createdMessage static method
Pure — the raw-key display plus the revoke hint, so the printed
prefix and the printed revoke command can't drift apart without a
test catching it. Takes the server's own prefix (already in the
create response) rather than re-deriving it from rawKey.
Implementation
static String createdMessage({
required String rawKey,
required String prefix,
}) =>
'\n'
' $rawKey\n'
'\n'
' Prefix $prefix — how it appears in `keys list`,\n'
' and how to revoke it:\n'
' appflight keys revoke $prefix';
