Yes, nostr:npub1gp4xzpmluelsakjtayc4wtzj97fhj5kakqjvsannu00xkdlf4x8s0xdqyq used some initial code from nostrmo.
But signature verification in nostrmo is turned off because bip340 dart lib is too slow.
I had to use native android channel and use acinq lib in order to be usable.
Main dev says he has no time anymore to develop it.
