kline_flutter 0.5.0

A Flutter candlestick and K-line financial chart library with technical indicators, OHLCV trading charts, depth charts, and customizable delegates.

Changelog

0.5.0

• Reorganized package and example tests to mirror the source directory structure.
• Pruned low-value and duplicate tests while keeping focused regression coverage for core chart behavior.
• Added regression coverage for controller-driven K-line scroll requests and default delegate secondary pane height fallback.
• Added Chinese testing documentation that clarifies unit, widget, and integration test boundaries.

0.4.0

• Switched the default README to English for pub.dev and GitHub discovery.
• Moved the original Chinese README to README_CHINESE.md.
• Updated package metadata with an English description focused on Flutter candlestick charts, K-line charts, financial charts, technical indicators, OHLCV trading charts, and depth charts.
• Translated the changelog to English to improve pub.dev package scoring.

0.3.1

• Updated package documentation.

0.3.0

• Breaking change: replaced the default indicator enum API with dynamic indicator definitions based on KLineIndicatorSpec<T> and KLineIndicatorSeries<T>.
• Added KLineWidget.mainIndicators and secondaryIndicators; the indicator selector now uses the provided lists as the single source of truth. Omitted lists use defaults, and empty lists hide the corresponding indicators.
• Changed KLineDataAdapter.indicatorValue to accept String valueId, so apps can support arbitrary custom indicator values.
• Added KLineDefaultIndicators constants and factories for built-in MA, EMA, BOLL, VOL, MACD, KDJ, RSI, and WR indicators.
• Added custom sub-chart indicator support. Simple series indicators are drawn automatically, while complex indicators can provide a custom renderer through KLineIndicatorSpec.renderer.
• Improved default placeholder height and viewport height calculation by using delegate-provided heights consistently.
• Fixed occasional blank space or flicker on the right side when old scroll offsets exceeded the new content width after zooming out, and extracted ScaleGestureHandler for scale gesture logic.
• Updated the example custom indicator page to demonstrate default VOL, CCI line indicators, and a custom bar renderer together.

0.2.0

• Added realtime controls to KLineController: follow latest, scroll to latest, scroll to index, and reveal the selected item.
• Added a realtime update example page showing how business code updates data first and then calls the controller to scroll to the target position.
• Improved K-line scroll boundary synchronization and fixed edge cases where loading more data did not trigger near the end or caused viewport drift.
• Fixed the example K-line cache window so refreshing 50 rows is not polluted by previously loaded-more in-memory data.
• Adjusted the realtime demo timer so simulated pushes only run when follow latest is enabled.
• Replaced the hard-coded default indicator switcher height with layout config.
• Added realtime data integration docs clarifying that the package does not decide where incoming data should be inserted.
• Updated publish ignore rules so build/ artifacts are not included in the pub package.

0.1.2

• Changed .fvmrc to the current FVM-compatible JSON format, fixing fvm flutter and make gen under example.
• Synced the local path dependency version in example/pubspec.lock to 0.1.1.

0.1.1

• Renamed the package to kline_flutter and updated the public entrypoint and example imports.
• Completed publish configuration with LICENSE, .pubignore, and required publish validation files.
• Improved the first README screen, quick-start instructions, and core value proposition copy.
• Switched README preview images to GitHub raw URLs to keep image assets out of the pub package.
• Reduced custom UI image display width in the README for better readability.

0.1.0

• Initial release of the Flutter K-line chart component.
• Added quick integration through KLineWidget and deep custom drawing through KLineChartDelegate.
• Added default MA, EMA, BOLL, MACD, KDJ, RSI, WR, and VOL indicators.
• Added DeepChart for cumulative bid and ask depth charts.
• Added examples, detailed usage docs, and custom UI samples.
