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.
NOTE: Only the room owner can delete a room,
but they are not able to leave the room.
BUG: Deleting or leaving the room deletes the room from disk,
but for an unknown reason, the homescreen does not update
and still shows the room.
Opening and closing the room seems to cause the homescreen to
update, removing the room.
In preperation for upcoming room screens.
RoomInfo is supposed to be used in conjunction with
the Room class.
They are not merged (Room as a attribut in RoomInfo),
because whilst Room can be stored on disk,
RoomInfo can not.
This is done to prevent tampering with the data
(when offline).
This also makes hiding elements easier when the user is offline,
as we can just pretend, that they do not have the required permission.
Done in preperations for rooms,
and the ability to edit rooms.
Will later be used to hide/show certain elements,
when the user does not meet the criteria
(permissions / admin / owner)
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
If the room was created successfully,
the wizard automatically saves the room data on disk.
This allows it to be cached,
even if the user loses internet connection
right before the wizard exists.
That way the room will be cached.
This is prevents the current route from being reset,
when reloading the tab
and also prevents the welcome screen from showing
(when running on slow connections)
NOTE: This also means that the home screen will be loaded
even if the client has never been logged in.
This means that some functions might return null
