Aurum · Buy
Aurum · Buy is a production-ready Web3 Flutter screen from FlutterKit Pro, installable with flutterkit add web3-trade-simple-buy.
The Buy tab of the Aurum exchange shell opens on a centered Buy/Sell segmented toggle, then a huge tabular-figure "$0" amount with a live "~ 0.000000 BTC" conversion line beneath. Three rounded preset pills ($50, $100, $500) one-tap the amount, and a tappable coin card shows a painted BTC ticker badge, "Bitcoin", and a green "$64,120.42 · +2.41%" quote. Entry runs through a fully custom 3-column numpad (digits, decimal, backspace icon) — no system keyboard — enforcing two decimal places and a nine-digit cap. A brand-yellow "Review buy" bar is pinned at the bottom and enables only once the amount exceeds zero, above a five-item nav (Home, Markets, Trade, Earn, Profile) with Trade active. Built in pure Flutter on a forced dark Binance-style theme with the bundled Inter font; the BTC badge and quote are drawn with widgets (no glyph fonts, no network images). Fiat-to-crypto math runs live in state from a const rate, and every action is a callback (onTabSelected, onSelectCoin, onReview, onToggleSell), keeping it backend-agnostic and drop-in.
