Release v2.0.0 · brandtnewlabs/react-native-livechart

First major release. Highlights: a new metrics design-token prop, a uniform
feature-flag API, and a scrub-performance fix.

npm install react-native-livechart@2.0.0

⚠️ Breaking changes — migrating from 1.x

LiveChartSeries now scrubs by default. scrub defaulted to false; it now
defaults to true, matching LiveChart. Pass scrub={false} to restore the
old behavior. (Legend taps are unaffected — chips sit outside the scrub gesture.)
DotConfig.show is deprecated in favor of dot={false} to hide the live
dot. dot={{ show: false }} still works and is equivalent — no rush to migrate.
Every overlay toggle now follows the same boolean | Config convention
(badge, gradient, pulse, valueLine, scrub, yAxis, xAxis,
leftEdgeFade, legend, and now dot). This is additive for everything except
the two items above.

See the Migrating to v2 section in the README.

metrics prop on both charts — sizing & motion design tokens, the
geometry/feel analogue of palette. Namespaced (badge, candle, grid,
motion, emptyState) with per-key overrides, exposing previously-hardcoded
constants (badge pill geometry, candle body bounds, grid/axis fade and lerp
speeds, empty-state layout). New types: LiveChartMetrics,
LiveChartMetricsOverride, and the five namespace interfaces.
dot accepts a boolean on both charts (dot={false} to hide).

Crosshair overlays no longer emit React's "final argument changed size between
renders" error while scrubbing (a React Compiler × Reanimated auto-dependency
interaction; the affected useDerivedValues now use explicit deps).

The line is decimated to ~2 points per horizontal pixel (min/max per pixel
column — envelope and volatility spikes preserved). Dense or wide time windows no
longer make per-frame work scale with sample count, fixing the sustained-scrub
frame drops on saturated windows. Sparse windows are unchanged.
