stack_board_plus: ^0.0.7 copied to clipboard

Bug Fixes

• Fixed item position jump when updating an item; preserves original position/size/rotation reliably in StackItemCase interactions.
• Fixed background resizing behavior in the example so width/height updates apply correctly.
• Removed stray shadows from item cases in the example for a cleaner default look.

New

• Added elevation to StackBoardPlus to control the canvas Material elevation. Default is 1.0.
• Example updated with Background Settings slider to adjust canvas elevation live.
• Added layering APIs in controller:
  • moveItemOnTop, moveItemToBottom, moveItemForward, moveItemBackward, moveItemToIndex.
• Example now includes a Layers drawer showing a live, visual layer list with per-layer actions (to top/bottom, up/down) and item previews (text, image, color, drawing, shape).

Bug Fixes

• Fixed the bug where double-clicking on shape items directly opened the dialog box - now properly handles dynamic shape interaction behavior.

Code Refactoring & Architecture

• Completely refactored example application from a massive 3311-line single file into a clean, modular architecture.
• Organized codebase into logical directories: models/, pages/, dialogs/, widgets/, mixins/, and utils/.
• Improved code maintainability and debugging experience with clear separation of concerns.
• Enhanced project structure for better development workflow and team collaboration.

• Added StackShapeItem, StackShapeData, and related classes to support geometric shapes (rectangle, circle, rounded rectangle, line, star, polygon, heart, half-moon).
• Shape items support fill color, stroke color, stroke width, opacity, tilt, flipping, and endpoints (for polygons/stars).
• Shape items are fully integrated with the stack board system and support all item management features.
• Extensible shape editing interface via StackShapeCase and custom editor builder.
• Example app updated to demonstrate adding and editing shape items.

New Feature: Drawing Mode

• Added StackDrawItem, StackDrawContent, and StackDrawCase to support a fully customizable drawing/canvas mode.
• Drawing items support undo, redo, clear, export/import as JSON, and full DrawingBoard configuration (pan, zoom, background, border, gradient, etc.).
• Drawing mode is integrated with the stack board system and supports all item management features.
• Example and documentation updated to demonstrate drawing import/export and customization.

Enhanced Import/Export

• Improved JSON serialization for drawing and other stack items.
• Added placeholder and structure for robust import/export of drawing data (with future extensibility for deserialization).

Bug Fixes & Improvements

• Fixed and cleaned up import statements across the codebase for better modularity and package structure.
• Refactored helper files and removed unused/duplicate files.
• Improved type safety and null handling in helpers.
• Enhanced action helpers for stack items, including better type detection and custom action support.

Documentation

• Added/updated guides for drawing customization, enhanced movement, and text customization.
• Improved code comments and usage examples for new features.
