Access of static class method by static generic method

   January 7, 2021  2 Comments on Access of static class method by static generic method

I try call static method of class by generic method and it’s not compiling with error:
Error: The method 'foo' isn't defined for the class 'dart.core::Type'

https://dartpad.dartlang.org/a94baf3ef84a6b22827a39aa4c5133b8

class A {
  static void foo() {
    print('I <3 ');
  }
}

class B {
  static void bar<T extends A>() {
    T.foo();
    print('Dart');
  }
}

void main() {
   B.bar<A>();
}

PS: I doesn’t know, it’s an issue, bug or only question, but I would be glad if it was possible

And it’s normally work in Java! 
public class A {
  public static void foo() {
    System.out.print("I <3 ");
  }
}

public class B {
  public static <T extends A> void bar() {
    T.foo();
    System.out.print("Java");
  }
}

public class Main {
  public static void main(String[] args) {
     B.<A>bar();
  }
}

  2. @eernstg Thank you very much for your research and detailed answer. I agree, perhaps in real-world problems call static methods by this way really not needed

    By the way, I tried DLang and your example works fine in this lang (unlike Java)

    import std.stdio;

class A {
    static foo() {
    	writeln("A.foo");
    }
}

class A2 : A {
    static foo() {
    	writeln("A2.foo");
    }
}

class B {
    static foobar(T : A)() {
        T.foo();
    }
}

void main() {
    B.foobar!A();
    B.foobar!A2();
}
