Learn Dart programming the easy way, then build real apps with Flutter. 115 short Dart lessons and a complete Flutter course, with simple examples you can run and edit in the browser and an exercise after every lesson.

Start with Dart Go to Flutter Open the playground

Covers Dart 3 and current Flutter with Material 3. Free, no sign-up, works on any device.

void main() {
  final learners = ['Asha', 'Bikram', 'Chen'];

  for (final (i, name) in learners.indexed) {
    print('${i + 1}. Welcome, $name!');
  }

  final total = learners.length;
  print('$total people started Dart today.');
}

Output

1. Welcome, Asha!
2. Welcome, Bikram!
3. Welcome, Chen!
3 people started Dart today.

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

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

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: Center(child: Text('Hello, Flutter!')),
      ),
    );
  }
}

Result

One codebase. Runs on Android, iOS, web,
Windows, macOS and Linux.

Course 1 Dart course 15 chapters, 115 lessons The language: basics, functions, collections, null safety, OOP, async, Dart 3 features and tooling.

Learn Dart online: a free Dart tutorial for beginners

This Dart tutorial teaches the Dart programming language from zero, then the Flutter framework for building apps for Android, iOS, the web and desktop from one codebase. You do not need any programming experience. Each lesson explains one idea in plain English, shows it in a short Dart example with its output, and ends with an exercise.

It works as a complete Dart programming course: Dart basics to advanced topics, in the right order, written in simple English. It is also the best way to learn Dart for Flutter, because every Flutter app is written in Dart.

Not sure where to begin? Follow the free Dart and Flutter roadmap, or open the Dart online compiler and start typing.

What you will learn

In the Dart course (learn Dart programming):

Dart basics: Dart syntax, variables, data types, strings and string methods, numbers and operators.

Functions and collections: Dart functions, parameters, closures, lists and list methods, sets and maps.
Null safety: How Dart null safety stops null errors before your program runs.
Dart OOP: Classes and objects, constructors, inheritance, interfaces, mixins, enums, generics and extensions.
Modern Dart 3: Records, patterns, switch expressions, sealed classes and class modifiers.
Asynchronous code: Future, async and await, streams, the event loop and isolates.

Questions people ask before starting

What is Dart used for?

Dart is a programming language from Google. It is best known as the language of Flutter, which builds Android, iOS, web and desktop apps from one codebase. Dart is also used for command-line tools and server-side programs.

Is Dart easy to learn for beginners?

Yes. Dart has a clean, consistent syntax, helpful error messages and a type system that catches mistakes while you type. If you have never programmed before, start at chapter 1 of the Dart course and follow the lessons in order. If you know JavaScript, Java, Kotlin or C#, most of Dart will feel familiar.

Should I learn Dart or Flutter first?

Learn the Dart basics first: variables, functions, classes, null safety, collections and async. Every Flutter widget is a Dart class, so Flutter code is much easier to read once you know the language. You do not need to finish the whole Dart course before starting Flutter. The first seven chapters are enough to begin.

How long does it take to learn Dart and Flutter?

With about an hour a day, most beginners finish the core Dart chapters in four to six weeks, and can build simple Flutter apps a month or two after that. Developers who already know another language move faster.

Do I need to install anything to follow these tutorials?

Not to begin. Examples with a Run button open in DartPad, the official online editor, and that includes many Flutter examples. Each course has a lesson on installing the tools on Windows, macOS and Linux when you are ready.

Which versions do the tutorials cover?

The Dart course covers Dart 3, including sound null safety, records, patterns, sealed classes and class modifiers. The Flutter course uses current stable Flutter with Material 3.

Can I build Android and iOS apps with Flutter?

Yes. One Flutter codebase builds apps for Android, iOS, the web, Windows, macOS and Linux. The Flutter course ends with lessons on publishing to Google Play and the App Store.

Is this a complete Dart course?

Yes. The lessons form a complete Dart course from beginner to advanced: syntax, variables, control flow, functions, collections, null safety, OOP, Dart 3 records and patterns, async, files, JSON, HTTP, testing and packages. Think of it as Dart documentation for beginners, with an example and an exercise in every lesson.

Are the tutorials free?

Yes. Every lesson is free to read, with no sign-up and no paywall.

Can I run Dart code online without installing anything?

Yes. The Dart online compiler on this site runs Dart and Flutter code in your browser. Every example with a Run button opens in an editor where you can change the code and run it again.

What is the best way to learn Dart programming?

Follow the lessons in order, type and run every example, change it to see what happens, and finish the exercise at the end of each lesson. Then solve the 30 Dart programming examples and build one small project before moving on to Flutter.

Is Dart similar to JavaScript?

The syntax looks similar and both have async and await, so JavaScript developers learn Dart quickly. The main differences are that Dart is statically typed with sound null safety and compiles to fast native code for Flutter apps.
