Unable to Access Uploaded File URL or Create App State Variable After Firebase Upload

Database & APIs

I'm trying to allow users to upload a campaign image, save it to Firebase Storage, and then store the returned download URL in Firestore as part of a form submission.

The image uploads successfully using the “Upload media to Firebase” action inside the Action Flow Editor. However, I’m unable to retrieve the returned file URL to assign it to a field (like campaignImage) because:

There is no option for "Return Uploaded File URL", “Set Variable,” or “Assign Variable” in Action Flow Editor.

I tried to use "Set Form Field" or "Update App State" actions after the upload, but:

The campaignImage field doesn't show up under Set Form Field.

“Update App State” prompts me to add app state variables first, but I can’t find any section in the current FlutterFlow interface that lets me create app state variables. The App State option mentioned in past tutorials and help docs does not exist in the App Settings or anywhere else in the UI.

What have you tried so far?

  • Configured image upload widget with Firebase Storage (upload works ✅).

  • Used the Action Flow Editor to chain a second action after upload.

  • Scanned all possible action types in Action Flow Editor including “Set Form Field,” “Update App State,” and “Execute Callback.”

  • Reviewed FlutterFlow docs and tutorials like Getting Output from Custom Widgets — but the UI for App State management seems to be missing in my workspace.

  • Tried searching “App State” in the Help search bar (shows results, but no visible location to add App State variables).

  • Shared detailed screenshots across app settings, action flow editor, and dropdowns.
