It depends on what part you want to contribute to. If you want to contribute to just the framework, you can follow the Setting up the framework development environment instructions.

If you also want to make changes to the engine too, you'll need to follow the Setting up the engine development environment instructions first.

There's also a #hackers-new channel on the Flutter contributor's Discord where you can ask questions about contributing to flutter/flutter or setting up your environment. https://flutter.dev/chat has the link to join there and other information. I check there as well, so if you have any specific issues running it on your system, feel free to ping me there :)
