fincharts 0.2.0

A Flutter-native financial charting engine for fintech, trading, and investment applications.

Changelog

0.2.0

Added

• Live data support: FinancialChart is now explicitly designed and documented for streaming/frequently-updating data (tick updates to the forming candle, and new candles appended as bars close), preserving the viewport's "scrolled to latest" state and an active crosshair across updates.
• FinancialChartConfig.showLivePriceLine — a dashed reference line and price tag at the latest close, colored by direction, anchored to the last candle in the full data set regardless of the current viewport.
• Mouse-wheel / trackpad-scroll zoom, as the primary desktop/web zoom path.
