Ah, I love rustdesk. I didn't know it was Flutter based. Only minor complaint about Rustdesk is that when you send the official link to people, they are frightened by a big scary "Scammer" alert[1]. To you and me, we immediately understand its actual purpose, but to non technical folks they hesitate to click it. I've seen this too many times.
