I was getting this error below on an m1 Mac
1 warning generated.
ld: framework not found google_sign_in
clang: error: linker command failed with exit code 1 (use -v to see invocation)
note: Using new build system
note: Planning
note: Build preparation complete
note: Building targets in dependency order
==== Solved ====
What I had to do is go to
Xcode => Runner => Build settings => Under linking => Double click "Other linker flags"
Delete these two
-framework
"google_sign_in"
Only the framework before the "google_sign_in"
Had the same problem with image_picker also.
