1. Stage 1
Flutter UI already done.
And backend api is already done.
You just need to connect it to the UI so flutter app can be work by functional with backend functions.
Importantly, you should know or have experience or confident on this part.
In this app there is chat section. (Not audio or video call include) Only chat and sending file etc.
You need to do it with XMPP service or protocal. There are many sample codes in the google so you can find it well or study about it if you don't know.
It will be good if this is help for you. [login to view URL]
