dot_shorthand_undefined_member

The static getter '{0}' isn't defined for the context type '{1}'.

The static method or constructor '{0}' isn't defined for the context type '{1}'.

The analyzer produces this diagnostic when a dot shorthand is used to reference a member, but that member doesn't exist.

The following code produces this diagnostic because the enum E doesn't define a static member named c:

void f() {
  E e = .c;
  print(e);
}

enum E {a, b}

If the name is correct, then define a member with that name in the context type, which in this case is the enum E:

void f() {
  E e = .c;
  print(e);
}

enum E {a, b, c}

If the name is not correct, then replace the name with the name of an existing member from the context type, which in this case is the enum E:

void f() {
  E e = .b;
  print(e);
}

enum E {a, b}
