There is no engine selection in IOS, that's why you have this exception, it is kind of expected.

As I said above, you need to check if you are on iOS and to not call this method.

Such as:

import 'dart:io' 
...
if (Platform.isAndroid) 
{ 
      // Android-specific code, such as using setEngine 
} 
else if (Platform.isIOS) { 
     // iOS-specific code 
}
