I got following code:
FlatButton.icon(
minWidth: double.infinity,
padding: EdgeInsets.symmetric(
vertical: kDefaultPadding,
),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10),
),
color: kPrimaryColor,
onPressed: () {},
icon: WebsafeSvg.asset("assets/Icons/Edit.svg", width: 16),
label: Text(
"New message",
style: TextStyle(color: Colors.white),
),
).addNeumorphism(
topShadowColor: Colors.white,
bottomShadowColor: Color(0xFF234395).withOpacity(0.2),
),
It seems the FlatButtun is now deprecated and I must convert it to TextButton but when I try that, it gives me errors for minWith parameter. When I try to wrap it with ConstrainedBox I get other errors for padding shape, etc.
I don't know how make this old code work as expected before?
As I've commented, you can't just "convert" a FlatButton.icon to a TextButton.icon. The changes in the buttons are breaking changes made to Flutter:
A new set of basic material button widgets and themes have been added
to Flutter. The original classes have been deprecated and will
eventually be removed. The overall goal is to make buttons more
flexible, and easier to configure via constructor parameters or
themes.
So, to solve your problem, you'll have to compose your own widgets to get close to FlatButton.icon.
For your example, you can use the Padding widget for padding, and SizedBox for the width. for rounded corners, you can use the style property.
Your button code can look something like this using TextButton.icon:
SizedBox(
width: double.infinity,
child: Padding(
padding: EdgeInsets.symmetric(
vertical: 10,
),
child: TextButton.icon(
//rounded corners
style: ButtonStyle(
shape: MaterialStateProperty.all<RoundedRectangleBorder>(
RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
),
),
),
onPressed: () {},
icon: WebsafeSvg.asset("assets/Icons/Edit.svg", width: 16),
label: Text(
"New message",
style: TextStyle(color: Colors.white),
),
),
),
)
How to fix this parameter name error. It error after I change OutlinedButton. Someone can help me.
Padding(
padding: EdgeInsets.fromLTRB(0, 10, 10, 10),
// ignore: deprecated_member_use
child: OutlinedButton(
padding: EdgeInsets.fromLTRB(30, 0, 30, 0),
textColor: secondaryColor,
borderSide: BorderSide(color: secondaryColor),
child: Text('Send Notification'),
onPressed: () => _sendNotificationDialog(context),
shape: new RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(30.0),
),
),
),
FlatButton, Raised button and some widgets are now deprecated from the flutter framework. They wanted to distinguish the styling of the button from the rest of the widget. As you can see hear: New buttons and button themes
Outlined button is not deprecated. To give style to it, you need to override the parameter 'style', like the code below:
OutlinedButton(
style: OutlinedButton.styleFrom(
padding: EdgeInsets.fromLTRB(30, 0, 30, 0),
shape: RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(30.0),
side: BorderSide(
color: secondaryColor,
),
),
),
child: Text('Send Notification'),
onPressed: () => _sendNotificationDialog(context),
),
What did you had before OutlinedButton ?
The code error means that the parameters you try to assign, doesn't exist in the OutlineButton Widget
Edit :
What I've found is that the buttons were migrated. it could be useful for other of your buttons :
See the migration guide in flutter.dev/go/material-button-migration-guide). ' 'This feature was deprecated after v1.26.0-18.0.pre.'
You can try to use style argument instead. You'll find plenty of parameters to edit your button
OutlinedButton(
style: ButtonStyle(
shape: ,
textStyle: ,
), onPressed: () { },
child: const Text('Hello'),
)
I have an elevated button in Flutter, generally the button works fine.
However, the setting of the primary: Colors.red in this example does not work, the button is transparent for some reason... All the other params of the ElevatedButton.styleFrom() are working as expected.
Any assistance would be appreciated!
Widget _btnGood() {
return SizedBox(
width: MediaQuery.of(context).size.width * 0.8,
child: ElevatedButton(
onPressed: null,
style: ElevatedButton.styleFrom(
primary: Colors.purple,
side: const BorderSide(width: 8.0, color: Colors.white),
shape:
RoundedRectangleBorder(borderRadius: BorderRadius.circular(32)),
padding: const EdgeInsets.all(25),
),
child: const Text(
"Im Feeling Good",
style: TextStyle(
color: Colors.white,
fontSize: 30,
),
),
),
);
}
Example of Button
Simply change on pressed to-
on_pressed: (){} instead of null.
I was using the RaisedButton untill the Flutter deprecated it and we couldn't use it anymore. There was a suggestion saying "Use ElevatedButton instead". So I tried using it but I couldn't see the properties like color, elevation, focusColor etc.
So how can I personalize an ElevatedButton?
