Check the following links for the system requirements for your operating system before you start.
Note: you will require access to a MacOS to be able to build for iOS or use an online CI
Have at least one of the following:
- A device connected to your SO, an Android or an iOS
- Android emulator.
- iOS emulator.
Go to the oficial website flutter.dev for installation instructions. Start by picking your operating system of choice.
Install https://flutter.io/docs/get-started/install
Note: While Flutter relies to have full Android Studio installed because of dependencies, you do not need to develop Flutter in it. In fact our editor of choice will be Visual Studio Code.
The editor of choice will be Visual Studio Code ( install ), there are instructions in the oficial website, make sure you install the Flutter and Dart plugin for VSCode.
Install VSCode: https://flutter.io/docs/get-started/editor?tab=vscode
We also recomend that you install the following plugins.
- For Workshop: Live Share
- Awesome Flutter Snippets - Just a bunch of more common snippets shortcuts
- GitLens - Git helper to better version your work
- Rainbow Brackets - Makes the brackets colorful and easier to track (you'll need it)
- Pubspec Assist - Helps add new dependencies
- dart-import - Turns your imports to relative paths
Run command flutter doctor in your console and you should have mostly everything with a green check mark.
Troubleshooting:
- Have at least one toolchain for developing iOS or Android
- Having 'licensing problems' you can try the command
flutter doctor --android-licenses - It's recommended that you to use Java 8, for set up you can install SDKMAN
- Problems using the android emulator? Don't for get to set ut the
$ANDROID_SDK_ROOT - If you are using and android connected over USB and it is not detected:
- Install "Android File Transfer"
- Check for your model if need any software installed
- Restart the ADB by running the following command
adb kill-server - Try a different USB cable
While we will be developing in Dart, if you are experienced developer in another programming language, you will find it easy to start. We will mostly use Flutter Widgets but if you would like to know more about Dart, or if you need to learn how to do something in Dart. I recommend you check the following websites
- Learn X in Y minutes (Dart) - https://learnxinyminutes.com/docs/dart/
- Dartlang Language Tour - https://www.dartlang.org/guides/language/language-tour
- Dartlang Samples - https://www.dartlang.org/samples

Thanks these setups are essential for any workshop. Prior to the day of event, it is highly recommended that users get these tools up and running.
