Client Application

Overview​

The client application (labelled CHITTI. on market stores) is the entry point for customers who are currently enrolled (or) wish to be enrolled customers of CHITTI. to access the resources purchased (or) to be purchased.

The application allows users to sign in with their organizational learning management system credentials as a measure of secure authentication to provide a personally tailored experience. The users are then offered to purchase content for the subjects they wish to pursue, of which they are enrolled in the current semester in the organization. On successful purchase, the content is available to the users, which is revoked upon completion of the exam automatically.

NOTE: The client application provides a free-tier for the users, i.e, the first unit of every subject is provided as a freemium offerring.

The client application is available to the public for the following platforms:

Technology Stack​

  1. Flutter 1

Architecture​

Assuming the usage of the client application to be high and predicting the behaviour of application users, we identify a heavy requirement for well-architected modelling to handle the high surge in data and request to the server. Thus the application makes well use of the clean architectural principles and components which will be discussed in the next page.

Setup​

The entry point to the code is available at lib/main.dart.
