I am using a package fab_circular_menu, That package is for an animated floating action button which opens up a circular menu. within it I want a widget as a menu item such that there is an icon and a text below. the icon is centered with text.
e.g.
How can I achieve this, as of now I am using the code below but it does not work well with different screen size.
FlatButton(
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(100),
),
padding: EdgeInsets.only(bottom: 15),
onPressed: () async {
await _auth.signOut().then((value) {
Navigator.of(context).popUntil((route) => route.isFirst);
});
},
child: Stack(
overflow: Overflow.visible,
children: <Widget>[
Icon(Icons.power_settings_new),
Positioned(
bottom: -12,
right: -10,
child: Text('Logout'),
),
],
),
),
Another Solution which could use in many ways
Wrap(
direction: Axis.vertical,
crossAxisAlignment: WrapCrossAlignment.center,
children: <Widget>[
Icon(Icons.power_settings_new),
Text('Logout'),
],
),
You can achieve this result with Column widget instead of Stack.
Here is the example:
.....
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Icon(Icons.power_settings_new),
Text('Logout'),
],
),
Short answer:
Column(
mainAxisSize: MainAxisSize.min,
children: [
Icon(Icons.call),
SizedBox(height: 4), // spacing between two
Text('Call Icon'),
],
)
Long answer:
Copy this class:
class TextWithIcon extends StatelessWidget {
final IconData icon;
final String text;
final double spacing;
const TextWithIcon({Key key, this.icon, this.text, this.spacing = 2}) : super(key: key);
#override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.all(8),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
Icon(icon),
SizedBox(height: spacing),
Text(text),
],
),
);
}
}
Usage:
TextWithIcon(
icon: Icons.call,
spacing: 6, // Space between icon and text
text: 'Call Icon',
)
You can use columns for this like:
FlatButton(
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(100),
),
padding: EdgeInsets.only(bottom: 15),
onPressed: () async {
await _auth.signOut().then((value) {
Navigator.of(context).popUntil((route) => route.isFirst);
});
},
child: Column(
children: <Widget>[
Icon(Icons.power_settings_new),
SizedBox(height:10), // set height according to your needs
Text('Logout'),
],
),
),
So I'm trying to remove the bottom margin of raisedButton so it will look like it is merged with the card below it.
here's what it looks like
here is my code
Expanded(
child: Card(
elevation: 5,
// shape:
// RoundedRectangleBorder(borderRadius: BorderRadius.circular(22)),
child: Column(
children: <Widget>[
Row(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Apakah anak sudah bisa ... ?",
style: TextStyle(fontWeight: FontWeight.bold)),
),
],
),
Row(
children: <Widget>[
Expanded(
child: RaisedButton(
child: Text(
"Iya",
style: TextStyle(color: Colors.white),
),
color: Colors.green[300],
onPressed: () {}),
),
Expanded(
child: RaisedButton(
child: Text(
"Tidak",
style: TextStyle(color: Colors.white),
),
color: Colors.red[200],
onPressed: () {}))
],
)
],
),
),
)
or do you guys have any other alternative solution to achieve that?
You can explicitly set your Row height to match the height of your RaisedButton. Simply wrap it inside a Container and add the height attribute.
If you want to, you can access the default height by using Theme.of(context).buttonTheme.height. Theme.of returns the ThemeData used in the current context.
Here a minimal example:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: Container(
child: Card(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('Test'),
Container(
height: Theme.of(context).buttonTheme.height,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
RaisedButton(
onPressed: () {},
child: Text('Yes'),
color: Colors.green,
),
RaisedButton(
onPressed: (){},
child: Text('No'),
color: Colors.red,
)
],
),
),
],
)
),
),
)),
);
}
}
I had the same problem. NikasPor's answer didnt work for me, unfortunately. The way I fixed it is by seeting the crossAxisAlignment on the row to .stretch
Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children:[ /* Buttons Here */]
)
I am trying to match this design
on tap the card should expand
I cannot use a card wrapping an expansion tile because the expansion tile is basically only one row, I was trying to follow this example
flutter_catalog
I googled a lot and could not find an example of what I am trying to achieve, the closest thing I could find on stackoverflow was this other question is there not in flutter a collapsible / expansible card?
You can absolutely use a Card wrapping an ExpansionTile. The ExpansionTile has a title property which takes a Widget so you can pass any Widget you want into it.
Messy example code, but hopefully you get the idea:
class ExpandedTile extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(15.0))),
elevation: 2,
margin: EdgeInsets.all(12.0),
child: Padding(
padding: const EdgeInsets.all(8.0),
child: ExpansionTile(
backgroundColor: Colors.white,
title: _buildTitle(),
trailing: SizedBox(),
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
children: <Widget>[
Text("Herzlich Willkommen"),
Spacer(),
Icon(Icons.check),
],
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
children: <Widget>[
Text("Das Kursmenu"),
Spacer(),
Icon(Icons.check),
],
),
)
],
),
),
);
}
Widget _buildTitle() {
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
children: <Widget>[
Text("MODUL 1"),
Spacer(),
Text("Mehr"),
],
),
Text("Kursubersicht"),
Row(
children: <Widget>[
Text("6 Aufgaben"),
Spacer(),
FlatButton.icon(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(15.0))),
padding: EdgeInsets.symmetric(vertical: 4.0, horizontal: 8.0),
color: Colors.blue,
textColor: Colors.white,
onPressed: () {},
icon: Icon(Icons.play_arrow),
label: Text("Fortsetzen"),
),
],
),
],
);
}
}
produces
and when tapped
I want to create a persistentFooterButtons with 3 FlatButton.icon
to equally take the whole width of the Screen, and customize itself with different screen sizes, i tried many approaches like Wrap,Expanded, i couldn't make it work, i even tried
final screenSize = MediaQuery.of(context).size;
Container(
width: screenSize.width /3 ,
child: FlatButton.icon(
onPressed: null,
icon: Icon(Icons.search),
label: Text("search")),
),
but the text always overflows on the right side of the screen.
