In this post, we'll be creating a simple social network, called Stream Flutter, that allows a user to post messages to followers, chat either 1-on-1 or in groups.

Stream's Activity Feed API and Chat API combined with Google's Flutter makes it straightforward to build this sort of complex interaction. All source code for this application is available on GitHub. This application is fully functional on both iOS and Android.

For brevity, when we need to drop down to native code, we'll only focus on Android (Kotlin). You can find the corresponding iOS code to see how things are implemented.

Part 3 contains the final product. If you'd like to skip the tutorials and see the end result, please see the README.md in the backend and frontend directories on that branch to get going. You can find each part of this series by the corresponding git branch or click a link below:
