Codelabs

The Flutter codelabs provide a guided, hands-on coding experience. Some codelabs run in DartPad—no downloads required!

Good for beginners

If you’re new to Flutter, we recommend starting with one of the following codelabs:

  • Building your first Flutter app (workshop)
    An instructor-led version of our very popular “Write your first Flutter app” codelab (listed below).

  • Your first Flutter app
    Create a simple app that automatically generates cool-sounding names, such as “newstay”, “lightstream”, “mainbrake”, or “graypine”. This app is responsive and runs on mobile, desktop, and web. (This also replaces the previous “write your first Flutter app” for mobile, part 1 and part 2 codelabs.)

  • Write your first Flutter app on the web
    Implement a simple web app in DartPad (no downloads required!) that displays a sign-in screen containing three text fields. As the user fills out the fields, a progress bar animates along the top of the sign-in area. This codelab is written specifically for the web, but if you have downloaded and configured Android and iOS tooling, the completed app works on Android and iOS devices, as well.

    Start with a simple app that manages state with the Provider package. Unit test the provider package. Write widget tests for two of the widgets. Use Flutter Driver to create an integration test.

Writing platform-specific code

Learn how to write code that’s targeted for specific platforms, like iOS, Android, desktop, or the web.

  • How to write a Flutter plugin
    Learn how to write a plugin by creating a music plugin for iOS and Android that processes audio on the host platform. Then make an example app that uses your plugin to make a music keyboard.

  • Using a plugin with a Flutter web app
    Finish an app that reports the number of stars on a GitHub repository. Use Dart DevTools to do some simple debugging, and host your app on Firebase and, finally, use a Flutter plugin to launch the app and open the hosted privacy policy.

  • Write a Flutter desktop application
    Build a Flutter desktop app (Windows, Linux, or macOS) that accesses GitHub APIs to retrieve your repositories, assigned issues, and pull requests. As part of this task, create and use plugins to interact with native APIs and desktop applications, and use code generation to build type-safe client libraries for GitHub’s APIs.

  • Adding a Home Screen widget to your Flutter app
    NEW Learn how to add a Home Screen widget to your Flutter app on iOS. This applies to your home screen, lock screen, or the today view.
