I want to remove some extra space between two IconButton in Row widget
I tried much more but still not able to remove space between widgets
Column(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text("Home",
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 15,
color: Colors.black
)
),
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
IconButton(
icon: Icon(
Icons.edit,
color: Colors.black,
size: 20,
),
onPressed: () {
IntelUtility.navigateToScreen(
context, EditHomeAddressScreen()
);
},
),
IconButton(
icon: Icon(
Icons.delete,
color: Colors.black,
size: 20,
),
onPressed: () {},
),
],
),
],
),
],
),
Please help to solving this issue i am in trouble :(
Instead of using IconButton,
you can use CupertinoButton like this :
CupertinoButton(
minSize: double.minPositive,
padding: EdgeInsets.zero,
child: Icon(
Icons.delete,
color: Color.black,
size: 20
),
onPressed: () {},
)
Add param padding: EdgeInsets.all(0) to IconButton.
IconButton(
padding: EdgeInsets.all(0),
icon: Icon(
Icons.delete,
color: Colors.black,
size: 20,
),
onPressed: () {},
)
Your answer is BoxConstraints
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
IconButton(
constraints: BoxConstraints.tight(Size.fromWidth(30)),
icon: Icon(
Icons.edit,
color: Colors.black,
size: 20,
),
onPressed: () {
IntelUtility.navigateToScreen(
context, EditHomeAddressScreen()
);
},
),
IconButton(
constraints: BoxConstraints.tight(Size.fromWidth(30)),
icon: Icon(
Icons.delete,
color: Colors.black,
size: 20,
),
onPressed: () {},
),
],
),
You can change constraints: BoxConstraints.tight(Size.fromWidth(30)), whatever you want

This is the expected screen and the container will collapse and expand based on the text displayed and should only occupy the space left out by placing other icons.
But see the flutter implemented screen.
The icons are moved to the right on container expansion and shows overflowed pixel error.
My code
Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
IconButton(
icon: const Icon(
Icons.menu,

size: 34,
),
onPressed: () {},
),

style: TextStyle(

fontWeight: FontWeight.bold),

Icon(
Icons.arrow_drop_down,
color: Colors.black,
),
]),
),
),
),
onTap: () {
//todo show bottom sheet dialog here.
},
),
const Spacer(), // I just added one line
IconButton(
icon: Image.asset('assets/images/ic_scan.png'),
iconSize: 20,
onPressed: () {},

IconButton(

Remove the spacer and add the dropdown in a flexible widget
Padding(
padding: const EdgeInsets.symmetric(horizontal: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,

IconButton(

I want to create a second row after the icon "Bearbeiten", but this is not possible, because I need to use "title" for the first row. child: ResponsiveDatatable(title: Row(
I want to have a code like this below. How can I use ResponsiveDatatable, but although use a second row for my buttons?
This image shows, how the code looks at the moment
(without the second row). Because there is not enough space in one row, I want to create a second row.
How can I do this with a ResponsiveDatatable?

What you are expecting is the functionality of the Column.
ResponsiveDatatable(
title: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
children: [
TextButton.icon(
onPressed: () => {
Navigator.of(context)

icon: Icon(
Icons.add,
color: Colors.black,
),
label: Text("Hinzufügen",
style: TextStyle(
color: Colors.black,
)),
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all<Color>(
Colors.grey),
padding: MaterialStateProperty.all<EdgeInsets>(
EdgeInsets.all(10)),
),
),
SizedBox(width: 30,),
TextButton.icon(
onPressed: () => {
Navigator.of(context)
.pushNamed(RegristrationRoute)
//Pop-up Fenster für die Registration machen, wenn Zeit - ansonsten registrationsfenster weiterleiten
},
icon: Icon(

And there is a minor error in the parenthesis closing also.
Note: It will solve your problem but still it will not meet responsiveness.
I had the similar problem.
Instead of TextButton, I made a button-UI in container and wrapped it with InkWell (A rectangular area of a Material that responds to touch).
InkWell(
// on Tap function used and call back function as defined here
onTap: () {
setState(() {
// state will be set when the inkwell area is tapped
inkwell='Inkwell Tapped';
});
},
onLongPress: () {
setState(() {
inkwell='InkWell Long Pressed';
});
},
child: Container(
// container displaying the text
color: Colors.green,
width: 120,
height: 70,
child: Center(
child: Text(
'Button text',
))),
),
When the keyboard is activated, persistentFooterButtons are covered.
...
persistentFooterButtons: <Widget>[
ButtonBar(
children: [
IconButton(
iconSize: 15,
onPressed: () {},
icon: Icon(Icons.east, color: Colors.green),
),
IconButton(
iconSize: 15,
onPressed: () {},
icon: Icon(Icons.api, color: Colors.blue),
),],),],
); //Scaffold
When the keyboard is activated, the icons should be displayed above the keyboard.
write in floatingActionButton
for example :
floatingActionButton: Column(
children: [
Row(
children: [
Expanded(child: Container()),
FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: Icon(Icons.add),
),
],
),
Container(
height: 1, color: Colors.grey , margin: EdgeInsets.only(top: 10 , left: 30),
),
Container(
child: ButtonBar(
children: [
IconButton(
iconSize: 15,
onPressed: () {},
icon: Icon(Icons.extension, color: Colors.green),
),
IconButton(
iconSize: 15,
onPressed: () {},
icon: Icon(Icons.ac_unit, color: Colors.blue),
),
],
),
)

need to position the Flatbutton in the right bottom. need to position the Iconbuttons in middle and space between the middle and bottom.
I have a IconButton and want to stack two icons to look like
I tried with Row layout like
CircleAvatar(
radius: avatarRadius,
child: IconButton(
icon: Row(
children: [
Icon(
Icons.add,
color: Colors.white,
),
Icon(
Icons.message,
color: Colors.white,
),
]
),
onPressed: _onAddMessageButtonClick,
),
),
But it is giving error
A RenderFlex overflowed by 24 pixels on the right.
Remove IconButton widgets
Try this
CircleAvatar(
radius: 40,
child: GestureDetector(
onTap: (){
// perform click here
},
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Icon(
Icons.add,
color: Colors.white,
),
Icon(
Icons.message,
color: Colors.white,
),
]
),
),
),
