[firebase_auth] Cannot build for MacOS

[PieterAelse]

When building my app for MacOS using firebase_auth 15.5.+2 (latest) I get a CompileC error:

[laptop_name]:[folder] pieter$ flutter run

Launching lib/main.dart on macOS in debug mode...
** BUILD FAILED **

The following build commands failed:
CompileC /Users/pieter/[app_path]/build/macos/Build/Intermediates.noindex/Pods.build/Debug/firebase_auth.build/Objects-normal/x86_64/FLTFirebaseAuthPlugin.o /Users/pieter/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.15.5+2/darwin/Classes/FLTFirebaseAuthPlugin.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

Using a pre-MacOS support version, eg 0.15.4, the build succeeds (but later the app crashed on a MissingPluginException of course)

Might be related to issue #2097

I have the same issue. There is a problem with the UserAgent.h. PR for this fix: #2099

For me the workaround was to pin version of firebase_auth and firebase_core to 0.15.3 and 0.4.4 respectively.

It seems that firebase_core 0.4.4+2 is breaking auth by bumping firebase_core_platform_interface to the latest version which brings in breaking API changes in iOS.

@dluksza For me that won't work as firebase_auth needs to be at least 0.15.5 for supporting MacOS.
