Flutter build ios bitcode problem, how to fix bitcode error

Question

i try to build ios with my phone connected or flutter build ios i got this error

ld: '/Users/Library/Developer/Xcode/DerivedData/Runner-dwvxvkkosgpgqncynmszqlholtde/Build/Products/Debug-iphoneos/BoringSSL-GRPC/libBoringSSL-GRPC.a(BoringSSL-GRPC-dummy.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/Library/Developer/Xcode/DerivedData/Runner-dwvxvkkosgpgqncynmszqlholtde/Build/Products/Debug-iphoneos/BoringSSL-GRPC/libBoringSSL-GRPC.a' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I had a similar problem after installing one library which was dependent on the bitcode. Please change Enable Bitcode to all of the targets on the project Pods like in the image,
