Flutter: Widgets in Row are not aligned

Flutter: Widgets in Row are not aligned - android

I use row widget with two widgets inside, a text widget and iconbutton but iconbutton is not aligned with text and I don't know how to do it. This is a screenshot to show you
Row(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: widgets[index],
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {
setState(() {
widgets.remove(widgets[index]);
}),
})
],
),

Use mainAxisSize: MainAxisSize.min,
Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.grey, width: 1),
borderRadius: BorderRadius.all(Radius.circular(8.0))),
child: Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: Text(
'Theo',
style:
TextStyle(color: Colors.deepOrangeAccent, fontSize: 20),
),
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {})
],
),
),
Output:

replace CrossAxisAlignment.start with CrossAxisAlignment.baseline and add textBaseline: TextBaseline.alphabetic like this:
Row(
mainAxisSize: MainAxisSize.min,
textBaseline: TextBaseline.alphabetic,
crossAxisAlignment: CrossAxisAlignment.baseline,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(left: 10),
child: widgets[index],
),
IconButton(
icon: Icon(
Icons.close,
size: 25,
color: Colors.grey,
),
onPressed: () => {
setState(() {
widgets.remove(widgets[index]);
}),
})
],
),
You may need this to confirm:

I used InkWell instead of iconbutton and it works

How to vertically expand container widget in flutter

trying to expand Expanded or Container vertically to match its height with Row widget height, here is my code
#override
Widget build(BuildContext context) {
return InkWell(
onTap: ()=> onDepartClicked(),
child: Container(
padding: EdgeInsets.all(16),
child: Card(
child: Row(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Expanded(
flex: 8,
child: Padding(
padding: EdgeInsets.all(16),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(department.name,
overflow: TextOverflow.visible,
style: TextStyle(fontSize: 20),
),
Container(
margin: EdgeInsets.only(top: 8),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Image.asset("assets/images/feedback.png", width: 20, height: 20,),
SizedBox(width: 4,),
Text(department.phone),
SizedBox(width: 16,),
Image.asset("assets/images/feedback.png", width: 20, height: 20,),
SizedBox(width: 4,),
Text(department.type),
],
),
),
Container(margin: EdgeInsets.symmetric(vertical: 8),child: Divider(height: 0.3, color: Colors.grey,)),
Container(
child: Text(department.description,
maxLines: 3,
style: TextStyle(fontSize: 13),
),
)
],
),
),
),
Container(
width: 40,
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.only(topRight: Radius.circular(4), bottomRight: Radius.circular(4))
),
child: Column(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Image.asset("assets/images/feedback.png",
width: 20,
height: 20,
fit: BoxFit.scaleDown,
),
],
),
),
],
),
),
),
);
}
I want to expand this block in the above code (second child of the Row):
Container(
width: 40,
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.only(topRight: Radius.circular(4), bottomRight: Radius.circular(4))
),
child: Column(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Image.asset("assets/images/feedback.png",
width: 20,
height: 20,
fit: BoxFit.scaleDown,
),
],
),
),
I want to achieve this view with blue area expanded vertically in parent

Edit after more clarification on the question:
The idea behind the code below is like the This Image.
Left child of the row contains a column, the column has 3 children.
The first child of the column is the title, second one is a Row of phone and type and the last one is the description.
For "phone" and "type" you can use ListTile but you should put them on something like Flexible or define size for them.
I deinded a Listview and put 10 card inside it.
Here is the code:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: ListView.builder(
padding: EdgeInsets.all(16.0),
itemBuilder: (BuildContext context, int index) {
return _card();
},
shrinkWrap: true,
itemCount: 10,
),
),
);
}
Widget _card() {
return Card(
child: Padding(
padding: EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Flexible(
fit: FlexFit.tight,
flex: 5,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'UBIT',
overflow: TextOverflow.visible,
style: TextStyle(fontSize: 20),
),
Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Icon(Icons.message),
SizedBox(width: 4),
Text('+09210000000'),
SizedBox(width: 16),
Icon(Icons.message),
SizedBox(width: 4),
Text('Science'),
],
),
Divider(),
Text(
'Lorem Ipsum ist ein einfacher Demo-Text für ' +
'die Print- und Schriftindustrie. Lorem Ipsum ' +
'ist in der Industrie bereits der Standard Demo-Text' +
' seit 1500',
textAlign: TextAlign.justify,
),
],
),
),
Padding(
padding: EdgeInsets.only(left: 8.0),
child: Icon(
Icons.message,
size: 30.0,
),
),
],
),
),
);
}
}

Wrap the Container in a SizedBox with height:double.infinity to make it take all the available space, in your case the height of the row.
Expanded(
child: SizedBox(
height:double.infinity,
child:Container(
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.only(topRight: Radius.circular(4), bottomRight: Radius.circular(4))
),
child: Image.asset("assets/images/feedback.png", width: 20, height: 20, fit: BoxFit.scaleDown,),
),
),
)

