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.
