This DEMO application shows the products with best prices from the store. Also you could find store details and map.
For this project I used Firebase to get all data about products and store details. I got familiar with StreamBuilder which is great widget to get and present data from the snapshots. Here I used external libraries like intl to support mulit-languages feature and json_serializable to quickly serialize JSON to objects. Also I created unit and widget tests (for one function and widget), just to check how to implement tests for Flutter application.
