canvas_renderer_flutter 0.7.0

Flutter renderer for canvas_core paint operations and scene exports.

0.7.0

• Breaking: require canvas_core 0.8.x.
• No rendering behavior changes.

0.6.0

• Breaking: require canvas_core 0.7.x.
• Support the explicit component behavior version and data envelope introduced by canvas_core 0.7.0.

0.5.0

• Breaking: require canvas_core 0.6.x.
• Breaking: stop re-exporting CanvasFit and ContentBoundsPolicy. Import these core-owned types from canvas_core_runtime.dart.
• Breaking: require one typed CanvasSceneDocument in CanvasDocumentExporter.exportPng() and remove the documentJson input.
• Breaking: remove exporter-level renderBuilder support. Callers that use scene preparation must supply the already-prepared runtime scene.
• Render the supplied scene directly through CanvasRenderPipeline.build().
• Consume the CanvasViewportTransform returned directly by CanvasViewportPlanner.plan().

0.4.0

• Breaking: make FlutterTextPipeline implement the core TextMeasurer contract directly.
• Breaking: remove FlutterTextMeasurer, TextMetrics, and the previous FlutterTextPipeline.measure(TextSpec) API.
• Breaking: require a caller-owned FlutterTextPipeline when constructing CanvasRenderer and CanvasDocumentExporter.
• Breaking: remove fallbackFontFamilies from CanvasDocumentExporter; fallback fonts are configured on the supplied text pipeline instead.
• Dispose cached TextPainter instances during LRU eviction, cache clearing, and pipeline disposal.
• Dispose operation-scoped shadow, solid-color, and gradient text painters after painting.
• Add reusable clearCache() and idempotent terminal dispose() lifecycle behavior.
• Throw StateError when measurement or painting is attempted after pipeline disposal.
• Reject non-positive text-layout cache limits with ArgumentError in all build modes.

0.3.1

• Make PNG output image cleanup exception-safe.
• Document that export input images remain caller-owned.

0.3.0

• Breaking: make FlutterImagePool the sole owner of decoded images and stable intrinsic image metadata.
• Remove FlutterImageIntrinsics and the separate intrinsics method parameters.
• Expose decoded images through a live, read-only map.
• Add injectable image decoding with explicit ownership transfer.
• Dispose replaced, removed, stale, late, and retained image handles.
• Prevent older intrinsic and raster requests from overwriting newer state.

0.2.0

• Breaking: require canvas_core 0.4.x.
• Replace pre-expanded text with native double letter spacing.
• Forward letter spacing through measurement, caching, and painting.

0.1.1

• Expand the supported canvas_core range to include 0.3.x.
• No renderer behavior or API changes.

0.1.0

• Initial open-source release of canvas_renderer_flutter.
• Provides Flutter rendering, text measurement, decoded image caching, image intrinsic helpers, and PNG export support for canvas_core scenes.
• Includes optional ImageProvider helpers behind a separate import for apps that want to resolve common image refs across mobile and web.
