Encountering ProgressEvent Issue in Flutter Web App with Firebase

Developed a Flutter application with a Firebase backend. On Android, uploaded images display correctly, but the web version shows an [object ProgressEvent] error. Modifications to Firebase rules and incognito or alternate browser tests did not resolve the problem.

hey, i experenced a similar issue w/ my flutter web and firebase. i ended up troubleshooting cors settings after checking network logs. did u try experimenting with diff configuration? would love to hear how u solved it if u found a workaround.

Based on my experience, this error often results from a mismatch in how the web version handles asynchronous file uploads compared to mobile. I discovered that certain initialization steps were omitted in the web configuration, particularly related to secure storage and proper endpoint designation. Adjusting these settings, along with thorough device-specific testing using detailed Firebase logs, helped identify and resolve any hidden misconfigurations. Ensuring that web-specific settings align with mobile configurations, but with additional web security nuances in mind, ultimately led to a more stable implementation.

hey, try rechecking firebase init- cfg for web. i had a similar issue when my storage config was outdatd. fixing that helped a lot, so maybe resetting it will work for u too.
