  • Made compatible with flutter


  • Switched to Dart 2
  • Switched from dartson (reflection) to built_values for JSON serialization

  • Every endpoint returns a DataResponse now and this DataResponse contains meta from the http request and deserialized data
  • APIResponse is now fully serializable.

  • Made every endpoint call an explicit async

import 'dart:async';
import 'dart:io';
import 'package:uwdart/uwdart_io.dart';

Future main() async {
  String apiKey = await new File('key.txt').readAsString();

  // Create the client
  UWDart uwClient = new UWDart(apiKey);

  // create raw requests
  uwClient.makeRawRequest('courses/CS/245').then((data) {

  final courses = await uwClient.course.getAllCourses();

  // The request to the api returns meta data which can be used by the user

  // For actual endpoint data, get it using data getter
  final courseData = courses.data;


  for (int i = 0; i < 50; i++) {
    String catalogNum = courseData[i].catalogNumber;
    String subject = courseData[i].subject;

    final courseSubject = await uwClient.course.getCourseBySubjectCatalog(subject, catalogNum);

    print('Course Name: ${courseData[i].title}');
    print('Course Subject: ${courseData[i].subject}');
    print('Course Catalog: ${courseData[i].catalogNumber}');
    print('Course ID: ${courseSubject.data.courseId}');
    print('Course Url: ${courseSubject.data.url}');

  final news = await uwClient.news.getNews();

  for (final article in news.data) {
    String articleTitle = article.title;
    int articleID = article.id;
    String articleSite = article.site;
