Overview

Clone the app and open on your IDE. The IDE will probably prompt you to install all sorts of dependencies and libraries.

Basics

This app has three core functionalities:

Make an API call

The JSON file is hosted on this repo, raw.githubusercontent.com/jiebo/dcube_flutter/master/assets/dcube_projects.json. After calling, the JSON is parsed into a list of Project objects.
Display a list

With the list, the app can then display the individual items. Currently there's only an image and a title. If you want to add more meta data in please feel free.
Navigate between screens

The onTap() function of the list item triggers navigation to the ProjectDetailsScreen, which displays the description.

This is an OR clause, so just pick the one you like.

UI - Just fancy up the app however you want, look through libraries or samples out there
API - Consume the Google PlayStore or Apple AppStore APIs and display app-related information
