Planned Flow (unimplemented):
- create new category on /edit-category page using bottom-right fab
- sort categories using the two-line hamburger-style menu on each item
- click on a category to modify/delete it
NOTE: maybe on a different screen or MBS?
Translations are provided in *.arb* format.
Some keys have descriptions
(indicated by leading @-symbol).
Descriptions should not be copied into the translation itself.
Currently only English is supported (app_en.arb),
but German is planned.
Apparently weblate merged .arb support at some time,
so it would be nice to enable community translations at some point.
The screen allows every room member,
to view a list of other room members,
and their role (Owner, Admin or Member).
If the user is allowed
(Owner, Admin, changeAdmin/manageMembers),
to either kick or promote members to the admin role,
the list tile will have a tap event.
NOTE: This is why some members do not have a hover animation.
For example the owner cannot be kicked.
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.
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.
