So non of this worked for me. After a while, I finally figured how to make it work. My project name has an underscore ie: project_name, so I changed it to projectname. And I realised my package id is still the same either ways hence somehow there is a conflict with how firebase references files. Not sure and don't know why this is happening.

Updating pod was not enough for me.

I need to replace the content of my Podfile with Podfile-ios-objc. https://github.com/flutter/flutter/blob/master/packages/flutter_tools/templates/cocoapods/Podfile-ios-objc

Than it worked.

Answer 3

I had the same problem all day long. I ended up having to bump my version of Firebase_Auth to the latest, which for me at the moment is: ^0.15.3, which then forced me to have to upgrade Flutter as well.

Did the typical

Delete PodFile and PodFile.lock Flutter Clean pod install

I'm using Mac, so I also had to update my Xcode to 11.3. Then needed to update Mac OS to Catalina.

Lot's of work, but this got me to a successful build. Hopefully, something in here helps others dealing with this issue.

Update your pod. Your pod is not on the latest version