So, Any ideas how this might go?
**Edit**
i found this approach which is very helpful
persistentFooterButtons: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
FlatButton(
onPressed: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
new Icon(Icons.lightbulb_outline),
new Text('Idea'),
],
),
),
FlatButton(
onPressed: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
new Icon(Icons.lightbulb_outline),
new Text('Idea'),
],
),
),
FlatButton(
onPressed: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
new Icon(Icons.lightbulb_outline),
new Text('Idea'),
],
),
),
],
),
],
The only problem is that mainAxisAlignment property doesn't make any changes, so the three buttons are sided together
See here
Any help?
For create a persistentFooterButtons you need to use bottomNavigationBar.
And For create 3 flatButton with equal size, you need to use flex attribute inside Expanded Widget.
Scaffold(
body: Container(
color: Colors.white,
child: Center(child: Text("Flutter"),),
),
bottomNavigationBar: new Container(
padding: EdgeInsets.all(0.0),
child: Row(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 1,
child: FlatButton.icon(
onPressed: () {
},
icon: Icon(Icons.search),
label: Text("Search"),
),
),
Expanded(
flex: 1,
child: FlatButton.icon(
onPressed: () {
},
icon: Icon(Icons.search),
label: Text("Search"),
),
),
Expanded(
flex: 1,
child: FlatButton.icon(
onPressed: () {
},
icon: Icon(Icons.search),
label: Text("Search"),
),
),
],
),
),
);
Can someone explain to me how can i center the FloatingActionButton inside the persistentFooterButtons. im missing something here.
List _footer() {
return <Widget>[
new ButtonBar(
children: <Widget>[
new Container(
child: new Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new FloatingActionButton(
backgroundColor: Colors.redAccent,
onPressed: () => {},
),
],
),
)
],
)
];}
===
#override Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text("Question"),
),
body: _body(),
persistentFooterButtons: _footer(),
); }
I looked at the code of Scaffold, below is how persistentFooterButtons created:
new Container(
decoration: new BoxDecoration(
border: new Border(
top: Divider.createBorderSide(context, width: 1.0),
),
),
child: new SafeArea(
child: new ButtonTheme.bar(
child: new SafeArea(
top: false,
child: new ButtonBar(
children: widget.persistentFooterButtons
),
),
),
),
)
You can see here, your buttons are wrapped by a ButtonBar. Now let's look at the ButtonBar code below, the DEFAULT alignment is MainAxisAlignment.end. I guess this follows the Material guidelines.
const ButtonBar({
Key key,
this.alignment: MainAxisAlignment.end,
this.mainAxisSize: MainAxisSize.max,
this.children: const <Widget>[],
}) : super(key: key);
The Flutter framework is being updated, but till today (2018 June 08th), you can not put the buttons to the center using persistentFooterButtons.
Solution: I suggest you follow my answer here to put your buttons at the center-bottom of the screen.
I found an easy solution is to wrap the FloatingActionButton in a sized box that is the same width as the screen.
persistentFooterButtons: <Widget>[
SizedBox(
width: MediaQuery.of(context).size.width,
child: FloatingActionButton(
onPressed: () {
print('Close pressed');
},
child: Text('Close'),
)
)
],
I have the same problem. I achieved the desired result with this:
persistentFooterButtons: [
Container(
width: MediaQuery.of(context).copyWith().size.width,
child: Row(
children: [
Expanded(
child: FlatButton(
child: Text('Your centered button'),
onPressed: (){},
),
)
],
),
)
]
I've used a flatbutton just as example but it works as well with floatinActionButtons.
Hope it helps
Found yet another solution. MaterialTheme (theme_data.dart) has buttonBarTheme attribute. You can modify it like following:
var myTheme = ThemeData(
buttonBarTheme: ButtonBarThemeData(
alignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
),
)
And specify it in your MaterialApp widget:
MaterialApp(theme: myTheme)
For anyone trying something similar, but instead of a FloatingActionButton, a set of, let's say two ElevatedButtons, you can center them like this:
...
persistentFooterButtons: [
Center(
child: Column(
children: [
ElevatedButton(), //Button 1
SizedBox(),
ElevatedButton(), //Button 2
],
),
),
],
...
In hope that anyone might find it useful in the future.
floatingActionButton can be aligned or positioned by making use of floatingActionButtonLocation property, however it is not useful for button placed inside persistentFooterButtons.
The persistentFooterButtons are wrapped inside ButtonBar and we don't have any way to override the ButtonBar default alignment of MainAxisAlignment.end for persistentFooterButtons.
Flutter team could have provided persistentFooterButtonsAlignment property but without it, one can achieve similar layout using following bottomNavigationBar hack, if it is not already being used for something else.
bottomNavigationBar: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Divider(
height: 0,
),
Padding(
padding: const EdgeInsets.all(8.0),
child: FlatButton(
child: Text('Button'),
color: Theme.of(context).primaryColor,
materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
padding: EdgeInsets.symmetric(horizontal: 16.0, vertical: 12.0),
textColor: Theme.of(context).colorScheme.background,
onPressed: () {},
),
),
],
),
