Override method in dart on fly (like JAVA)

Question

Is there way to overriding method in Dart like JAVA, for example:

public class A {
    public void handleLoad() {
    }
}

And when overriding:

A a = new A() {
    @Override
    public void handleLoad() {
        // do some code
    }
};

Answer 1

No, Dart does not have anonymous classes. You have to create a class that extends A and instantiate it.
