When i try to build in Flutter for iOS.. I am getting the error as follows:
```
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require':
dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.4/lib/ffi_c.bundle, 9): no suitable image
found. Did find: (LoadError)´´´
Could you suggest me how can I overcome this error?
