Aurum · Sign Request
Aurum · Sign Request is a production-ready Web3 Flutter screen from FlutterKit Pro, installable with flutterkit add web3-sign-request.
A wallet-style signature-request sheet for the Aurum Web3 crypto wallet, shown as a dark bottom sheet over a dimmed, tap-to-dismiss scrim. A grab handle sits above a centered "Signature request" title and an "app.uniswap.org wants you to sign" origin line. A "Message" label heads a rounded raw-data panel that prints the exact EIP-712 permit body — Permit: UniSwap V4, spender address, token: USDC, value, nonce and deadline — at 1.5 line height so long hex wraps cleanly. Below it a bordered row pairs a gas-pump icon and "Estimated gas" with a green "Free (off-chain)" value, then an amber-tinted warning card (warning icon + "This permit lets the spender move your USDC. Only sign for sites you trust.") makes the approval risk explicit. A two-button footer offers an outlined Reject and a gold filled Sign. Built in pure Flutter: a Stack with a Positioned.fill GestureDetector scrim, an Align bottom sheet, Material3 dark Theme, bundled Inter font, Material icons only (no images), and onSign / onReject VoidCallback hooks so it stays fully backend-agnostic.
