What is Flutter Container Height?
Flutter container height is the vertical size of the container widget. We will first see what the default Flutter container height look like and then by using a Flutter example, we will change the height of Flutter container.
Default Flutter Container Height
In order to see the default height of Flutter container, we have to define a simple Flutter container with some width and a background color so we can see if we see a container on our screen with some default height. See the below code:
Container( width: 100, color: Colors.blue )
Container( width: 220, color: Colors.blue, child: Text( 'Flutter container default height', style: TextStyle(fontSize: 18, color: Colors.white), ), )
Change Flutter Container Height
In order to change the Flutter container height, we have to make use of the height constructor of Flutter container widget. This height constructor takes a double(decimal) value but we can pass integer as well(automatically converted).
For demonstration, we have passed a value 100 to the height constructor of Flutter container widget class. See below code:
Container( height: 100, width: 220, alignment: Alignment.center, color: Colors.blue, child: Text( 'Flutter container custom height', style: TextStyle(fontSize: 18, color: Colors.white), ), )
Flutter Container Height Customization 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: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(
height: 100,
width: 220,
alignment: Alignment.center,
color: Colors.blue,
child: Text(
'Flutter container custom height',
style: TextStyle(fontSize: 18, color: Colors.white),
),
),
],
)),
));
}
}Conclusion
In conclusion, I have practically implemented the customization of Flutter container height. I would love to have your feedback on this post.
