I wrote some glue code (https://pub.dev/packages/amberflutter) to be able to easily use https://github.com/greenart7c3/Amber from Flutter. I hope someone can try it out and give any input!

Here is a demo of getting my pubkey from Amber, and I also took the opportunity to use nostr:npub1r0rs5q2gk0e3dk3nlc7gnu378ec6cnlenqp8a3cjhyzu6f8k5sgs4sq9ac design for the profile page to revive my flutter "skills" 🤣
