extension_conflicting_static_and_instance

An extension can't define static member '{0}' and an instance member with the same name.

The analyzer produces this diagnostic when an extension declaration contains both an instance member and a static member that have the same name. The instance member and the static member can't have the same name because it's unclear which member is being referenced by an unqualified use of the name within the body of the extension.

The following code produces this diagnostic because the name a is being used for two different members:

extension E on Object {
  int get a => 0;
  static int a() => 0;
}

Rename or remove one of the members:

extension E on Object {
  int get a => 0;
  static int b() => 0;
}
