Aurum · Lock Screen
Aurum · Lock Screen is a production-ready Web3 Flutter screen from FlutterKit Pro, installable with flutterkit add web3-auth-lock.
The Aurum Lock Screen is the re-entry gate for a dark crypto wallet, rendered on a near-black 0xFF0B0E11 canvas. A 64px CustomPaint logo draws a gold-gradient hexagon with a stencilled "A" mark, under a bold "Enter passcode" heading and the muted "Unlock Aurum to continue" subline. Six circular passcode dots sit centered: empty dots use a hairline ring, filled ones fill solid gold (0xFFF0B90B). A self-painted numpad lays out 1-9, 0, a Face ID key (face_retouching_natural icon, gold) and a backspace key as InkWell circles inside Expanded rows, so it scales fluidly without fixed pixel math. Tapping six correct digits fires onUnlocked via a post-frame callback; a wrong sequence flips the dots red (0xFFF6465D), runs a 420ms sine-wave shake through an AnimationController plus Transform.translate, shows "Wrong passcode. Try again." then clears the code. A gold "Forgot passcode?" TextButton pins the bottom. Pure Flutter, bundled Inter font, forced dark Theme, fully backend-agnostic via onUnlocked, onBiometric, onForgot and a configurable expectedCode.
