ZHKLine Flutter

A Flutter candlestick chart and financial chart library for K-line charts, technical indicators, trading chart interactions, OHLCV data, and cumulative depth charts. It uses CustomPainter and delegate-based rendering, so you can start with the default UI and replace drawing, layout, overlays, or data adapters only where your app needs custom behavior.

Chinese documentation is available in README_CHINESE.md. For custom UI, depth chart integration, external controls, realtime data, and complete examples, see example/use_docs.md.
