hegeltest_flutter 0.9.1

Flutter integration for hegeltest — property-based testing powered by Hegel's native engine. Use with flutter_test instead of package:test.

0.9.1

• New: Add runHegelFlutterWidgetTest() standalone widget property runner returning a RunResult.
• New: Add LayoutSweepConfig.validate() to fail fast with ArgumentError on non-positive, non-finite, inverted, or empty sweep bounds and option lists.
• New: Add optional Generator<String>? textGenerator parameter to hegelFlutterMonkeyTest() for customizing SemanticsAction.setText inputs.
• Fix: Isolate widget Element, State, and RenderObject trees across property and shrinking iterations using KeyedSubtree(key: UniqueKey()) in hegelFlutterMonkeyTest() and hegelFlutterLayoutSweepTest(), and SizedBox.shrink(key: UniqueKey()) before each iteration in hegelFlutterWidgetTest().
• Fix: Capture pending Flutter framework exceptions (tester.takeException()) in hegelFlutterWidgetTest() and after invariant callbacks in hegelFlutterMonkeyTest() and hegelFlutterLayoutSweepTest() so framework errors trigger property shrinking, and drain remaining exceptions in finally.
• Fix: Inject MediaQuery and Directionality inside MaterialApp.builder in hegelFlutterLayoutSweepTest() so routes, dialogs, and overlays inherit swept viewport sizes, text scales, brightness, and keyboard insets instead of being overwritten by MaterialApp's root view query.
• Fix: Synchronize tester.view.viewInsets and tester.platformDispatcher overrides in hegelFlutterLayoutSweepTest() and reset all view/dispatcher overrides on teardown.
• Fix: Validate steps >= 0 and check tester.takeException() immediately after the initial pumpWidget in hegelFlutterMonkeyTest().
• Fix: Propagate machine.tearDown() failures in hegelFlutterStatefulTest() when the test body succeeded, and validate HEGEL_SEED as an integer.
• Fix: Automatically stage the bundled libhegel binary into .dart_tool/lib/ atomically under flutter test so tests run out-of-the-box without requiring HEGEL_LIBHEGEL_PATH.

0.9.0

• New: Bump hegeltest dependency to ^0.9.0, bringing tc.classify(), tc.cover(), sampledWeighted(), and oneOfWeighted() to Flutter
• New: Minimum distribution coverage assertions via tc.cover() with InsufficientCoverageException in Flutter tests
• New: Direct weighted sampling with sampledWeighted() and oneOfWeighted() combinators

0.8.0

• New: hegelFlutterMonkeyTest() — Accessibility/Semantics monkey fuzzing for Flutter widgets and entire apps
  • Traverses the active SemanticsOwner tree and discovers interactive accessibility nodes
  • Dispatches fuzzed actions (tap, longPress, scroll, setText, increase/decrease, dismiss)
  • Automatically shrinks failing action sequences to minimal reproducing steps with trace logs
  • Supports allowedActions filtering, stepInvariant, and invariant callbacks
• New: hegelFlutterLayoutSweepTest() — Comprehensive screen size and layout invariant sweep testing
  • Sweeps viewports across logical widths, heights, dynamic TextScaler font scales, LTR/RTL text directions, device pixel ratios, and keyboard insets
  • Automatically detects RenderFlex overflowed and framework layout errors
  • Shrinks breaking viewports and font scales to find minimal boundary failure conditions
  • Provides LayoutSweepConfig, LayoutSample, and LayoutOverflowException with automatic view size cleanup
• New: Re-export SemanticsAction from package:flutter/rendering.dart in barrel file

0.7.0

• New: Bump hegeltest dependency to ^0.8.0, bringing persistent counterexample database caching to Flutter
• New: Automatic .hegel/examples/ caching of failing counterexamples with instant replay on iteration 1
• New: Auto-derived databaseKey scoped to test descriptions across unit, widget, and stateful test runners
• New: Support database: false opt-out, HEGEL_DATABASE=0 env var, and custom databasePath directory
• Docs: Comprehensive database documentation and CI caching configuration in README

0.6.0

• New: Bump hegeltest dependency to ^0.7.0, bringing tc.collect() observation statistics API to Flutter
• Example: Update example/main.dart demonstrating tc.collect() in unit tests, widget configuration sweeps, and standalone runners

• Bump hegeltest dependency to ^0.5.0 (Native Assets integration)
• Native library now auto-resolved via Dart Build Hooks — no manual setup needed

0.2.0

• New: hegelFlutterStatefulTest() — stateful testing compatible with flutter_test
• Bump hegeltest dependency to ^0.4.0
