Hello @bettkipronoh, sorry for the late response what is the plugin version you are using? also is it possible to provide me with the link you requested to download & device info (sdk version at least)

bettkipronoh commented 3 weeks ago

Hello @abdallah-odeh , Am using flutter_file_downloader: ^2.0.0 Unfortunately I can't provide the url because the exception was caught by firebase crashlytics from a user's device.

I'll investigate in the bug and tell you what I found Thanks for reporting

Hello @bettkipronoh, did you face this issue a lot? actually I could not figure out the cause of the bug so I wrapped it with try & catch to avoid app to crash

bettkipronoh commented 1 week ago

Yes many users are affected. Here is firebase screenshot Once you publish it i will update the app and let you know. Screenshot from 2024-09-04 16-03-08

Sorry to hear that, I will deploy a version today that avoids app crash, I believe that the file get downloaded indeed but the callback never gets fired; so basically the code sees the task still in progress

I deployed a new version flutter_file_downloader: ^2.0.1-dev.2, please try it out & tell me if works fine to roll it to production
