If not, sometimes ENOENT isn’t referring to the file you’re trying to execute. For example, it may be referring to the loader if this is a 32-bit executable and you didn’t enable the i386 compat extension in your flatpak.
It’s also possible that the API you’re using doesn’t expect to get a command line string, so it’s trying to execute a file called qrcp -i wlo1 receive. There’s probably a better venue for that discussion though; I don’t think Flutter is particularly relevant to GNOME.
