canvas_editor_flutter 0.11.1

Complete Flutter scene editor for canvas_core documents with turnkey UI and composable editing, asset, image-import, image-tools, and export capabilities.

0.11.1

• Add the optional image_tools.dart capability entrypoint.
• Add the provider-neutral BackgroundRemovalPort and typed background-removal results.
• Add backgroundRemovalExtension for host-owned background removal inside the standard Image inspector.
• Keep background removal target-safe across asynchronous selection, source, target, field-editability, and prepared-scene changes.
• Commit successful replacements through the registered CanvasFields.imageSource field path so normal field policy and undo/redo remain authoritative.
• Keep image processing, persistence, provider lifecycle, byte handling, and cleanup of unreferenced outputs outside Canvas.

0.11.0

• Breaking: image import no longer participates in the exclusive InspectorBuilder chain. It contributes source controls to the standard inspector instead, so an exclusive inspector override now suppresses image import content together with the intrinsic inspector.
• Add InspectorSectionBuilder and EditorSurfaceFeatures.inspectorSections for additive standard-inspector content composed in extension registration order.
• Keep additive inspector content inside the standard inspector card and before intrinsic field controls.
• Make asynchronous image replacement target-safe by rejecting stale results after selection, source, target, or field-editability changes.

0.10.0

• Breaking: remove InspectorFieldRow.forceDisabled and InspectorFieldRow.disabledReasonOverride; registered field editability now flows through FieldState.disabledReason.
• Add EditorDocumentAdapter.fieldEditDisabledReason(...) for source-document-aware registered literal edit restrictions.
• Enforce source-document field denial in EditorRuntime.commitField() using the current canonical transaction state.
• Apply source-document editability to scene-level registered fields.
• Export kSceneFieldsId through the public extensions.dart entrypoint.

0.9.0

• Breaking: require canvas_core 0.8.x and canvas_renderer_flutter 0.7.x.
• Breaking: remove PngExportAvailability; configure canShare and canSave directly on PngExportCapability.
• Breaking: remove JsonExportAvailability; configure canCopy and canSave directly on JsonExportCapability.
• Breaking: remove the editor-owned JsonMap alias. Use Map<String, Object?> or a domain-owned alias where needed.
• Adopt the narrowed NodeEditingX runtime editing surface.
• No intended editor, rendering, preparation, or export behavior changes.

0.8.0

• Breaking: replace the split EditorExports and PngOutputPort PNG contracts with one host-owned PngExportPort.
• Pass both the canonical editable scene and the prepared render scene to PNG export hosts.
• Move final PNG resource preparation, rendering, policy, and output ownership behind the host export port.
• Keep scene JSON export based on the canonical editable scene.
• Update the runnable example to demonstrate host-owned PNG rendering and sharing through PngExportPort.

0.7.0

• Breaking: require canvas_core 0.7.x.
• Breaking: require canvas_renderer_flutter 0.6.x.
• Support the explicit component behavior version and data envelope introduced by canvas_core 0.7.0.

0.6.0

• Breaking: remove the redundant EditorActionIds.duplicateGroup and EditorActionIds.deleteGroup actions.
• Breaking: require EditorActionDispatcher to receive a non-null EditorActionContext.
• Keep the generic Duplicate and Delete actions working for groups and leaf nodes.

0.5.0

• Breaking: require canvas_core 0.6.x and canvas_renderer_flutter 0.5.x.
• Breaking: replace EditorExtension.renderBuilder and StaticEditorExtension.renderBuilder with scenePreparer.
• Breaking: reject extension compositions with more than one non-null ScenePreparer by throwing StateError.
• Breaking: change EditorExports.renderPng() to accept a typed preparedScene instead of scene JSON.
• Resolve source documents through EditorDocumentAdapter, apply optional scene preparation once, and then call CanvasRenderPipeline.build().
• Preserve canonical editable scenes for editing, history, persistence, and scene JSON export while using prepared runtime scenes for drawing and PNG export.
• Remove the PNG scene JSON encode/decode round trip.
• Consume the CanvasViewportTransform returned directly by CanvasViewportPlanner.plan().

0.4.0

• Breaking: require canvas_core 0.5.x and canvas_renderer_flutter 0.4.x.
• Use one FlutterTextPipeline for both core text measurement and Flutter text painting.
• Remove the editor's separate FlutterTextMeasurer and session-long core text measurement cache.
• Clear cached text layouts after new fonts load and before scheduling layout invalidation.
• Dispose the editor-owned text pipeline when the editor session is destroyed.

0.3.1

• Use FlutterImagePool as the editor's single image and intrinsic-state owner.
• Remove duplicate image-intrinsics lifecycle management.
• Require canvas_renderer_flutter 0.3.x.

0.3.0

• Breaking: remove EditorExportFit and use the shared CanvasFit type from canvas_core.
• Keep the default export fit as CanvasFit.contain.

0.2.0

• Breaking: require canvas_core 0.4.x and canvas_renderer_flutter 0.2.x.
• Preserve fractional letter spacing through editing and history.
• Use quarter-pixel letter-spacing controls in the inspector.

0.1.1

• Made image replacement actions responsive in narrow inspector layouts.
• Added compact Gallery and Camera actions with enlarged-text coverage.

• Added selection, movement, inspection, layers, undo and redo.
• Added extension points for custom documents, rendering, fields, actions, and editor chrome.
• Added optional image import, PNG export, and JSON export capabilities.
• Added English-language editor UI.