To change the properties of ElevatedButton you should be using the style: property like so:
ElevatedButton(
style: ElevatedButton.styleFrom(
primary: Colors.blue, //button's fill color
onPrimary: Colors.red, //specify the color of the button's text and icons as well as the overlay colors used to indicate the hover, focus, and pressed states
onSurface: Colors.orange, //specify the button's disabled text, icon, and fill color
shadowColor: Colors.black, //specify the button's elevation color
elevation: 4.0, //buttons Material shadow
textStyle: TextStyle(fontFamily: 'roboto'), //specify the button's text TextStyle
padding: const EdgeInsets.only(top: 4.0, bottom: 4.0, right: 8.0, left: 8.0), //specify the button's Padding
minimumSize: Size(20, 40), //specify the button's first: width and second: height
side: BorderSide(color: Colors.yellow, width: 2.0, style: BorderStyle.solid), //set border for the button
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(35.0)), // set the buttons shape. Make its birders rounded etc
enabledMouseCursor: MouseCursor.defer, //used to construct ButtonStyle.mouseCursor
disabledMouseCursor: MouseCursor.uncontrolled, //used to construct ButtonStyle.mouseCursor
visualDensity: VisualDensity(horizontal: 0.0, vertical: 0.0), //set the button's visual density
tapTargetSize: MaterialTapTargetSize.padded, // set the MaterialTapTarget size. can set to: values, padded and shrinkWrap properties
animationDuration: Duration(milliseconds: 100), //the buttons animations duration
enableFeedback: true, //to set the feedback to true or false
alignment: Alignment.bottomCenter, //set the button's child Alignment
),
onPressed: () => {} , //set both onPressed and onLongPressed to null to see the disabled properties
onLongPress: () => {}, //set both onPressed and onLongPressed to null to see the disabled properties
child: Text('ElevatedButton')
),
Change individual button color. Use style property.
ElevatedButton(
onPressed: () {},
child: Text('Button'),
style: ElevatedButton.styleFrom(
backgroundColor: Colors.red,
),
)
Change all buttons color down the widget tree. Use ElevatedButtonTheme:
ElevatedButtonTheme(
data: ElevatedButtonThemeData(
style: ElevatedButton.styleFrom(
backgroundColor: Colors.red, // Sets color for all the descendant ElevatedButtons
),
),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(
onPressed: () {},
child: Text('Button 1'),
),
SizedBox(height: 12),
ElevatedButton(
onPressed: () {},
child: Text('Button 2'),
),
],
),
)
You can use ElevatedButton.styleFrom to change shadow and color.
ElevatedButton(
style: ElevatedButton.styleFrom(
primary: Colors.blue,
shadowColor: Colors.black))
I want to apply background color for icon button but I don't see an explicit backgroundColor property for it. I want to achieve this:
Currently I was able to achieve till here:
Below is the code so far:
#override
Widget build(BuildContext context) {
return Scaffold(
resizeToAvoidBottomPadding: false,
backgroundColor: Color(0xFF13212C),
appBar: AppBar(
title: Text('Demo'),
),
drawer: appDrawer(),
body: new Center(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
// mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
new Column(
children: <Widget>[
// new Flexible(
new TextField(
style: new TextStyle(
color: Colors.white,
fontSize: 16.0),
cursorColor: Colors.green,
decoration: new InputDecoration(
suffixIcon: new IconButton(
icon: new Image.asset('assets/search_icon_ivory.png'),onPressed: null),
fillColor: Colors.black,
contentPadding: new EdgeInsets.fromLTRB(10.0, 20.0, 10.0, 20.0),
filled: true,
hintText: 'What Do You Need Help With?',
hintStyle: new TextStyle(
color: Colors.white
)
)
)
// )
]
),
You can use a Circular Avatar with the radius = text field's height/2 or whatever height you prefer.
To figure out text field specs you can visit material.io
So the chunk of code is going to be like the following:
CircleAvatar(
radius: 30,
backgroundColor: Color(0xff94d500),
child: IconButton(
icon: Icon(
Icons.search,
color: Colors.black,
),
onPressed: () {
...
},
),
),
This way you get an Icon button with background color.
I hope this can help you guys.
you can wrap your IconButton with Container and use color property to achieve desire output.
May Following Example help You.
suffixIcon: Container(
color: Colors.green,
child: new IconButton(
icon: new Icon(Icons.search,color: Colors.white,),onPressed: null),
),
You can achieve it with TextButton
TextButton(
style: TextButton.styleFrom(
backgroundColor: colorScheme.primary,
shape: CircleBorder(),
),
child: Icon(
MdiIcons.send,
color: colorScheme.onPrimary,
),
onPressed: () {},
),
The output will look like this:
From the official Flutter docs:
Adding a filled background
Icon buttons don't support specifying a
background color or other background decoration because typically the
icon is just displayed on top of the parent widget's background. Icon
buttons that appear in AppBar.actions are an example of this.
It's easy enough to create an icon button with a filled background
using the Ink widget. The Ink widget renders a decoration on the
underlying Material along with the splash and highlight InkResponse
contributed by descendant widgets.
