Flutter floating action button position fixed

Flutter Floating Action Button Position Fixed:

In Flutter, you can set the position of a Floating Action Button (FAB) as fixed by using the Stack widget along with the Positioned widget. The Stack widget allows you to stack multiple widgets on top of each other, while the Positioned widget helps in specifying the position of a widget within a Stack.

Here’s an example of how you can set the position of a FAB as fixed:


import 'package:flutter/material.dart';

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Fixed FAB Position'),
),
floatingActionButton: Stack(
children: [
Positioned(
bottom: 16.0, // set the bottom position
right: 16.0, // set the right position
child: FloatingActionButton(
onPressed: () {},
child: Icon(Icons.add),
),
),
],
),
body: Center(
child: Text(
'Floating Action Button Position Fixed Example',
),
),
),
);
}
}


In the above example, we wrap the FloatingActionButton with a Stack widget and place a Positioned widget inside the Stack. We set the desired bottom and right values for the Positioned widget to position the FAB at a fixed location on the screen.

The FloatingActionButton is triggered by the onPressed callback, which can be replaced with your own logic or function to perform specific actions when the button is pressed.
