Implement search user
🚀 Feature Proposal
As a user, I want to have the option to search for a registered user by his/her username. When typing the characters, I want to see matching users. There should be a possibility to add the searched user as a friend, if he/she isn't already a friend of mine, or to see an indication that he/she is already a friend of mine.
Motivation
Searching and adding friends is acore feature of the Akamu App.
Technical Details
You can orientate on the Android Akamu App. There should probably be a button for adding as friend. When this "add as friend" request was successful, change the button to a text or an icon that indicates that this was successful. If there was an error, you could show a snackbar or toast.
The searching could be initiated by tapping on an floating action button with a lens icon or maybe even some additional hint text that says "Search" or so...
