functionType property

@override GenericFunctionType? functionType

The type of function being defined by the alias.

If the non-function type aliases feature is enabled, a type alias may have a _type which is not a GenericFunctionTypeImpl. In that case null is returned.

Implementation

@override
GenericFunctionType? get functionType {
  var type = _type;
  return type is GenericFunctionTypeImpl ? type : null;
}

void functionType=(GenericFunctionType? functionType)

Implementation

set functionType(GenericFunctionType? functionType) {
  _type = _becomeParentOf(functionType as GenericFunctionTypeImpl?)!;
}
