Krzysztof kuhy Rudnicki 2298fd4ba2 Own the Google sign-in glue, on desktop as well as Android ... Five apps had copied google_sign_in_backend.dart; home_inventory's copy was byte-identical to todo's. lyricanki was about to become the sixth, which is the mistake this package exists to prevent. So the plugin call moves here. Desktop is the new half. google_sign_in ships android, ios and web implementations only -- there is no google_sign_in_linux -- so lyricanki's real GTK build could never have used the plugin, and "one tap" would have meant "one tap on the phone, type a password on the PC". The OAuth loopback flow covers it: bind a socket, open the system browser, catch the redirect, exchange the code with PKCE. Both halves return a Google ID token of the same shape, so signInWithGoogle cannot tell them apart. googleSignInSupported takes the client id rather than reading a const. In todo the emptiness check was a second conjunct at the call site, and moving the fetcher here without it would have let a forgetful app ship a button that always reports "cancelled" -- todo's own file documents that failure. Taking the value as an argument makes the check impossible to drop. The decision (which flow, or none) is pure and covered; the two one-line delegations that reach a platform channel and a real browser are the only suppressions. 83 tests, 100% coverage.
