Using this solution can temporarily solve the problem #11300 (comment)

@mdddj
Are you using any other community package just like the comment here #11300 (comment) ?

Running into the same issue since yesterday. Manually editing .pub-cache/hosted/pub.dev/firebase_auth-4.7.2/ios/Classes/messages.g.m and changing the import statement allows the build to run successfully. Given that the problem was already discussed and fixed for other files here #11300 (comment) the issue seems pretty obvious?

I would create a PR but messages.g.h seems to be autogenerated and I do not know enough about Pigeon to know how to fix it. Seems the issue was fixed but reintroduced here #10802.

Changes needed in messages.g.m to fix the build manually:

#import <firebase_auth/messages.g.h>
#if TARGET_OS_OSX
#import <FlutterMacOS/FlutterMacOS.h>
#else
#import <Flutter/Flutter.h>
#endif

@mdddj 您是否使用任何其他社区包，就像这里的评论#11300（评论）一样？

Yes, I found it

The issue is reproducible using the steps below

• flutter create foo & cd foo
• flutter pub add firebase_core firebase_auth file_selector
• flutter build ios (you may need to select a dev team in xcode first)
