AssetManifest.bin.json 404 on ALL projects (including brand new blank ones) - breaks fonts and default icon

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

Getting a 404 error for assets/AssetManifest.bin.json on every project I open in FlutterFlow, including a brand new blank project created just now with zero custom widgets added.

This causes:

• google_fonts failing to load the default font "InterTight-SemiBold"
• The default flutterflow_icon.png failing to load (404) from the app manifest
• Pages render only the header/AppBar, then stop - no widgets/fields/buttons appear below it, even on pages that previously worked fine

Confirmed this is NOT project-specific. I tested identically on:

1. My original project (FixHo)
2. A duplicated clone of that project
3. A brand new blank test project (TEST123) with nothing built

All three show the exact same console errors and the exact same blank-page rendering failure.

Also tried: hard refresh (Ctrl+Shift+R), clearing site data via DevTools > Application > Clear storage, testing in a fresh Incognito window, and a full Run/rebuild. None of these resolved it.

Checked status.flutterflow.io - shows 100% operational, so this isn't reflected on the status page.

Expected Behavior

The app preview should load and render all page widgets normally (buttons, text fields, dropdowns, images etc.) without any 404 errors for AssetManifest.bin.json, and the default font (Inter Tight) and default app icon should load successfully, as they did before this issue started occurring.

Steps to Reproduce

1. Open FlutterFlow and create a brand new blank project (or open any existing project).
2. Click "Run" to launch the preview, without adding any custom widgets.
3. Open browser DevTools (F12) and check the Console tab.
4. Observe a 404 error for assets/AssetManifest.bin.json.
5. Observe that google_fonts fails to load the default font "InterTight-SemiBold" due to the same missing AssetManifest.bin.json.
6. Observe the default flutterflow_icon.png also fails to load (404) from the manifest.
7. On pages with widgets/fields (e.g. a form with text fields and buttons), observe that only the page header/AppBar renders - all widgets below it fail to appear.

This was reproduced identically on: an existing project (FixHo), a duplicated clone of that project, and a brand new blank test project (TEST123) with zero custom widgets added.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Visual documentation

Environment

- FlutterFlow version: Latest (as of July 2026)
- Platform: Web
- Browser name and version: Google Chrome (latest)
- Operating system and version affected: Windows

Additional Information

This is blocking all testing and development on my project. I am building FixHo, a service ticket management app, and cannot verify any page functionality (including Supabase data connections and button actions) because pages fail to render past the header. I've already tried a duplicated project clone and a brand new blank project - same failure on all three. Please investigate as a priority since this affects basic app preview functionality, not just my specific project.

Hi! Sorry to hear you're experiencing this issue.

Unfortunately, I'm not able to reproduce the error on my end. It might be something specific to your configs.

In this case, I recommend reaching out to support via the in-app chat or by email at support@flutterflow.io . They have the tools and access needed to take a closer look at your specific case.

@snehelectricalksp-ctrl the AssetManifest.bin.json issue should be fixed now, could you please check it's resolved for you?

[snehelectricalksp-ctrl]

Thanks for the fix — confirmed AssetManifest.bin.json now loads (200 status). However, the app screen is still blank on every page, including HomePage with no custom logic. Console shows: Uncaught TypeError: Cannot read properties of null (reading 'i') at main.dart.js:170. Reproduced in Incognito with no extensions, fresh login.
