Current Behavior
A ListView is bound to a Backend Query (Collection: packages, Query Type: List of Documents, Firestore). The query returns data correctly — 6 documents confirmed present in Firestore via the Firestore Data Manager. However, no items render in Test Mode: the screen stays empty except for the AppBar/page title and search bar. Browser console shows: Uncaught TypeError: J.c1(...).al is not a function in main.dart.js.
Expected Behavior
The ListView should render one child per document returned by the Backend Query (6 ServiceCard items), reflecting the real data in Firestore.
Steps to Reproduce
- Create a Firestore collection ("packages") with several documents (String/Boolean fields).
- Add a ListView to a page, attach a Backend Query (Query Collection, List of Documents) pointing to that collection, no filters/limits.
- Add a component instance inside the ListView as the model child, bind its fields to the document properties.
- Run the app in Test Mode.
- Observe: the list stays empty, no error shown in the FlutterFlow UI, but the browser console shows "Uncaught TypeError: J.c1(...).al is not a function".

Additional Information
This blocks displaying our service catalog to end users — a core feature of an app currently in development (premium auto-detailing booking app). We've verified Firestore rules allow read access, verified the data exists (6 documents), and rebuilt the widget from scratch (deleted and recreated as a fresh ListView) — same result every time. A related community post with an identical symptom (same TypeError), published early August 2026, remains unresolved: https://community.flutterflow.io/ask-the-community/post/gridview-listview-bound-to-backend-query-shows-no-data-in-run-test-mode----SACeGX45nQ0qDl6
