In this Flutter post, we will be implementing Flutter container full width with the help of a proper and easy Flutter example for better understanding. After reading this post, you won’t find any problems related to the implementation of Flutter container full width. So let’s get right into its implementation phase.
What is Flutter Container Full Width?
Flutter container full width is making the width/horizontal size of the Flutter container widget to match the screen width size. It is used to adjust the width of the Flutter container widget with different screens width. Let’s now implement it using a proper Flutter example.
Implementing Flutter Container Full Width
To give the Flutter container a full width, we first have to use the width constructor of the Flutter container widget class and pass it double.infinity. It is used to be as big in height or width as the parent allows. See the below code:
Container( height: 50, width: double.infinity, color: Colors.green)

Flutter Container Full Width Implementation Source Code
import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: Homepage(), ); } } class Homepage extends StatelessWidget { @override Widget build(BuildContext context) { return SafeArea( child: Scaffold( body: Center( child: Container( width: double.infinity, height: 50, alignment: Alignment.center, color: Colors.blue, child: Text( 'Flutter Container Full Width', style: TextStyle(color: Colors.white), ), ), ))); } }
