unnecessary_type_name_in_constructor

Unnecessary type name in a constructor.

The analyzer produces this diagnostic when an in-body constructor declaration includes a type name.

The following code produces this diagnostic because the generative constructor declaration includes the type name:

class C {
  C();
}

The following code produces this diagnostic because the factory constructor declaration includes the type name:

class C {
  factory C() => C._();
​
  new _();
}

Remove the type name from the constructor. If the constructor is named, also remove the period before the name:

class C {
  new();
}

or

class C {
  factory() => C._();
​
  new _();
}
