This time we cannot throw and catch C++ exceptions in plugin platform code. Because Flutter statically links libcxx and libcxxabi which exposes symbols like __cxa_decrement_exception_refcount, which will introduce two versions of cxxabi functions, throwing libcxx exceptions, and catching them by libstdc++ method.
To fix this problem, this PR set
__LIBCXXABI_DISABLE_VISIBILITY_ANNOTATIONSto suppress symbol leaks, which is tested and worked correctly. All platforms artifacts will get benefit from this pr.This pull request fixes issue flutter/flutter#66575 and flutter/flutter#74599.
