How can I give a border to the container in Flutter?

In the context of mobile development or application development there is an easy way named “decoration” property and the “BoxDecoration” class for bordering the “container”.

Here is the example given of how you can create a birder around the bubble of chat for income messages in your messaging application:-

Import ‘package:flutter/material.dart’;
Void main() {
  runApp(MyApp());
}
Class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    Return MaterialApp(
      Home: Scaffold(
        appBar: AppBar(
          title: Text(‘Incoming Messages’),
        ),
        Body: Center(
          Child: Padding(
            Padding: EdgeInsets.all(8.0),
            Child: Container(
              Padding: EdgeInsets.all(12.0),
              Decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(8.0), // Optional: Add rounded corners
                border: Border.all(
                  color: Colors.blue, // Choose your desired border color
                  width: 1.5, // Choose your desired border width
                ),
              ),
              Child: Text(
                ‘Hey! How are you?’,
                Style: TextStyle(fontSize: 16.0),
              ),
            ),
          ),
        ),
      ),
    );
  }
}

This above code will wrapped with “padding” to the “container” so that it can have some space. Then the “box decoration” would define the border with your desired color, width, and optional rounded corners if you want.
