instance_access_to_static_member

The static {1} '{0}' can't be accessed through an instance.

The analyzer produces this diagnostic when an access operator is used to access a static member through an instance of the class.

The following code produces this diagnostic because zero is a static field, but it's being accessed as if it were an instance field:

void f(C c) {
  c.zero;
}

class C {
  static int zero = 0;
}

Use the class to access the static member:

void f(C c) {
  C.zero;
}

class C {
  static int zero = 0;
}
