Web version of Billy

[lyqht]

A few possible technical approachs:

1. react-native-web
   • However, many devs have raised concerns about navigation when adding react-native-web into any RN project.
2. Use Solito

Other notes

• React-navigation-tabs should not be used in the web version. So we need rethink the UI of this.
• We could possibly try swapping out for React Native URL router, a new library that seems to support RN Web

Might rebuild Billy as a web app using Solito instead!
