flutter_chen_kchart changelog

4.7.1 #

Improved: Refined the example trading UI, settings layout, period toolbar, and responsive light/dark presentation.
Added: Example intervals for 1m, 5m, 30m, and 1w, plus a return-to-latest shortcut after browsing history.
Fixed: Trend-angle labels no longer render a light background block in dark themes.

4.7.0 #

Improved: MA, BOLL, volume MA, and OBV MA now use resumable rolling-window calculations with safer indicator parameter normalization.
Fixed: BOLL/OBV/CCI calculation state, realtime gap repair and merge priority, and concurrent or disposed programmatic scale animations.
Fixed: Invalid marker sizes and numeric values, signed compact formatting, indicator-series visibility, BOLL labels, and missing timestamp display.

4.6.0 #

Added: Bounded drawing undo/redo, transaction merging, persistence validation, and controller history APIs.
Improved: OHLC magnet snapping, editable endpoints, extended-line/ray geometry, viewport culling, and time-stable anchors across data updates.
Fixed: Unselected drawings no longer intercept chart panning; selection handles, clipping, offscreen labels, edit cancellation, and malformed legacy drawings are handled correctly.

4.5.0 #

Added: Incremental custom-indicator calculation, configurable price ticks/time zone, and explicit depth-data revision support.
Improved: Realtime K-line, data-quality, marker, chart, depth, and drawing performance for large datasets.
Fixed: Percentage/log axes, late realtime indicator updates, interval viewport reset, invalid market data, empty panes, amend confirmation, terminal-order dragging, and dense markers.
Changed: Example trade-history visibility moved to Settings, and the symbol selector was removed.

4.4.0 #

Added: Trading overlays for entry/liquidation prices, unrealized PnL, order status, grouped TP/SL lines, and independent visibility controls.
Added: Async price amendment confirmation through onTradingLineDragConfirm; terminal orders are non-draggable by default.
Improved: Large trade-history performance with time -> index, visible-range, and LRU text-layout caches, plus explicit cache revision APIs.
Improved: Example trading overlays now use current K-line data and include trade-history controls, amend confirmation, and a 20,000-marker benchmark.

4.3.0 #

Added: tradeMarkers for passing external buy/sell order data and rendering B/S badge markers inside the chart.

4.2.0 #

Added: Date-jump support that can request the target history page before scrolling to the selected time.

4.1.0 #

Added: Extended built-in indicator coverage with EMA, SAR, OBV, StochRSI, multi-period RSI, and multi-period WR.
Added: Indicator configs can now override per-series colors and hide individual indicator series.
Added: Example indicator settings panel for editing built-in indicator parameters, colors, and visible series.
Improved: Indicator values now recalculate when indicatorConfigs or maDayList change, including configurable volume moving-average periods.

4.0.0 #

Added: Data-source mode for library-managed historical loading, left-swipe pagination, realtime updates, cancellation, caching, reconnects, and data quality reporting.
Added: Controller APIs for reload, manual history loading, latest-edge follow, visible/logical ranges, time/index jumps, fit content, coordinate conversion, and crosshair control.
Added: Time and price axis features including manual price ranges, price-axis dragging, percentage mode, and logarithmic mode.
Added: Multi-pane and indicator APIs with weighted pane layouts, configurable built-in indicator parameters, custom indicator registration, and custom series rendering.
Added: Trading overlay APIs for order lines, position lines, trade markers, draggable take-profit/stop-loss lines, and line/marker tap callbacks.
Improved: Realtime and historical data handling with gap repair, incremental indicator recalculation, safer cache isolation, and faster ordered bar lookup/merge paths.
Improved: Rendering performance across chart painting, visible-range callbacks, trading overlays, drawing tools, text styles, candles, volume, and custom indicator rendering.
Changed: Example K-line view now uses the data-source protocol for mock/live data, symbol switching, left-swipe pagination, realtime updates, and trading overlay demos.

3.4.0 #

Fixed: Example release APK now declares INTERNET permission so live-market data works after installation.
Fixed: Example live-market history loading now uses OKX historical candles for older intraday data and keeps falling back across providers when a source returns empty results.
Fixed: Example chart load-more requests now page from an earlier time boundary and filter duplicate rows so left-swipe history loading can continue reliably.
Added: Example app symbol selector for quickly switching between multiple trading pairs.

3.3.0 #

Added: ChartStyle.candleBodyMode and CandleBodyMode.solid/hollow for switching between solid and hollow candlesticks.

3.2.0 #

Added: Color-blind-friendly palette support via ChartColorVisionMode and ChartThemeManager.

3.1.0 #

Fixed: Safe handling for empty data and corrected the first valid BOLL window.

Fixed: Controller reattachment when KChartWidget rebuilds with a new KChartController.
Fixed: Drawing tool extended index conversion and KDJ overlay text conditions.
Improved: Grid rendering loops, painter repaint checks, and high-frequency drawing allocations.
Improved: Drawing tools now receive the real main-chart rect instead of duplicating hard-coded bounds.
Improved: Added usable baseline implementations for several drawing tool hitTest, getBounds, and move paths.
