Fixes #

• Boolean-typed options (e.g. chart.polar, series.visible) are now properly typed as bool? instead of always falling back to dynamic — a latent bug in the previous generator affected every boolean-typed field across the ~4,900 generated classes (TypeScript internally represents boolean as a union of the true/false literal types, which tripped the old generator's union-handling before it ever reached its boolean check)

Changed #

• Rewrote tool/generate_options/ as a standalone Dart tool: a real tokenizer/parser for the .d.ts syntax Highcharts' type definitions use, plus a resolver reimplementing the specific pieces of TypeScript's type-checking this schema depends on (declaration merging, extends flattening, alias chasing, union collapsing). No Node.js/npm/TypeScript Compiler API needed to regenerate anymore — run dart run tool/generate_options/bin/generate.dart; see tool/generate_options/README.md for details, including the (small, enumerated) divergences from the old generator's output
• Generated classes are now grouped into ~75 files under lib/src/options/ by Highcharts option module (e.g. hc_plot_*.dart, hc_axis.dart, hc_tooltip.dart) instead of one file per class, cutting the file count from ~4,900 to ~75

Features #

• Added options, a fully typed, IDE-autocompleted alternative to the raw data string: HCOptions plus ~4,900 generated HC*Options classes (one per Highcharts option group and series type, generated against Highcharts 13), covering the full Highcharts option tree. data and options are mutually exclusive; provide exactly one
  • Generated from Highcharts' own TypeScript definitions using the real TypeScript compiler API (not hand-maintained) — run tool/generate_options/generate.sh to regenerate against whatever Highcharts currently publishes as latest; see tool/generate_options/README.md for details
  • Any dynamic-typed slot (e.g. series, whose real type is a ~100-way union of series-specific option types Dart can't model as one type) still accepts either a typed HC*Options object or a raw Map/List/primitive, so existing untyped payloads keep working unchanged, including mixed with typed options in the same tree
  • Function-typed options (formatters/callbacks) aren't represented in the typed API — Highcharts can't receive a JS function from a JSON payload either way; use data for charts that need them
  • Each generated class lives in its own hc_<snake_case_name>.dart file under lib/src/options/

Documentation #

• Corrected the README's platform support claims: Linux was listed as fully supported, but HighCharts has no real implementation on Linux (it falls through to an "Unsupported Platform" placeholder) — the linux/ native plugin is still the unmodified flutter create template stub

Features #

• Added native "save exported chart to disk" support on Android, iOS, macOS, and Windows. The plugin now intercepts the exporting module's client-side download (requires offline-exporting.js, see below) and writes the file to the platform's Downloads folder where one exists, falling back to app storage elsewhere. Adds a new dependency: path_provider (#24)
• onEvent now also reports export outcomes as {event: 'export', status: 'success'|'error', ...}

Fixes #

• Fixed asset-loading errors printing a generic "not found" message regardless of the actual failure (permission issues, corrupt bundles, etc. all looked identical); the real exception is now included
• Fixed getLocalAssetString swallowing the original exception with catch (_), making local script failures hard to diagnose

Features #

• Added globalOptions, applied via Highcharts.setOptions() before the chart is created, for settings such as lang that live outside a single chart's configuration (#29)
• Added onEvent, delivering data sent from the chart's JavaScript back to Flutter via an injected sendToFlutter(data) helper, so chart interactions (selection, click, zoom, etc.) can be handled in Dart (#25)
• Forwarded WebView JS console output (including runtime errors) to the Flutter debug console on Android/iOS/macOS, making chart configuration mistakes visible instead of silently failing in the WebView (#24)

Fixes #

• Fixed dark mode rendering title, subtitle, axis labels, legend, and tooltip text unreadably (nearly invisible against the dark background). Highcharts hard-codes light-theme colors as inline styles for these elements, which silently overrode the plugin's .highcharts-dark CSS; the plugin now re-points those inline defaults at the same dark palette via Highcharts.setOptions()
• Fixed themeMode changes at runtime not actually reloading the chart on Android/iOS/macOS/Web, so toggling an app's theme never updated an already-rendered chart
• Fixed the Web implementation not updating the chart container's theme class after its first render, since registerViewFactory only takes effect once per view
• Fixed the Windows implementation calling an undefined senthilnasa JS function and never rendering the chart at all, since Highcharts.chart(...) was registered with addScriptToExecuteOnDocumentCreated, which only applies to future navigations and never fires for the already-loaded page
• Closed the unclosed <body>/<html> tags in the Windows HTML template
• Fixed a JS evaluation error (e.g. from a malformed chart config) crashing the app with an unhandled exception instead of being caught and logged, on all platforms
• Documented that the exporting menu needs offline-exporting.js alongside exporting.js — without it, export relies on a round-trip to Highcharts' cloud server and a browser-style file download that the embedded WebView engines generally can't complete (#24)
