The icon on FloatingActionButton extended is on left, how can i put the icon on right? after the text
floatingActionButton: FloatingActionButton.extended(
onPressed: (){},
label: Text("Next",),
icon: Icon(Icons.arrow_forward,
),
),
floatingActionButtonLocation: FloatingActionButtonLocation.endFloat
There isn't any direct way to do that.
But as a workaround, you could just pass a Row widget (Which contains a Text and Icon widgets) to label parameter.
floatingActionButton: FloatingActionButton.extended(
onPressed: () {},
label: Row(
children: <Widget>[Text("Proceed"), Icon(Icons.arrow_forward)],
),
icon: Container(),
),
Hope it helps.
I don't think you can do that with FloatingActionButton, but instead you can configure a RaisedButton to look very similar.
Just use it same as you would do it with FloatingActionButton.
floatingActionButton: RaisedButton(
child: Container(
height: 50.0,
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
const SizedBox(width: 16.0),
Text('Next', style: TextStyle(color: Colors.white, fontSize: 25),),
const SizedBox(width: 8.0),
Icon(Icons.arrow_forward, size: 30.0, color: Colors.white,),
const SizedBox(width: 20.0),
]),
),
color: Colors.blue,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30.0),
),
onPressed: () {
print('Do somenthing');
},
)
Hope this help.

I put an Image in a Stack because I want to have a x-Button in the upper right corner.
But I don't know, how to set the image like this.
It actual looks like this:
This is the code:
list.add(Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
child: Stack(children: [
Flexible(
child:
Image.network("${globals.api}/download/$nextPicture")),
Align(
alignment: const Alignment(0.95, -0.95),
child: IconButton(
icon:
const Icon(Icons.cancel, color: Colors.white, size: 25),
onPressed: () {
deleteSelectedImageRemote(nextPicture);
},
),
)
]),
)
]));
Do you have any suggestions, how to make it look like the Details page?
Thank you very much!
try this
list.add(Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
child: Stack(children: [
Container(
width:200,

I want to know how to swipe down on a page to start the pop animation, but I want the animation to play as we're swiping down. For exemple, the "swipe from left to right" on iOS to pop a page is amazing, because the page that will pop follows the finger swiping LTR. And I want to do the same but vertically, and we would be able to close it from anywhere in the scaffold (not necessarily from the top edge). My animation has an hero animation so it might be harder.
Here's how it looks now :
And I want to have this animation playing, but swiping down, not swiping from the left. (Like exactly this animation, or one where the page goes down).
Here is the page I want to swipe to close :

TreeDescription(this.tree, {this.goBackArrow = true});

