I have published my androd app OZBargain deals in playstore. This app displays latest deals from OZBargain AU with faster navigation and loading using customised rest api.
This app developed using Google Flutter and Visual Studio code.
The rest api is deployed on Google cloud using app engine and uses Google firestore as backend. Also uses Google cloud schedular, cloud functions, etc.
