conflicting_constructor_and_static_member

'{0}' can't be used to name both a constructor and a static field in this class.

'{0}' can't be used to name both a constructor and a static getter in this class.

'{0}' can't be used to name both a constructor and a static method in this class.

'{0}' can't be used to name both a constructor and a static setter in this class.

The analyzer produces this diagnostic when a named constructor and either a static method or static field have the same name. Both are accessed using the name of the class, so having the same name makes the reference ambiguous.

The following code produces this diagnostic because the static field foo and the named constructor foo have the same name:

class C {
  C.foo();
  static int foo = 0;
}

The following code produces this diagnostic because the static method foo and the named constructor foo have the same name:

class C {
  C.foo();
  static void foo() {}
}

Rename either the member or the constructor.
