Column Widget :

• Column widget is one of Flutter application's most commonly used layout patterns. It is a multi-child widget that displays its children in a vertical array. This widget is widely used to create user interfaces with multiple components organized in a vertical arrangement. Its main-axis alignment is vertical, as shown in the below image:

• The Column widget provides a constructor with various parameters to customize its behaviour and layout.

Example :

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(title: const Text('Flutter Column Widget')),
      body: Column(
        children: [
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.brown),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.yellow),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.brown),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.yellow),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.orange),
        ],
      ),
    ),
  ));
}

Output :

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(title: const Text('Flutter Column Widget')),
      body: Column(
        mainAxisAlignment: MainAxisAlignment.spaceAround,
        crossAxisAlignment: CrossAxisAlignment.center,
        textDirection: TextDirection.ltr,
        children: [
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.brown),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.yellow),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.brown),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.yellow),
          const Text('Hii This is a Column widget  '),
          Container(height: 100, width: 100, color: Colors.orange),
        ],
      ),
    ),
  ));
}
