   pickFirst 'lib/armeabi-v7a/libcrypto.so'
   pickFirst 'lib/armeabi-v7a/libssl.so'
   
   pickFirst 'lib/x86/libcrypto.so'
   pickFirst 'lib/x86/libssl.so'
   
   pickFirst 'lib/x86_64/libcrypto.so'
   pickFirst 'lib/x86_64/libssl.so'
   
}

2.Setup iOS #

    }on PlatformException{}
    if (!mounted) return;
  }

Error: String
