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.
