js_widget_runtime 0.4.6

Run JavaScript widgets as Flutter widgets using QuickJS (VM) or Web Workers (web).

0.4.6

• Add transition animation nodes to the JSON renderer. entrance plays a one-shot mount animation (animation: fade, slideUp, slideDown, slideLeft, slideRight, scale, fadeScale; delay ms for staggered list entrances, duration, curve) — implemented over TweenAnimationBuilder with an Interval curve, so no timers are ever scheduled. animatedSwitcher wraps Flutter's AnimatedSwitcher: when switchKey changes between renders the old child animates out and the new one in (animation: fade, slideLeft, slideRight, slideUp, scale, fadeScale), keyed via ValueKey(switchKey). Both follow the renderer's input tolerance: unknown variants fall back to fade, numeric strings parse, garbage never crashes. The curve parser is now shared as jsCurve in js_node_helpers.dart.

0.4.5

• Add a map node to the JSON renderer, built on flutter_map + latlong2 with OpenStreetMap tiles (no API key). Props: center {lat, lng}, zoom, markers [{id, lat, lng, label?, color?}], polylines [{points, color?, width?}], and fitBounds (true to fit all markers/polylines, or an explicit [[lat, lng], [lat, lng]] corner list). Events route through the standard bridge: onTap fires with {lat, lng} and onMarkerTap with {id}. JsonWidgetRenderer.mapTileProvider lets hosts/tests inject a custom TileProvider so tile loading never has to hit the network.

0.4.4

• Automated patch bump.

0.4.3

• Renderer no longer crashes on malformed numeric props from generated widgets: jsDouble/jsDoubleOrNull now parse numeric strings, take the first numeric element of a list, and fall back instead of throwing a cast error (e.g. borderRadius: [14, 14, 0, 0] previously killed the whole render tree). borderRadius in decorations, cards, inkWell and clipRRect also accepts CSS-style corner lists ([all], [tl-br, tr-bl], [tl, tr-bl, br], [tl, tr, br, bl]) via the new jsBorderRadius.

0.4.2

• Fix web compilation of JsWidgetEngine: _defaultBackend referenced FlutterJsWidgetEngineBackend unconditionally, but the conditional import resolves to the Web Worker backend on the web, so any web build importing the wrapper failed with "Method not found: 'FlutterJsWidgetEngineBackend'". The platform pick now lives in a factory behind its own conditional import (js_widget_engine_default.dart / js_widget_engine_default_web.dart).

0.4.1

• Fix JsWidgetBridge.callEvent for rapid-fire gestures: concurrent events (tap-down / tap-up / tap) raced on a single completer, so a stale __jsr_event_done completed the next event early and the following callEvent crashed with "Future already completed", permanently wedging event delivery (dead buttons in gesture-heavy widgets). Events are now serialized through an internal queue, and __jsr_event_done handling is take-and-null so stray/duplicate dones are ignored.

0.4.0

• Add pluggable JS engine backend:
  • New JsWidgetEngineBackend interface.
  • JsRuntimeConfig.backend lets hosts use a custom engine (e.g. QuickJS FFI).
  • Default backends remain flutter_js on VM and Web Worker on web.
• Add host-provided media support for video/audio nodes:
  • JsMediaHost, JsVideoController, JsAudioController interfaces.
  • JsonWidgetRenderer.mediaHost wires real players while the core package stays free of heavy native media dependencies.
• Add ExternalAssetResolver and JsonWidgetRenderer.externalAssetResolver for external:<id> image sources.
• Add dynamic font loading via JsFontResolver, JsFontLoader, and the fontFamily text style prop.

0.3.2

• Export UiViewTreeNormalizer from the public API so hosts can reuse the same React/HTML-style node-name aliases.

0.3.1

• Automated patch bump.

0.3.0

• Add path node for SVG path stroking with optional progress animation.
• Add absoluteFill node (alias fill) for expanded background fills.
• Add stack.fit support (expand / loose).
• Add universal effect props (offsetX/offsetY, scale, rotation, opacity, blur) on any node.
• Text improvements:
  • style.gradient renders text with a gradient via ShaderMask.
  • style.fontStyle: 'italic' supported in addition to italic: true.
  • style.lineHeight aliases style.height.
• Image improvements:
  • asset: and file: source prefixes.
  • Optional imageResolver callback for custom image providers.
• Add customBuilders map for host-defined node types.
• Add video and audio placeholder nodes.

0.2.0

• Add jsr.ease.* easing helpers (linear, easeIn, easeOut, easeInOut, bounce, elastic, backIn, backOut).
• Add renderer effects from YoClip:
  • Radial gradients (gradient.type: 'radial').
  • Box shadows (decoration.shadows).
  • Blur node and blur property on containers.
  • clip: true on rounded containers.
  • Static 3D transforms (rotateX, rotateY, perspective) on containers.
  • Text shadows and textTransform (uppercase/lowercase).

0.1.1

• Automated patch bump.

0.1.0

• BREAKING CHANGE: Rename global JS object and channels from yoloit to jsr.
  • All widgets must use jsr.render(), jsr.onEvent(), jsr.fetchJson(), etc.
  • All internal bridge channels are now prefixed with __jsr_ instead of __yoloit_.
• Add JsRuntimeConfig.hostBootstrapJs so hosts can inject host-specific APIs (e.g., jsr.yoloit = {...}) without polluting the core runtime.
• Update example widgets and documentation to use the new jsr API.
• Add AGENTS.md, CLAUDE.md, and agent skills for widget authoring and engine maintenance.
