How to remove the toast displayed on the Action bar in a flutter on Long hold on back arrow.
In your appBar you can replace the leading parameter by what you want.
Try replacing it with :
AppBar(
leading: IconButton(
icon: Icon(Icons.arrow_back),
onPressed: () {
Navigator.of(context).pop();
},
),
),
It should remove the tooltip. If you want to customize it, see the tooltip parameter of IconButton
Use an IconButton as leading widget of your AppBar like,
Scaffold(
appBar: AppBar(
leading: IconButton(
onPressed: () {
Navigator.of(context).pop();
},
icon: Icon(Icons.arrow_back),
// tooltip: 'Back', // this cause the overlay
),
),
);

How can I change the function of the back button in dart flutter
I really didn't try anything because tbh, i didn't find what to try
You need simply to override the leading property in the AppBar with a new IconButton, then set your specific method:
AppBar(
leading: IconButton(
onPressed: () {
print("clicked");
},
icon: Icon(Icons.abc),
),
),
When navigating between pages in flutter, if the second page has an AppBar, by default the AppBar comes with an IconButton to go back to the previous page. Is there a way to set a custom icon for that IconButton that is different than the one provided by default by Flutter and will be applied to every other page? Kind of like a custom AppBarTheme?
You can remove the BackButton and handling it by yourself, using:
AppBar(
automaticallyImplyLeading: false,
leading: Navigator.canPop(context)
? IconButton(
icon: Icon(
Icons.arrow_back,
color: Colors.black,
size: 47,
),
onPressed: () => Navigator.of(context).pop(),
)
: null,
);
I can't seem to find a parameter that lets the widgets TextButton.icon and ElevatedButton.icon place the label first then the icon. Is there a way or do I have to make a custom widget for this?
Example:
ElevatedButton.icon(
onPressed: () { /* code */ },
icon: Icon(Icons.arrow_forward),
label: Text('Some text'),
)
Both icon & label accepts a Widget. So you could do this:
ElevatedButton.icon(
icon: Text('A'),
label: Icon(Icons.add),
onPressed: () {},
),
flutter, what is the right way to change appbar leading icon at app theme level? so I no need to change on each screen?
I know the following code work for specific screen...
AppBar(
title: Text("Hello Appbar"),
leading: Icon(
Icons.arrow_back,
),
);
but I don't want to do it on each screen, Just checking here if I can set it at app theme level so it is same for all screen...
I referred flutter documentation for appbar, but it was not much helpful.
You can do something like this
import 'package:flutter/material.dart';
AppBar MyAppBar({Widget title, Widget leading}) {
return AppBar(
title: title,
leading: leading,
);
}
Use IconButton to change the leading icon.
AppBar(
title: Text("Hello Appbar"),
leading: IconButton(
onPressed: () {},
icon: Icon(Icons.arrow_back)
),
);
How can I create a FloatingActionButton like in the image?
I tried using FloatingActionButton, but it looks like a whole button with a circle.
I need something like an IconButton as shown in the image.
IconButton will actually deliver the result you are aiming for!
A FloatingActionButton, by guidelines, will always deliver the design you find on your "View in Your Room" titled button.
IconButton(
icon: Icon(Icons.back),
onPressed...
)
You need to use IconButton as below
// Icon Button
new IconButton(
icon: new Icon(Icons.favorite),
tooltip: 'Facorite icon',
color: Colors.blue, //set color which you want
onPressed: () {
// Do your work
},
),
For this, you can use actions ** property of appbar to put icons on the right side of title and **leading property to put a leading icon.
appbar: new AppBar(
leading: new Icon(Icons.search),
actions: <Widget>[
new Icon(Icons.search),
new Icon(Icons.search),
],
title: new Text("title"),
)
I suggest using an Icon inside a GestureDetector widget. This will give you the result you want, but also getting rid of the unnecessary padding around an IconButton.
GestureDetector(
onTap: () {},
child: Icon(Icons.arrow_back, color: Colors.black)
)
