Type mismatch and return type error

[ketulrastogi]

(day, month, year) {
DateTime _birthdate = DateTime.utc(year, month, day);
print('generated date time $_birthdate');
}

This function has a return type of 'String', but doesn't end with a return statement.
Try adding a return statement, or changing the return type to 'void'.dart(missing_return)

The argument type 'String Function(int, int, int)' can't be assigned to the parameter type 'String Function(int, int, int, bool)'.dart(argument_type_not_assignable)

I'm also facing the same issue, do you have working code regarding this?

You put a variable name for bool in the parameter and return null.

Here's the working code.

(day, month, year, potato) {
                                    DateTime dateTime = DateTime.utc(year, month, day);
                                    print('generated date time $dateTime');
                                    return null;
                                  }
