COVID-19 Stopper

• 

  The red marker indicate the encounter with known COVID-19 patient

Inspiration

I was inspired by how big tech companies keeps spying on people location for their own good. The idea of creating a database of COVID-19 patient before they are confirmed came to mind easily.

What it does

An app that warns you of potential past contact with confirmed COVID-19 patients. It tracks your location data and save it locally on your phone (ios / andriod), and it compares the data from the server to see if the user have encountered COVID-19 patients in the past.

How I built it

I built it with Flutter as the mobile framework and firebase as the backend.

Challenges I ran into

I built this app in less than 15 hours. So I got to solve many things quickly in order to finish it in time. The part that I spent most of my time on is connecting the flutter app to the firebase backend. Writing to the database kept crashing the app.

Accomplishments that I'm proud of

I finished the app in time and the UI looks fine.

What I learned

I learned more techniques of building apps in flutter. Got to explored different packages and widgets that I haven't used before

What's next for COVID-19 Stopper

Polish the app and publish to App Store and Google Play Store? At lease I hope so, since I really want to create something that's not just a hackathon project.
