Method Overriding in Dart when the Return Type is "void"

I anticipated a compile-time error when overriding a method in Dart without the correct (to my knowledge so far) return type. However, things seem to be different when the return type of the method is void:

abstract class AbstractClass {    void methodDoesNotReallyReturnVoid();  }    class ConcreteClass extends AbstractClass {    // NO ERROR here!    @override    int methodDoesNotReallyReturnVoid() => 12;  }    void main() {    print(ConcreteClass().methodDoesNotReallyReturnVoid()); // hm...?  }    

The code above compiles without complaints and prints the integer as expected though I did not properly override that method like, for example, in Java.

May I know what is distinct about "void" here?
