PR Content

Add a loading tab to the room_screen page to handle the transition when users click to navigate to another page.

PR Feature

• Supports the loading status of multiple pages.
• Prevents duplicate requests when users repeatedly click on the same content.
• Supports modifying the text content and details content during loading.

How to Use

Use the following code anywhere within your room screen pages:

show_room_loading_tab(
      loading_tab_live_id(room_alias.alias()),
      “Loading...”,
      Some(“Loading...”.to_string()),
      Some(“Loading Room Alias...”.to_string()),
);

Hide and close the loading tab with the given id, if it exists, use hide_room_loading_tab(tab_id: LiveId)

do we not have this already, with the restore_status_view? Or this is meant as a replacement for restore_status_view?

Either way, we should just have one widget that offers this. I do agree with your approach that it should be a separate widget (instead of duplicating it in both the InviteScreen and the RoomScreen), and that's been on our to-do list for a while, so perhaps that's why you filed this PR.

Thus, go ahead and modify the code to use your LoadingScreen everywhere instead of the restore status view within the InviteScreen & RoomScreen. Otherwise it'll be too difficult to maintain two different versions of the same thing.

EDIT: now we have another screen where this should be used too, the SpaceLobbyScreen. So the new LoadingScreen can be shown in place of either the RoomScreen, InviteScreen, or SpaceLobbyScreen while they are waiting to be received from the homeserver.