Tl;dr: IconButton doesn't support background color out-of-the-box. Use this workaround to add the background color and the splash effect when clicking the button:
Ink(
decoration: ShapeDecoration(
color: Colors.blue,
shape: CircleBorder(),
),
child: IconButton(
icon: Icon(Icons.add),
color: Colors.white,
onPressed: () {},
),
),
Live Demo
This is now the officially recommended way to set background color on an IconButton, and the flutter docs have been updated to reflect this.
Hope, this will satisfied you
Ink(
decoration: ShapeDecoration(
color: Colors.red,
shape: CircleBorder(),
),
child: IconButton(
icon: Icon(Icons.delivery_dining),
onPressed: () {
print('pressed');
},
),
),
You can not do that with IconButton widget yet. Good news is that you may replace it with FlatButton like that:
suffixIcon: new FlatButton(
color: Colors.green,
disabledColor: Colors.green[100],
child: Icon(Icons.search)),
color will be used in case onPressed handler is defined, otherwise it will be rendered with disabledColor background.
IconButton does not support that, and RaisedButton recently is deprecated in favour of ElevatedButton, which supports changing background colours as well as shapes, but you cannot easily make it a perfect circle.
So to think out of the box, why not use a FloatingActionButton? They are just widgets too, so they can appear anywhere on the screen. For example, I'm using a FAB in a video chat demo app to toggle cameras.
Example code:
FloatingActionButton(
child: Icon(
Icons.flip_camera_ios_outlined,
color: Colors.white,
),
onPressed: () {
// do your thing here
},
)
And if you aren't happy about its default size, you can always wrap it with a SizedBox to change the width however you see fit.
With latest flutter and material-3 design system, this is just a piece a cake.
IconButton(
onPressed: () { ... },
icon: const Icon(Icons.search),
style: IconButton.styleFrom(backgroundColor: Colors.redAccent),
),
Add a Material
Material(
color:Colors.green
child:IconButton(
icon: Icon(Icons.add),
color: Colors.white,
onPressed: () {},
));
Official solution:
Depends on official documentation of flutter about IconButton Class:
Adding a filled background
Icon buttons don't support specifying a background color or other
background decoration because typically the icon is just displayed on
top of the parent widget's background. Icon buttons that appear in
[AppBar.actions] are an example of this.
It's easy enough to create an icon button with a filled background
using the [Ink] widget. The [Ink] widget renders a decoration on the
underlying [Material] along with the splash and highlight
[InkResponse] contributed by descendant widgets.
So the code will be like this:
Material(
color: Colors.transparent,
child: Ink(
decoration: ShapeDecoration(
color: Colors.white,
shape: CircleBorder(),
),
child: IconButton(
tooltip: "Some Text...",
icon: Icon(Icons.flash_off),
color: Colors.black,
onPressed: () {},
),
),
);
See official example code from flutter, click here ...
Note: Reason to wrap it with Material widget because Ink is drawn
on the underlying Material widget, if you remove it decoration will not appear.
I've used multiple colors to demonstrate You can do as you want. And I say that You put your IconButton into Material widget. This will also solve your Splash Color (which is slightly grey color with some transparency).
If you want it raised, you can use RaisedButton like this:
ConstrainedBox(
constraints: BoxConstraints(maxWidth: 50),
child: RaisedButton(
color: kColorLightGrey,
padding: EdgeInsets.symmetric(
vertical: 12,
),
shape: StadiumBorder(),
child: Icon(Icons.refresh),
onPressed: () {
},
),
),
SizedBox(
height: 38,
width: 38,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
primary: Colors.grey,
onPrimary: Colors.red,
padding: EdgeInsets.zero,
shape: const CircleBorder(),
),
onPressed: () {},
child: const Icon(Icons.refresh),
);
You can use FloatingActionButton for such case But you cannot use FAB in a widget for multi use, it shows error. In such case use this code. It will work on images also.
Card(
color: Colors.blue,
shape: CircleBorder(),
child: IconButton(
icon: const Icon(
Icons.edit,
size: 20,
color: Colors.white,
),
onPressed: () {
print('tapped');
},
));
You can solve this with a GestureDetector and a container. I like using this solution because of the variety of controls it gives you from the combination.
Additionally, GestureDetector opens up more interaction events if you want to incorporate those across devices.
GestureDetector(
onTap: () {},
child: ClipOval(
child: Container(
//add extra margin to visual center icon if icon isn't balanced
color: backgroundColor,
width: size,
height: size,
child: Icon(
Icons.question_mark_sharp,
size: size * 0.6, //size to your preference
color: iconColor,
),
),
),
);
Alternatively you can do this from another question circle icon button
RawMaterialButton(
onPressed: () {},
elevation: 2.0,
fillColor: Colors.white,
child: Icon(
Icons.pause,
size: 35.0,
),
padding: EdgeInsets.all(15.0),
shape: CircleBorder(),
)
ElevatedButton with Theme.
ElevatedButton(
style: ButtonThemes.iconButton,
child: Icon(
icon,
color: color,
),
onPressed: () {},
)
static ButtonStyle get iconButton=> ButtonStyle(
backgroundColor: MaterialStateProperty.all(
backgroundColor,
),
...
);
