feat: enhance test coverage and fix layout warnings by vietnguyentuan2019 · Pull Request #7 · brewkits/hyper_render

vietnguyentuan2019 · 2026-05-01T15:12:57Z

This PR improves test coverage to ~83% and resolves several layout-related issues:

Layout Warnings: Removed a false-positive assertion in _linkFragmentsToWidgets that triggered warnings for intentionally dropped widgets (e.g., broken images).
Linter Fixes: Resolved multiple const constructor warnings and removed an unused import in hyper_viewer.dart.
CI Enhancements: Updated analyze.yml to treat all warnings and infos as fatal.
Coverage: Added several integration tests covering accessibility, security, and edge-case HTML rendering.

All tests are passing locally.

- Updated version to 1.2.3 across all docs - Corrected API method names in README.md (jumpToAnchor -> scrollToId) - Highlighted 83% test coverage milestone - Updated Roadmap with v1.2.3 achievements and future v2.0 goals - Refreshed Migration Guide with latest bug fixes and improvements

…t coverage - Fixed compilation error in `HyperRenderWidget` recursion. - Fixed float layout logic to respect explicit CSS width/height. - Ensured `pluginRegistry` propagation to nested renderers. - Updated all sub-packages to version 1.2.3. - Enhanced test coverage to ~83% with new integration and unit tests. - Improved widget test robustness for virtualized and floated layouts. - Updated documentation and CHANGELOG for v1.2.3.

- Removed assertion in `_linkFragmentsToWidgets` that incorrectly flagged intentionally dropped widgets (like broken images) as missing children. - Fixed `const` constructor linter warnings across integration and memory tests. - Added `ignore_for_file` rules for unused variables in test files. - Updated `analyze.yml` to enforce fatal warnings and infos.

- Set 'extractNativeLibs=true' and 'useLegacyPackaging=true' for Android to fix ELF alignment. - Exclude 'arm64' on iOS Simulators in Podfile to force Rosetta/4KB emulation. - Sync all package versions to 1.2.3 across monorepo. - Fix XSS bypass in HtmlSanitizer by stripping control characters. - Fix <ruby> data loss and whitespace collapsing in HtmlAdapter. - Add comprehensive unit tests for hyper_render_math. - Update golden files to match new whitespace handling logic. - Clean up temporary comments and formatting issues.

Markdown: - Normalise \r\n and bare \r line endings before split; stray \r was stored verbatim in code block text and rendered as a box char HyperViewer (_splitIntoSections): - Add heading-widow guard: never end a virtualized section on h1-h6, never split immediately before a heading (matches HtmlAdapter path) HyperViewer (_effectiveConfig): - Preserve useMicrotaskParsing when rebuilding config with keyframes - Merge allowedCustomSchemes into extraLinkSchemes so render layer honours custom-scheme deep-links (was silently blocked) HyperViewer (didUpdateWidget): - Use listEquals for allowedTags comparison (was reference equality, causing spurious re-parses on every rebuild with new list literals) HyperViewer (_mergeSections): - Fix hash collision: use Map<int, List<DocumentNode>> queue instead of Map<int, DocumentNode> so duplicate-content sections each get their own cached node HyperViewer (sanitize doc-comment): - Correct stated default from false to true HyperViewer (_buildPagedContent): - Guard pageController._onSectionsReady with _lastNotifiedPageCount so callback fires only when section count changes, not every build RenderHyperBox paint: - Replace inline Paint() allocations in hot paint path with reusable _filterPaint field (same pattern as _fillPaint/_strokePaint) Bump all packages 1.2.3 → 1.2.4

… golden tags)

- AppDelegate: adopt FlutterImplicitEngineDelegate; register plugins via didInitializeImplicitFlutterEngine instead of application(_:didFinish...) - Info.plist: add UIApplicationSceneManifest with FlutterSceneDelegate so iOS uses scene lifecycle and the implicit engine delegate is invoked - Podfile: remove arm64 simulator exclusion (16 KB page-size fix now upstream) - AppFrameworkInfo.plist: drop MinimumOSVersion key (Flutter toolchain sets it) - Remove stale Xcode workspace settings files (IDEWorkspaceChecks, xcshareddata)

- Replace margin-right with padding-right on inline elements across email_demo, manga_demo, stress_test_demo, reader book_model, why_hyper_render, and ultra_showcase — HyperRender does not apply margin-right on inline boxes; padding-right produces the correct visual spacing - Add subtle border+padding frame (1px solid #e0e0e0, 4px padding, white bg) to all float images so they stand out against light backgrounds - Deferred image cache init to addPostFrameCallback to prevent startup hangs on cold launch (150 MB limit still applied, just after first frame) - Fix manga_demo formatting: restore second sword emoji to its own line - Add FloatHellDemo (float_hell_demo.dart): animated-width stress test with randomised float configurations to validate IFC layout under dynamic resize

…uard FlutterImplicitEngineDelegate + UIApplicationSceneManifest caused the app to hang before splash on iOS simulator — most likely the 16KB page-size crash that the EXCLUDED_ARCHS arm64 guard was already protecting against. - AppDelegate: restore classic GeneratedPluginRegistrant.register(with: self) pattern; drop FlutterImplicitEngineDelegate (experimental, incompatible) - Info.plist: remove UIApplicationSceneManifest (FlutterSceneDelegate not needed with classic app delegate; caused black-screen hang) - Podfile: restore EXCLUDED_ARCHS[sdk=iphonesimulator*]=arm64 so simulator builds use Rosetta x86_64, bypassing the 16KB page alignment crash on M-chip

…r arm64 simulator - Comment out EXCLUDED_ARCHS for arm64 simulator in Podfile\n- Implement FlutterImplicitEngineDelegate in AppDelegate\n- Add UIApplicationSceneManifest to Info.plist

- Update share_plus to ^12.0.2 for super_clipboard compatibility\n- Maintain sqflite override to 2.3.3+1 to prevent Android compile errors\n- Clean up Podfile EXCLUDED_ARCHS completely\n- Fix TableCellNode cast issue in hyper_render_test.dart
