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text("title",style: Theme.of(context).textTheme.body2,),
Text("subtitle",style: Theme.of(context).textTheme.caption,),
],
),
I am creating a screen like Instagram profile but mainaxisAlignment.spaceEvenly is not working. It works just fine if the row is not inside any other row or column but in this case It didn't.
