I am trying to have multiple floatingActionButtons on a page in a flutter app, but I haven't been able to solve myself as the instructions on the internet aren't clear. I want the floating action buttons to be on the bottom right of the app. The current code correctly has two floatingactionbuttons, but they appear at the top right. Can someone please let me know how to do this. Thanks! Here is my curret code that puts two floatingactionbuttons in the top right but I want them in the bottomright.
#override
Widget build(BuildContext context) {
return new Scaffold(
floatingActionButton: Column(
children: <Widget>[
FloatingActionButton(
heroTag: "btn1",
child: Icon(Icons.add),
onPressed: () {
setState(() {
list.add(list.length);
});
}),
FloatingActionButton(
heroTag: "btn2",
child: Icon(Icons.add),
onPressed: () {
setState(() {
list.add(list.length);
});
}),
]), //column end
You can use something like this:
floatingActionButton: Stack(
children: <Widget>[
Padding(padding: EdgeInsets.only(bottom:80),
child: Align(
alignment: Alignment.bottomRight,
child: FloatingActionButton(
heroTag: "btn1",
onPressed: (){},
child: Icon(Icons.camera_alt),),
),),
Align(
alignment: Alignment.bottomRight,
child: FloatingActionButton(
heroTag: "btn2",
onPressed: (){},
child: Icon(Icons.add_photo_alternate),),
),
],
)

I am new to flutter and I was wondering if someone can help me with my row of buttons. They both work outside of the row but not within it. I have attached the code below please let me know if you can help or need more information.
Expanded(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
IconButton(
icon: Icon(Icons.edit),
)
floatingActionButton: FloatingActionButton(
child: Icon(Icons.add),
onPressed: () async {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => StudyPage(
title: 'Add a study',
selected: 0,
),
),
);
},
),
],
)
],
),
I little modified your (Row) code as follows and now it works.
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
IconButton(
icon: const Icon(Icons.edit),
onPressed: () {},
),
FloatingActionButton(
child: const Icon(Icons.add),
onPressed: () async {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => StudyPage(
title: 'Add a study',
selected: 0,
),
),
);
},
),
]),
As far as I know, you can try this
Row(children:[
Expanded(
child:
IconButton(
icon: Icon(Icons.edit),
)),
Expanded(
child:
IconButton(
icon: Icon(Icons.edit),
)),
]);
if it solve your problem, kindly accept it as an answer so that others will get help
First. Expanded only work when place inside Colum/Row children.
Expanded will take all space of parent Colum/Row and expand Colum/Row size it possible.
If you want Colum/Row to max size, try add mainAxisSize: MainAxisSize.max to Colum/Row instead.
Second. Your code look like has error when floatingActionButton not is a Widget when you place in Colum/Row children, it is a props of Scaffold. Try to replace it by a valid button like IconButton/ElevatedButton/etc.... Your IconButton missing onPressed too.
Example:
Row(
mainAxisSize: MainAxisSize.max,
children: [
Expanded( // Place `Expanded` inside `Row`
child: ElevatedButton(
child: Text('First button'),
onPressed: () {}, // Every button need a callback
),
),
Expanded( // Place 2 `Expanded` mean: they try to get maximum size and they will have same size
child: ElevatedButton(
child: Text('Second button'),
onPressed: () {},
),
),
],
)
I have a problem where If I wrap my FABs placed a the end of a BottomNavigationBar in a Column, It changes their positions. I don't want to wrap it in a stack because than it is unclickable, I tried various ways to fix that, but none of them worked.
FAB 1:
Widget add(){
return new FloatingActionButton(
onPressed: (){Navigator.push(context, new MaterialPageRoute(builder: (context) => HomePage()));},
heroTag: 'btnAdd',
child: new Icon(Icons.add),
backgroundColor: Colors.blue,
elevation: 0.0,
splashColor: Colors.redAccent,
);
}
FAB 2:
Widget floatMain(){
return new FloatingActionButton(
heroTag: 'btnMain',
child: new AnimatedIcon(
icon: AnimatedIcons.menu_close,
progress: _animateIcon,
),
tooltip: 'floatMain',
onPressed: animate,
backgroundColor: _buttonColor.value,
);
}
FAB Call:
floatingActionButton: new Container(
child: new Stack(
children: <Widget>[
new Container(
child: new Transform(
transform: Matrix4.translationValues(0.0, _translateButton.value - 56, 0.0),
child: add(),
),
),
floatMain(),
],
),
),
floatingActionButtonLocation: FloatingActionButtonLocation.endDocked
So, if I wrap it in a Stack it works, but it doesn't work with a Column.
If you need only FAB button buttom right align. Inside column
Try it.
Expanded(
child: Align(
alignment:FractionalOffset.bottomRight,
child: Padding(
padding: EdgeInsets.only(bottom: 10.0),
child: floatMain()//Your FAB widget here,
),
),
),

