I'm trying to center the minimized icon in this Icon Button but can't get it to work:
#override
Widget build(BuildContext context) {
return Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
SizedBox(
height: 25,
child: TextButton(
onPressed: appWindow.minimize,
style: const ButtonStyle(
alignment: Alignment.center,
padding: MaterialStatePropertyAll(EdgeInsets.all(0))),
child: const Icon(
Icons.minimize,
color: Colors.white,
),
),
),
TextButton(
onPressed: maximizeOrRestore,
child: Icon(
appWindow.isMaximized ? Icons.fullscreen_exit : Icons.fullscreen,
color: Colors.white,
)),
TextButton(
onPressed: appWindow.close,
child: const Icon(
Icons.close,
color: Colors.white,
),
)
],
);
}
I'm expecting the button to be centered and as you can see i've already tried using alignment and padding
When you say "center the minimized icon", do you mean that this icon should be between the other two icons? In that case, you just need to switch the first two widgets in the Row widget's children.
But I think you want the minimize icon to be higher so that it's something like-> - ◾️ X
If this is what you want then you can't use Icons.minimize. If you check out this icon on this page, you will notice that the minimize icon looks like an underscore. This is by design. I think this looks good, but if you insist on having a minus sign kind of symbol then you can use Icons.remove_rounded.
It's not that the icon is not centered, the Material minimize icon has blank space in the upper size, because it is suppose to be down to understand that is a minimize button just like the maximize button has blank space in the bottom size. What you can try is to use a different icon if you really want it to be centered. Try with Icons.horizontal_rule.
You can use CupertinoIcons.minus like
TextButton(
onPressed: appWindow.minimize,
child: const Icon(
CupertinoIcons.minus,
color: Colors.white,
),
),
Is there a way to close the flutter speedDial when tap on a label widget?. I did not use SpeedDial's child property, but it has that feature. Currently when I tap on a label widget it stays until I manually close the widget. Or even a way to change the child property of SpeedDial widget would be enough, while I want a custom shape like in the picture.
Navigator.pop() did not work
SpeedDial(
buttonSize: const Size(45, 45),
animatedIcon: AnimatedIcons.menu_close,
children: [
SpeedDialChild(
labelWidget: GestureDetector(
onTap: () async {
Feedback.forTap(context);
await _crudStorage.deleteAllTask();
},
child: Container(
height: 50.0,
decoration: BoxDecoration(
color:
Theme.of(context).cardColor,
border: Border.all(width: 2.0),
borderRadius:
BorderRadius.circular(30.0),
),
child: Row(
children: [
const Padding(
padding: EdgeInsets.only(
left: 12.0, right: 8.0),
child:
Text('Clear all tasks'),
),
Padding(
padding:
const EdgeInsets.only(
right: 8.0),
child: SvgPicture.asset(
'assets/svg/all.svg',
),
),
],
),
),
),
),
],
)
don't use async & await on tap use separate function to Call
https://tutorialmeta.com/question/how-to-call-async-function-with-ontap-flutter
refer the above link
It was so simple. Also the development team, provided how to implement this on their official extension page on pub.dev go to pub. I will mention the same documentation for your reference:
first you need to create a value notifier:
ValueNotifier<bool> isDialOpen = ValueNotifier(false);
Then set openCloseDial to isDialOpen in your SpeedDial:
SpeedDial(
...
openCloseDial: isDialOpen,
...
)
Now you can change the state of dial open:
isDialOpen.value = false;
Example: Just set the value to false inside the onTap callback :)
onTap: () async {
Feedback.forTap(context);
await _crudStorage.deleteAllTask();
isDialOpen.value = false;
},
use closeManually: false in SpeedDial Contructor. The widget will close automatically on select any function.
I'm currently trying to add the text ('Filter'), underneath an icon inside of the actions field within an AppBar.
Without any text being added underneath it. the action aligned exactly with the text and hamburger menu icon
Example:
There are two issues I'm having:
When I add text, the filter icon moves up a little, I want the icon to be the same spot but text added understand.
I'm getting an overflow issue
How can I fix this?
Thanks!
_appbarActions = [
Column(
children: [
IconButton(icon: const Icon(Icons.filter_alt_outlined), onPressed: () {}),
Text('Filter'),
],
)
];
Try the below snippet code:
To remove the space between IconButton and Text use Icon only;
For the overflow error you can manage the icon size with text fontSize (styles);
For events wrap the column by InkWell widget
Container(
margin: const EdgeInsets.only(right: 8.0),
child: InkWell(
onTap: () {},
child: Stack(
children: [
Center(
child: Icon(Icons.filter_alt_outlined),
),
Positioned(
child: Text(
'Filter',
style: TextStyle(fontSize: 10.0),
),
bottom: 5,
),
],
),
),
)
I'm new to flutter and have been trying to get a list of chipsets wrapped in a Wrap widget with the ability to add more of them through a button shown in the image. However, the button isn't able to wrap along with the chipset horizontally. Below is an image of the design to make it clearer.
Code:
Container(
child: Wrap(
children: [
Container(
child: Wrap(
children: _chipsetList,
),
),
SizedBox(width: 2),
Container(
height: 35,
width: 35,
child: FittedBox(
child: FloatingActionButton(
heroTag: null,
elevation: 0,
shape: StadiumBorder(
side: BorderSide(width: 2.0)),
onPressed: () {
_getMoreChips(context);
},
child: Icon(Icons.add),
),
))
],
),),
I tried to experiment with SingleChildScrollView property or with Wrap direction but in vain. What could be a way to get this design working?
