My work, Atomic.io, has a Flutter SDK - which I am the product owner of. I made this demo app to showcase our Flutter SDK.
First demo app for Atomic.io
In the app root directory, remember to create a .env file with the following set:
API_KEY=''
API_URL=''
USER_ID=''
Also, remember to place the generated jwtRS512.key file in an assets folder in the app root directory like this: assets/jwtRS512.key
