Aurum · Fear & Greed
Aurum · Fear & Greed is a production-ready Web3 Flutter screen from FlutterKit Pro, installable with flutterkit add web3-markets-fear-greed.
Aurum's Fear & Greed screen turns one number into a market-sentiment dashboard. The hero is a rounded dark card holding a CustomPainter semicircle gauge: a graduated red-to-amber-to-green SweepGradient arc with tick marks every 10%, a triangular white needle with a hub, and a big tabular-figure value (72) plus its classification ("Greed") tinted by zone. "Extreme Fear" and "Extreme Greed" anchor the two ends. Below, a "Recent values" card lays out four CustomPaint mini-bars (Now, Yesterday, Last week, Last month) — each a rounded track with a colour-coded fill scaled to its 0–100 reading — followed by a muted explainer card describing how volatility, momentum, volume, social sentiment and dominance combine. Built pure Flutter (Flutter SDK + dart: only): two custom painters (_GaugePainter and _HistBarPainter) draw all graphics, with no images or icon glyphs. A forced dark theme, bundled Inter font, ListView layout and a single onBack VoidCallback keep it backend-agnostic — feed it any index value and history list to drive the gauge and bars.