Seems you want to put chips and the button in the single wrap. To do so, combine them in a single list and use this list as wrap's children
List<Widget> items = List.from(_chipsetList); // copy
Widget button = FloatingActionButton();
items.add(button);
Wrap(
children: items,
)
Or, using spread operator
Wrap(
children: [
..._chipsetList,
FloatingActionButton(),
],
)
I want to have a row of IconButtons, all next to each other, but there seems to be pretty big padding between the actual icon, and the IconButton limits. I've already set the padding on the button to 0.
This is my component, pretty straightforward:
class ActionButtons extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
color: Colors.lightBlue,
margin: const EdgeInsets.all(0.0),
padding: const EdgeInsets.all(0.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
IconButton(
icon: new Icon(ScanrIcons.reg),
alignment: Alignment.center,
padding: new EdgeInsets.all(0.0),
onPressed: () {},
),
IconButton(
icon: new Icon(Icons.volume_up),
alignment: Alignment.center,
padding: new EdgeInsets.all(0.0),
onPressed: () {},
)
],
),
);
}
}
I want to get rid of most of the light blue space, have my icons start earlier on the left, and closer to each other, but I can't find the way to resize the IconButton itself.
I'm almost sure this space is taken by the button itself, 'cause if I change their alignments to centerRight and centerLeft they look like this:
Making the actual icons smaller doesn't help either, the button is still big:
thanks for the help
Simply pass an empty BoxConstrains to the constraints property and a padding of zero.
IconButton(
padding: EdgeInsets.zero,
constraints: BoxConstraints(),
)
You have to pass the empty constrains because, by default, the IconButton widget assumes a minimum size of 48px.
Two ways to workaround this issue.
Still Use IconButton
Wrap the IconButton inside a Container which has a width.
For example:
Container(
padding: const EdgeInsets.all(0.0),
width: 30.0, // you can adjust the width as you need
child: IconButton(
),
),
Use GestureDetector instead of IconButton
You can also use GestureDetector instead of IconButton, recommended by Shyju Madathil.
GestureDetector( onTap: () {}, child: Icon(Icons.volume_up) )
It's not so much that there's a padding there. IconButton is a Material Design widget which follows the spec that tappable objects need to be at least 48px on each side. You can click into the IconButton implementation from any IDEs.
You can also semi-trivially take the icon_button.dart source-code and make your own IconButton that doesn't follow the Material Design specs since the whole file is just composing other widgets and is just 200 lines that are mostly comments.
Wrapping the IconButton in a container simply wont work, instead use ClipRRect and add a material Widget with an Inkwell, just make sure to give the ClipRRect widget enough border Radius 😉.
ClipRRect(
borderRadius: BorderRadius.circular(50),
child : Material(
child : InkWell(
child : Padding(
padding : const EdgeInsets.all(5),
child : Icon(
Icons.favorite_border,
),
),
onTap : () {},
),
),
)
Instead of removing a padding around an IconButton you could simply use an Icon and wrap it with a GestureDetector or InkWell as
GestureDetector(
ontap:(){}
child:Icon(...)
);
Incase you want the ripple/Ink splash effect as the IconButton provides on click wrap it with an InkWell
InkWell(
splashColor: Colors.red,
child:Icon(...)
ontap:(){}
)
though the Ink thrown on the Icon in second approach wont be so accurate as for the IconButton, you may need to do some custom implementation for that.
Here's a solution to get rid of any extra padding, using InkWell in place of IconButton:
Widget backButtonContainer = InkWell(
child: Container(
child: const Icon(
Icons.arrow_upward,
color: Colors.white,
size: 35.0,
),
),
onTap: () {
Navigator.of(_context).pop();
});
I was facing a similar issue trying to render an Icon at the location the user touches the screen. Unfortunately, the Icon class wraps your chosen icon in a SizedBox.
Reading a little of the Icon class source it turns out that each Icon can be treated as text:
Widget iconWidget = RichText(
overflow: TextOverflow.visible,
textDirection: textDirection,
text: TextSpan(
text: String.fromCharCode(icon.codePoint),
style: TextStyle(
inherit: false,
color: iconColor,
fontSize: iconSize,
fontFamily: icon.fontFamily,
package: icon.fontPackage,
),
),
);
So, for instance, if I want to render Icons.details to indicate where my user just pointed, without any margin, I can do something like this:
Widget _pointer = Text(
String.fromCharCode(Icons.details.codePoint),
style: TextStyle(
fontFamily: Icons.details.fontFamily,
package: Icons.details.fontPackage,
fontSize: 24.0,
color: Colors.black
),
);
Dart/Flutter source code is remarkably approachable, I highly recommend digging in a little!
A better solution is to use Transform.scale like this:
Transform.scale(
scale: 0.5, // set your value here
child: IconButton(icon: Icon(Icons.smartphone), onPressed: () {}),
)
You can use ListTile it gives you a default space between text and Icons that would fit your needs
ListTile(
leading: Icon(Icons.add), //Here Is The Icon You Want To Use
title: Text('GFG title',textScaleFactor: 1.5,), //Here Is The Text Also
trailing: Icon(Icons.done),
),
I like the following way:
InkWell(
borderRadius: BorderRadius.circular(50),
onTap: () {},
child: Container(
padding: const EdgeInsets.all(8),
child: const Icon(Icons.favorite, color: Colors.red),
),
),
enter image description here
To show splash effect (ripple), use InkResponse:
InkResponse(
Icon(Icons.volume_up),
onTap: ...,
)
If needed, change icons size or add padding:
InkResponse(
child: Padding(
padding: ...,
child: Icon(Icons.volume_up, size: ...),
),
onTap: ...,
)