I am integrating google and facebook sign in to single page.I've set google sign in btn in container. Plz let me know where can I put fb login button with login-logout condition in same container. here's my code.
Widget build(BuildContext context) {
// TODO: implement build
return MaterialApp(
home: Scaffold(
body: Container(
child: _isLoggedIn
? Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Image.network(_googleSignIn.currentUser.photoUrl, height: 50.0, width: 50.0,),
Text(_googleSignIn.currentUser.displayName),
OutlineButton( child: Text("Logout"), onPressed: (){
_logout();
},)
],
)
: Center(
child: OutlineButton(
child: Text("Login with Google"),
onPressed: () {
_login();
},
),
) ,
),
),
);
}
Center(
child: Row(
mainAxisAlignment:MainAxisAlignment.spaceEvenly,
children:[
OutlineButton(
child: Text("Login with Google"),
onPressed: () {
_login();
},
),
OutlineButton(
child: Text("Login with Facebook"),
onPressed: () {
//Todo
},

How can I make a clickable widget with a ripple and a button inside?
Here is the code I have:
Material(
child: InkWell(
onTap: () {},
child: Column(
children: <Widget>[
Text("this column is clickable"),
IconButton(
icon: Icon(Icons.airplanemode_active),
onPressed: () {},
),
]
)
)
),
When clicking on the Column, everything works fine, the ripple effect go behind the IconButton as expected. But when clicking on the IconButton, the onPressed trigger is called but it also activates the InkWell. Is there a way to prevent in from activation the InkWell?
Put Column widget inside GestureDetector and set excludeFromSemantics: true like the following:
Material(
child: Padding(
padding: const EdgeInsets.all(40.0),
child: InkWell(
onTap: () {},
child: GestureDetector(
excludeFromSemantics: true,
child: Column(
children: <Widget>[
Text("this column is clickable"),
IconButton(
icon: Icon(Icons.airplanemode_active),
onPressed: () {},
),
]
),
)
),
)
),
Its from this github post.
Let's say that I have this widget:
Card(
child: InkWell(
onTap: () {},
child: Padding(
padding: const EdgeInsets.all(28.0),
child: RaisedButton(
child: Text('Test'),
onPressed: () {},
),
),
),
),
I would like to disable (prevent showing) ripple effect on Card/InkWell only when the RaisedButton is tapped, but to show it when the Card is tapped (i.e. outside the button). Is there any way to achieve this effect?
I think the generalized question can be: How to prevent ripple effect on surrounding InkWell when tapped on InkWell inside? If you take a look at the source code then you can see that RaisedButton has Material and InkWell widgets that cause ripple.
Here is the full sample code.
If you want a quick hack, check it out:
Container(
width: 180,
height: 120,
child: Stack(
children: <Widget>[
Card(
child: InkWell(
onTap: () {},
),
),
Center(
child: RaisedButton(
child: Text('Test'),
onPressed: () {},
),
)
],
),
)
You can handle the logic inside onHighlightChanged method;
Color _color;
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Center(
child: Card(
child: InkWell(
splashColor: _color,
highlightColor: _color,
onTap: () {},
child: Padding(
padding: const EdgeInsets.all(28.0),
child: RaisedButton(
onHighlightChanged: (value) {
if (value) {
setState(() => _color = Colors.white);
} else {
Timer(Duration(milliseconds: 200), () {
setState(() => _color = null);
});
}
},
child: Text('Test'),
onPressed: () {},
),
),
),
),
),
);
}
