Images from Firebase Storage and external web URLs no longer load in app

[vjacobc]

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

All images in my FlutterFlow app have suddenly stopped loading. This includes:

Images hosted on Firebase Storage using valid download URLs with tokens

Images loaded from external secure URLs (e.g. https://e00-elmundo.uecdn.es/...)

Profile pictures and camper images previously working fine

Even though the image URLs open perfectly in a browser, they no longer display in the app. It now shows EncodingError: The source image cannot be decoded.

Expected Behavior

All image URLs (Firebase-hosted and external HTTPS) should be displayed correctly as they were previously. This issue started unexpectedly without any changes to my app configuration.

Steps to Reproduce

1 Upload an image to Firebase Storage under path users/{userId}/uploads/filename.png
2 Get the public download URL
3 Use that URL in an Image.network widget
4 Run the app in FlutterFlow preview or test mode
5 The image fails to load with an “EncodingError” message

Same behavior occurs when using public web image URLs, which worked before.

Reproducible from Blank

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

Environment
FlutterFlow version: Latest (July 2025)
Platform: Web Preview and Test Mode
Browser: Chrome 137.0
OS: macOS Catalina

Additional Information

This issue has stopped the app from functioning properly. It affects both profile and listing images, and completely breaks the UI. The Firebase rules were not changed when this started happening. All images are still accessible directly in the browser, so this seems to be a FlutterFlow rendering or sandbox security issue.

Same issue here. Images from Firebase Storage (uploaded via FlutterFlow) are not displaying in web builds, even after recent patch/update. I've tried:

• Rebuilding the app
• Clearing cache
• Uploading new images
• Testing multiple URLs

This started happening after the latest platform update. This is affecting production users.

Please prioritize this.

Switched on "Advanced Web Settings > Deploy with Firebase" as a precaution, even if it's not needed for Firebase Storage. This helps, interestingly, to retrieve/display from a URL any image that I grab from the web. But Firebase "retrieval" still doesn't work

Please prioritize this! We are a photo app :-)

I'm experiencing the same issue here. I thought I was going crazy last night, but I see that a few others are facing the same issue now.

Greetings! I had the same issue. After a few hours testing image loading, I found this bug report! At least now I know it's a bug and not a development mistake.

[vjacobc]

Update: Several other developers have confirmed they’re experiencing the same issue — Firebase Storage images and external image URLs that previously worked are no longer rendering inside the app.

This seems to be a global problem and is likely affecting many apps built with FlutterFlow.

Please prioritize this fix, as it is currently blocking production apps and user experience.

Thanks for your help!
