preface
Most of the pages of your App interact with the data on the back end, which requires a network request library. Dio, like Axios for the Web front, AFNetworking for iOS (Alamofire for Swift), and Retrofit for Android, is the king of the Web request library.
That’s why we spent a lot of time on Dio. Mastering Dio allows us to speed up the interface to the back end! This article makes some summary of the previous chapter, also can facilitate you to find the corresponding chapter.
