Obiously the outbreak of coronavirus is a big deal, and the main motivation for this project, but there some other stuff too.

This project is part of my first time participating in a Hackathon. With the prompt of "helping the community", that is the big picture goal for this project.

In order to build this app, I have had to teach myself a few new things. Here's a list, with links for refrence:

• Dart
• Flutter
• Google Cloud (for maps api)
• Firebase (for remote config with api keys)
• SQLite
• Asynchronous Programming

• Contact Tracing as a concept
• Google and Apple's announcement of a partnership on a bluetooth contact tracing protocol
• A similar system created by MIT
• SafePaths app, led by MIT, with using a path-crossing algorithm to detect if people have "crossed paths"
