WANT TO SUCCEED TO IMPLEMENT

[creamintea]

Hello, I am a university student from China. We need to complete a course assignment to create an app similar to WeChat. I would like to make some changes to your open-source project and add additional features, such as user management, etc. I am currently on step five, which is running flutter run, but I haven't been able to complete this task due to slow internet. Maybe I will be able to do it once my internet speed improves.

I want to ask: I am a beginner in communication technologies. Could you tell me what each folder is for in the project? Also, which files do I need to edit to implement the functionality I need?