I am having some troubles to position 2 buttons in a card in Flutter.
I had this:
But I want this:
My code for the buttons of this card is:
new ButtonTheme.bar(
child: new ButtonBar(
alignment: MainAxisAlignment.start,
children: <Widget>[
Row(
children: <Widget>[
Column(
children: <Widget>[
new FlatButton(
child: Icon(
Icons.share,
color: Colors.white,
),
color: Color.fromRGBO(68, 153, 213, 1.0),
shape: CircleBorder(),
onPressed: () {
Share.share(
data[index]["link"],
);
},
),
],
),
Column(
children: <Widget>[
FlatButton(
color:
Color.fromRGBO(161, 108, 164, 1.0),
child: const Text('Read Article'),
shape: new RoundedRectangleBorder(
borderRadius:
new BorderRadius.circular(
30.0)),
textColor: Colors.white,
onPressed: () {
launch(data[index]["link"],
forceWebView: false);
},
),
],
)
],
),
],
),
From the documentation
ButtonBar.children : The buttons to arrange horizontally
I think you are doing a lot of unnecessary stuff, to get the result just put the buttons inside ButtonBar without extra layout widgets like Row and Column
here is the code :
ButtonTheme.bar(
child: new ButtonBar(
alignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
FlatButton(
child: Icon(
Icons.share,
color: Colors.white,
),
color: Color.fromRGBO(68, 153, 213, 1.0),
shape: CircleBorder(),
onPressed: () {},
),
FlatButton(
color: Color.fromRGBO(161, 108, 164, 1.0),
child: const Text('Read Article'),
shape: new RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(30.0)),
textColor: Colors.white,
onPressed: () {},
),
],
),
),
You can use a different alignment on your ButtonBar or Row:
alignment: MainAxisAlignment.spaceBetween
I use this method to show a AlertDialog:
_onSubmit(message) {
if (message.isNotEmpty) {
showDialog(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return AlertDialog(
title: Center(child: Text('Alert')),
content: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children : <Widget>[
Expanded(
child: Text(
message,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.red,
),
),
)
],
),
actions: <Widget>[
FlatButton(
child: Text('Cancel'),
onPressed: () {
Navigator.of(context).pop();
}),
FlatButton(
child: Text('Ok'),
onPressed: () {
_inputTextController.clear();
Navigator.of(context).pop();
})
],
);
},
);
}
}
Everything is working but the buttons are aligned in right as shown on picture below:
I want to style some how the buttons, for example one on start other on end.
I searched in docs but only found how to make them "Stacked full-width buttons".
Any ideas how to style the buttons?
Update 2022/10/22
Flutter 2.5 introduced the actionsAlignment property:
AlertDialog(
title: ..
actions: ..
actionsAlignment: MainAxisAlignment.end
),
Customize widget
Edit the the widget itself: Under the AlertDialog there is a ButtonBar widget where you can use alignment: MainAxisAlignment.spaceBetween to align the buttons correctly. See this answer for an example of a custom AlertDialog widget.
Own button row
You could also remove the buttons under actions and add an own custom Row with RaisedButtons in it, somehow like this:
Row (
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
RaisedButton(), // button 1
RaisedButton(), // button 2
]
)
In your case you could add a Column around the Row in content and in there add your existing Row and the modified one you created from the above example.
Move buttons to content is a good solution.
showDialog(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return AlertDialog(
title: Center(child: Text('Alert')),
content: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Container(
child: Text(
"message",
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.red,
),
),
),
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
FlatButton(
child: Text('Yes'),
onPressed: () {
Navigator.of(context).pop();
}),
FlatButton(
child: Text('No'),
onPressed: () {
Navigator.of(context).pop();
})
])
],
),
);
});
Changing the theme is a good option.
MaterialApp(
theme: ThemeData(
buttonBarTheme: ButtonBarThemeData(
alignment: MainAxisAlignment.center,
)),
...
Don't add button in actions of AlertDialog. As you can see.
_onSubmit(message) {
if (message.isNotEmpty) {
showDialog(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return AlertDialog(
title: Center(child: Text('Alert')),
content: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children : <Widget>[
Expanded(
child: Text(
message,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.red,
),
),
),
FlatButton(
child: Text('Cancel'),
onPressed: () {
Navigator.of(context).pop();
}),
FlatButton(
child: Text('Ok'),
onPressed: () {
_inputTextController.clear();
Navigator.of(context).pop();
})
],
),
);
},
);
}
}
I use this method to align buttons in actions of AlertDialog.
How this works::
The SizedBox takes the full width of the alertdialog using its context(In the statement MediaQuery.of(context).size.width. After that, a row is used which places space between its children in the main axis(mainAxisAlignment => the x-axis for a row).
AlertDialog style:
AlertDialog(
title: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text('Title'),
CloseButton(
color: Color(0xFFD5D3D3),
onPressed: () {
Navigator.of(context).pop();
})
]),
content: SingleChildScrollView(child: Text("Boby")),
actions: [
SizedBox(
width: MediaQuery.of(context).size.width,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ButtonTheme(
minWidth: 25.0,
height: 25.0,
child: OutlineButton(
borderSide: BorderSide(color: Colors.blueAccent),
child: new Text("Save"),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20)),
onPressed: () {})),
SizedBox(width: 8.0),
ButtonTheme(
minWidth: 25.0,
height: 25.0,
child: OutlineButton(
borderSide: BorderSide(color: Colors.black26),
textColor: Colors.blue,
child: new Text("Close"),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20)),
onPressed: () {}))
]))
]);
Here is the straightforward answer for your problem:
Just use actionsAlignment property of AlertDialog class in flutter. Like so
AlertDialog(
actions: ...,
actionsAlignment: MainAxisAlignment.spaceBetween
)
Or you can use RFlutter Alert library for that. It is easily customizable and easy-to-use. Its default style includes rounded corners and you can add buttons as much as you want.
Alert Style:
var alertStyle = AlertStyle(
animationType: AnimationType.fromTop,
isCloseButton: false,
isOverlayTapDismiss: false,
descStyle: TextStyle(fontWeight: FontWeight.bold),
animationDuration: Duration(milliseconds: 400),
alertBorder: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(0.0),
side: BorderSide(
color: Colors.grey,
),
),
titleStyle: TextStyle(
color: Colors.red,
),
);
And assing your AlertStyle object to Alert's style field.
Alert(
context: context,
style: alertStyle,
type: AlertType.info,
title: "RFLUTTER ALERT",
desc: "Flutter is more awesome with RFlutter Alert.",
buttons: [
DialogButton(
child: Text(
"COOL",
style: TextStyle(color: Colors.white, fontSize: 20),
),
onPressed: () => Navigator.pop(context),
color: Color.fromRGBO(0, 179, 134, 1.0),
radius: BorderRadius.circular(0.0),
),
],
).show();

I am using BottomNavigationBarItem to display bottom navigation UI with icons and text. I would like to be able to add badges with numeric values on those. Here is my current attempt:
bottomNavigationBar:
new BottomNavigationBar(items: <BottomNavigationBarItem>[
new BottomNavigationBarItem(
icon: new Stack(
children: <Widget>[
const Icon(Icons.home),
new Positioned(
top: 0.0,
left: 0.0,
child: new Container(
decoration: new BoxDecoration(
borderRadius: new BorderRadius.circular(4.0),
color: Colors.red),
width: 16.0,
child: new Text(
"12",
style: const TextStyle(color: Colors.white),
),
))
],
),
title: new Text("Home")),
new BottomNavigationBarItem(
icon: const Icon(Icons.star), title: new Text("Star")),
],
type: BottomNavigationBarType.fixed),
However, the badge is positioned with the icon's bounding box, so it overlaps heavily with the icon:
What I would like, instead, is something like that:
Is it possible to achieve this using the BottomNavigationBarItem widget? If not, what would be a good workaround?
make sure that the badge position is right, and the overflowing children should be visible
icon: new Stack(
overflow: Overflow.visible,
children: <Widget>[
const Icon(Icons.home),
new Positioned(
top: -1.0,
right: -6.0,
child: new Container(
decoration: new BoxDecoration(
borderRadius: new BorderRadius.circular(4.0), color: Colors.red),
width: 16.0,
child: new Text(
"12",
style: const TextStyle(color: Colors.white),
),
))
],
),
If it is useful to anyone, I made one that works in the AppBar.
static Widget makeIconWithBadge(String badgeText, GestureTapCallback onTap) {
return Container(
padding: EdgeInsets.only(right: 16.0),
child: Center(
child: new Stack(
overflow: Overflow.visible,
children: <Widget>[
const Icon(Icons.inbox),
new Positioned(
top: -6.0,
right: -6.0,
child: Container(
padding: EdgeInsets.all(2.0),
decoration: new BoxDecoration(
borderRadius: new BorderRadius.circular(99.0),
color: Colors.white,
),
child: new Container(
padding: EdgeInsets.symmetric(vertical: 1.0, horizontal: 4.0),
decoration: new BoxDecoration(
borderRadius: new BorderRadius.circular(99.0),
color: Colors.red),
child: Center(
child: new Text(
"12",
textAlign: TextAlign.center,
style: TextStyle(color: Colors.white, fontSize: 12.0,),
),
),
),
),
),
Positioned.fill(
child: Material(
borderRadius: BorderRadius.all(Radius.circular(99.0)),
color: Colors.transparent,
child: InkWell(onTap: onTap),
),
)
],
),
),
);
}
