Padding

Part of the Your First App section of Coddy's Flutter journey. Lesson 17 of 32.

A box that hugs its text looks cramped. padding: adds space inside the box, between its edge and its child:

Container(
  padding: EdgeInsets.all(16),
  color: Colors.yellow,
  child: Text('Room to breathe'),
)

EdgeInsets.all(16) means 16 pixels on all four sides. EdgeInsets.symmetric(horizontal: 24, vertical: 8) sets the sides and the top and bottom apart.

A Container also has margin:. That is space outside the box, between it and its neighbors. The colored part does not grow.

Challenge

Easy

Give Fresh some room: add 24 pixels of padding on every side, inside the green box.

Try it yourself

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: Container(
            color: Colors.lightGreen,
            child: Text('Fresh', style: TextStyle(fontSize: 32)),
          ),
        ),
      ),
    );
  }
