use built in types as dto names & import dart:io

[dickermoshe]

We need to add

double
int
num
bool
null
dynamic
void

to reserved words

Also dart:io wasnt imported only for dart mappable

// coverage:ignore-file
// GENERATED CODE - DO NOT MODIFY BY HAND
// ignore_for_file: type=lint, unused_import

import 'package:dart_mappable/dart_mappable.dart';
