super_in_redirecting_constructor

The redirecting constructor can't have a 'super' initializer.

The analyzer produces this diagnostic when a constructor that redirects to another constructor also attempts to invoke a constructor from the superclass. The superclass constructor will be invoked when the constructor that the redirecting constructor is redirected to is invoked.

The following code produces this diagnostic because the constructor C.a both redirects to C.b and invokes a constructor from the superclass:

class C {
  C.a() : this.b(), super();
  C.b();
}

Remove the invocation of the super constructor:

class C {
  C.a() : this.b();
  C.b();
}
