sdui_engine 0.6.0

A production-grade Server-Driven UI (SDUI) framework for Flutter. Build hyper-dynamic, completely remote home screens using clean JSON payloads and declarative architectures.

0.6.0

• Extensibility Upgrade: Added customSectionBuilders to SduiConfig and SectionRegistry so developers can inject massive, fully custom root-level Sections directly from the engine parser, dropping the rigidity of default sections.
• Resilience Layer: Formally introduced errorWidgetBuilder mapped sequentially throughout SduiScreen. Unpredictable schemas and component widget crashes are gracefully swept into explicit error widgets instead of bricking the engine stream.
• UI Purity: Reverted experimental app-specific HeaderSection alterations back to neutral framework-level styles to maintain an unopinionated core while the example application showcases proper Extensibility overrides.
• Demonstration Polish: Reflected precise, crisp new visual screenshots (sdui_demo.png) on pub.dev. Resolved remaining opacity deprecation flags.

0.5.0

• Major Release: Complete Architecture Overhaul
• Interaction Delegation Model: Embedded native SduiAction blocks and decoupled route handling natively to your application leveraging SduiActionHandlerProvider.
• Explicit Strict Types: Dropped global states inside the parser schema. SduiSectionConfig constructors explicitly pass down a strictMode boolean toggle enforcing unbreakable configurations during Development.
• Aggregated UX Validation: Injected ValidationResult objects silently gathering warnings instead of immediately interrupting parsing trees upon minor misspellings.
• Native Fallbacks DX: Rewrote raw missing component errors aggressively out of the engine. The system natively drops a vibrant SduiDebugOverlay dynamically catching unknown elements natively for supreme dev-mode observability.
• Premium Example Replacements: Obliterated generic layout examples and rolled out the hyper-modern complete swiggy_home.json example architecture natively simulating realistic full-scale SDUI infrastructure.

0.4.1

• Polish: Removed speculative roadmap from README.md and updated the layout demonstration asset with a new GIF.

0.4.0

• Feature: Added SduiConfig.fromJsonAsync() to enable deep JSON parsing on background microtasks, ensuring 60fps scrolling without main-thread jank when resolving massive SDUI payloads.
• Feature: Introduced native pagination APIs! Added hasMore and nextPageUrl schema definitions to ContentListSectionConfig and ActionGridSectionConfig.
• Feature: Wired onLoadMore: (section, url) callback into SduiScreen mapping engine natively bubbling scroll edge notifications from your remote layouts directly to your root application.
• Performance: Implemented aggressive deterministically hashed _cache mapping natively resolving identical JSON branches in ComponentRegistry in O(1) time without massive re-allocations.

0.3.2

• Fix (Docs): Explicitly renamed the layout demonstration asset to permanently bypass upstream pub.dev caching walls.
• Polish: Stripped default Flutter boilerplate scaffolding and tightened pubspec.yaml definitions to match production-grade expectations.

0.3.1

• Fix: Appended version query parameters manually into the README.md image tags to bypass GitHub CDN caching so the updated demo GIF successfully propagates on pub.dev.
• Docs: Updated installation string to bounds 0.3.1.

0.3.0

• Major Architecture Upgrade: Evolved from a simple layout builder to a production-grade Server-Driven UI (SDUI) Framework.
• Validation Layer (JsonParserUtils): Added strict primitive coercers to protect the parsing engine from malformed remote JSON schema data types (e.g. string integers gracefully casted).
• SDUI Identity (ValueKey): SduiScreen now automatically maps explicit rendering keys to all Sections utilizing the JSON id parameter. This prevents state loss and animation jank during remote refetches.
• Observability (SduiLogger): Included a built-in diagnostic logging toggle natively inside SduiConfig.fromJson(json, debugMode: true) to actively print component mapping boundaries or warn when generic fallback builders drop unknown elements.
• Example Enhancements: Created a new application tab fully loading mock_server_layout.json into the engine natively via HTTP-simulated asset fetches.

0.2.1

• Docs: Updated README.md to reflect the latest 0.2.1 version in installation instructions.

0.2.0

• Major Feature (Server-Driven UI): SduiConfig.fromJson(json, componentRegistry: ...) is now entirely supported! You can define your home layouts remotely and safely map JSON types to widgets.
• Architecture Change: Separated layout structure (SectionRegistry) and layout content constraints (ComponentRegistry) to ensure robust parsing boundaries.
• Component Abstraction: Removed tight Widget object dependency inside standard section models (ActionGridSectionConfig, ContentListSectionConfig, etc.), swapping them with data-oriented ItemConfig implementations for deep JSON serialization flexibility.
• Migration / Compat: Wrapped legacy direct-widget instances automatically into WidgetItemConfig instances for a backward-compatible and smooth transition.

0.1.2

• Fix: Constrained the README demo GIF dimensions so it scales beautifully on desktop pub.dev displays.

0.1.1

• Fix: Fixed visual demo rendering on pub.dev due to URL encoding issues and bumped package snippet documentation.

0.1.0

• Major Feature: Added 3 production-ready Prebuilt Layout Templates (EcommerceTemplate, DashboardTemplate, SocialFeedTemplate).
• Completely overhauled the example application into a production-grade multi-tab layout.
• Rewrote package documentation and README.md to be highly comprehensive with visual demos.

0.0.3

• Renamed docs directory to doc to comply with pub.dev package layout conventions.

0.0.2

• Added fine-grained control for section spacing.
• Exported package APIs correctly for better integration.
• Improved package metadata and resolved static analysis warnings.

0.0.1

• Initial release of the Modular Home Screen library.
• Added orchestrator engine SduiScreen powering a declarative layout configuration via SduiConfig
• Added standard sections definitions: BannerSectionConfig, ActionGridSectionConfig, ContentListSectionConfig, DividerSectionConfig.
• Core layout engine implementation supporting fully dynamic injecting of CustomSectionConfig.
• Theme styling capabilities overridden by SduiThemeDelegate.