Remove space between two Column in Flutter

I want to remove the gap between these two columns.
How can I achieve this?
This is the code which I tried. The Expanded() here is inside the Row() widget.
I would like to decrease the gap between the two Columns(). I tried wrapping both Columns inside a Container and implementing Padding on it, but it doesn't work. I tried mainAxisAlignment also.
Expanded(
child: Column(
children: <Widget>[
Container(
width: 98.0,
child: Card(
child: ListTile(
title: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'Room 1',
style: TextStyle(
fontWeight: FontWeight.bold,
),
),
],
),
subtitle: Padding(
padding: const EdgeInsets.only(top:8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Icon(
Icons.check_box_outline_blank
),
Icon(
Icons.check_box,
)
],
),
),
),
),
),
],
),
),
Expanded(
child: Column(
children: <Widget>[
Container(
width: 98.0,
child: Card(
child: ListTile(
title: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'Room 1',
style: TextStyle(
fontWeight: FontWeight.bold,
),
),
],
),
subtitle: Padding(
padding: const EdgeInsets.only(top:8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Icon(
Icons.check_box_outline_blank
),
Icon(
Icons.check_box,
)
],
),
),
),
),
),
],
),
)

The issue was solved by using Flexible() instead of Expanded().

}
I'm getting this
and I'm trying to achieve this
and this

You just need to add the following line in your code :
crossAxisAlignment: CrossAxisAlignment.start
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.start,

There is a property name cross-axis alignment for both Row and Column
As I see you have used main axis alignment.
Main Axis for Column is to align children Vertically.
Main Axis for Row is to align children Horizontally.
Cross Axis for Column is to align children Horizontally.
Cross Axis for Row is to align children Vertically.
So you can try with this for your row
crossAxisAlignment: CrossAxisAlignment.start,

Custom toolbar with background shape and back button

I'm making custom toolbar with background shape but my back button is getting correct the alignment to the text
Widget _toolBar(String headerText){
return Container(
decoration: BoxDecoration(
color: MyColors.greenHeader,
borderRadius: new BorderRadius.only(
bottomLeft: const Radius.circular(15.0),
bottomRight: const Radius.circular(15.0))
),
child:Center(child: Stack(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 1,
child:Text(headerText,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
)
),),
],),
Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Flexible(
flex: 1,
child:IconButton(
icon: new Icon(Icons.arrow_back_ios),
color: Colors.white,
onPressed: (){},
)
),
],),
],
),)
);
}
The above code also tried without stack by Using Row with expanded but the text alignment going wrong the text getting center to its expanded widget n
return Scaffold(
body: Stack(
children: <Widget>[
Container(
decoration: _buildBackground(),
),
Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 13,
child:_toolBar('VENUE LOGIN')
),
Expanded(
flex: 87,
child: Container(
child: LoginBody(),
),
)
],
)
],
),
);

You can try center your Text and IconButton widgets.
Stack(
children: <Widget>[
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 1,
child: Text(headerText,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
)),
),
],
),
),
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Flexible(
flex: 1,
child: IconButton(
icon: new Icon(Icons.arrow_back_ios),
color: Colors.white,
onPressed: () {},
)),
],
),
),
],
),

You can Try like this
appBar: PreferredSize(
preferredSize: Size(null, 100),
child: Container(
width: MediaQuery.of(context).size.width,
height: 100,
child: ClipRRect(
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(15),
bottomRight: Radius.circular(15)
),
child: Container(
color: Colors.green,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Icon(Icons.navigate_before,size: 40,),
Text("Center",style: TextStyle(fontSize: 30),),
Icon(Icons.navigate_before,color: Colors.transparent,),
],
),
),
),
),
),

Flutter | How to make custom button of BottomNavigationBar in flutter?

I want make a button with text and icon inside it, with custom background color and custom width. with fix position (not scrollable). would you like to help me please ?
here are the code:
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.shifting,
currentIndex: 0, // this will be set when a new tab is tapped
items: [
BottomNavigationBarItem(icon: Icon(Icons.supervised_user_circle), title: Text('Players'),backgroundColor: Colors.red),
BottomNavigationBarItem(icon: Icon(Icons.whatshot), title: Text('Trending'),backgroundColor: Colors.blueAccent),
BottomNavigationBarItem(icon: Icon(Icons.access_time), title: Text('Highlights'),backgroundColor: Colors.yellow)
]
its only give a color for the icon.
this is what I want:

Here you go
Widget build(context) {
return Scaffold(
bottomNavigationBar: Container(
height: 56,
margin: EdgeInsets.symmetric(vertical: 24, horizontal: 12),
child: Row(
children: <Widget>[
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.chat, color: Colors.white), Text("CHAT", style: TextStyle(color: Colors.white))],
),
),
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.notifications_active, color: Colors.white), Text("NOTIF", style: TextStyle(color: Colors.white))],
),
),
Expanded(
child: Container(
alignment: Alignment.center,
color: Colors.red,
child: Text("BUY NOW", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 18)),
),
),
],
),
),
);
}

You may want to look at the concept of a BottomAppBar instead.
This bar accepts any widget as children not just BottomNavigationBarItems.
You could try this:
BottomAppBar(
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Expanded(
child: SizedBox(
height: 44,
child: Material(
type: MaterialType.transparency,
child: InkWell(
onTap: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.add, color: Colors.blue, size: 24),
Text("Add")
],
),
),
),
),
),
]
),
)
