and rewrote the component's network requests.
showSimpleSnackbar, allows displaying a simple snackbar,
with text and one action button, that can be clicked.
doNetworkRequest is supposed to be a wrapper for the
already existing post* functions.
It aims to make network requests and error handling easier,
by containing all the try&catch blocks
and being able to show snackbars.
Work already done:
- moving the New Room screen to a different endpoint
- fetching public rooms using the post API
- displaying public rooms
Suggestion for user interaction:
1. click on room
2. open bottomSheet with information and join button
3. click "join" to join room
NOTE: Might be a good idea to move the title down,
if no description is available.
If ListTile does not support such feature,
maybe using an alternative might be good idea
