Aurum · Sell
Aurum · Sell is a production-ready Web3 Flutter screen from FlutterKit Pro, installable with flutterkit add web3-trade-simple-sell.
The Sell screen lets a holder convert crypto back to fiat from a single, focused panel. A Buy/Sell segmented pill sits in the dark AppBar with the Sell side outlined in a red (#F6465D) sell accent. The hero is a FittedBox-scaled "0 BTC" headline at 48px using Inter with FontFeature.tabularFigures() so digits never jitter as you type, with a live "~ $0.00" fiat estimate beneath it computed from a fixed BTC rate. A balance line reads "Available 0.184213 BTC" beside a brand-yellow "Max" pill that one-taps the full holding into the field; entering more than the balance flips the amount and label red and disables the action. A tappable Bitcoin selector chip carries a painted BTC ticker badge (no network image, no glyphs) and a chevron. A 3x4 painted numpad built from a GridView with InkWell keys (digits, decimal guard, backspace) drives all input, and a full-width red "Review sell" FilledButton enables only when the amount is valid. Pure Flutter, forced dark ThemeData, bundled Inter font; onBack, onToggleBuy, onSelectCoin and onReview callbacks keep it backend-agnostic.
