Modal routes

Routes marked modal=True are rendered as fullscreen-dialog overlays on top of the previous location's view stack. Closing the modal pops it without rebuilding the views underneath.

This example demonstrates both modes:

• /settings — a global modal declared at the top level. Reachable from /, /items, /items/<id> — closing returns to whichever URL was active when it opened. Deep-linking to /settings directly defaults the base to /.

• /items/<id>/edit — a local modal declared as a child of /items/:id. The URL embeds the item id, so deep-linking restores the full stack [ItemList, ItemDetails(id), EditItemModal] from URL alone.

Run

flet run

What to try

1. From Home, tap "Open Settings" → modal slides up over Home. Close → back to Home with no rebuild.
2. Navigate Home → Items → Apples → tap "Edit" → local modal slides over the Apples detail view. Close → back to Apples with the detail view still mounted.
3. From Apples detail, tap "Open Settings" → modal slides up over the detail. Close → back to Apples detail (not Home).
4. Paste /items/2/edit into the URL — the stack rebuilds and the modal opens directly. Close → /items/2.
