ethos 0.8.3

Measure accessibility coverage in Flutter apps using WCAG 2.2 specifications with Spec-Driven Development.

0.8.3

• ethos --version — new flag (--version / -V / ethos version) that prints the installed version and exits. Useful to confirm which version is active after dart pub global activate ethos.

0.8.2

• -p is now optional — all three subcommands default to the current working directory when --project-path is omitte.

0.8.1

• Fixed _ResolvedWidgetVisitor in deep_analyzer.dart to match the fixes already applied to widget_visitor.dart in 0.8.0.

0.8.0

• Flutter test integration — new package:ethos/ethos_test.dart barrel with matchers and helpers for use in dart test or flutter_test suites. Import path is separate from the main API so test utilities never reach production builds.

• analyzer 8.x compatibility fixes — several breaking AST API changes introduced in analyzer 8.x are now handled across all detectors and utilities:

  • NamedArgument.name is now a Token (not a Label) — reading the parameter name via token.toString() with a label?.name fallback for 7.x.
  • NamedArgument.argumentExpression replaces .expression as the canonical getter for the argument value — tried first with .expression fallback.
  • PositionalArgument no longer implements Expression — unwrapped via .argumentExpression before type checks.
  • NodeList<Argument> replaces NodeList<Expression> in ArgumentList.arguments — all argument iteration uses dynamic typing with duck-typed helpers.

0.7.0

• ethos watch subcommand — incremental re-analysis on file save. Performs a full scan on startup, then re-parses only the changed file and recomputes the report from the cached results of all other files. Prints the full report after each change with ▲/▼ coverage deltas and highlights findings in the modified file only.

0.6.0

• 2 new WCAG detectors (7 rules covered):

  • Non-text Content (1.1.1, Level A): detects images and icons without an accessible text alternative (Semantics(label:), semanticLabel, or explicitly marked as decorative).
  • Resize Text (1.4.4, Level AA): detects fixed textScaleFactor and textScaler values that ignore system text-size preferences.

• ethos init automatically generates a starter ethos.yaml with custom widgets and color definitions that require manual configuration.

• Public API for ethos init via WidgetDiscovery.discover() and EthosYamlGenerator.generate().

• Compliance levels updated: WCAG 1.1.1 added to A/AA/AAA, and WCAG 1.4.4 added to AA/AAA.

0.5.1

• Resolve absolute path issue for package_config.json

0.5.0

• Deep analysis mode: a new CLI flag and DeepAnalyzer API that uses AnalysisContextCollection to resolve the full project — cross-file references, class hierarchies, and type information. Detects widgets and accessibility issues that standard syntactic analysis misses entirely. Falls back to standard mode automatically when the project is not ready (no flutter pub get run).

0.4.0

• Improved compatibility with newer analyzer versions (up to 13.x), ensuring Ethos works reliably across supported releases.

• Added official desktop platform support (Windows, macOS, and Linux) and resolved analyzer/lint-related issues.

• Significantly enhanced color contrast detection by automatically extracting colors from ThemeData and supporting custom color_aliases in ethos.yaml, reducing indeterminate results in real-world applications.

• Introduced ColorAlias and ThemeExtractor to resolve design-system and theme-based colors into actual WCAG contrast calculations.

0.3.0

• CLI command renamed from accessibility-coverage to ethos.

0.2.0

• Built-in WCAG 2.2 specification with automatic project configuration via ethos.yaml; no external spec files required.

• Extensible design-system support through widget_aliases and per-rule customization through rule_overrides, allowing custom widgets to participate in accessibility analysis.

• Improved analysis accuracy with alias-aware detectors, precise source-level findings, explicit Indeterminate tracking, and better support for modern Dart syntax and widget detection patterns.

0.1.0

• Pure static analysis (AST) using package:analyzer and RecursiveAstVisitor to map Flutter widgets without runtime analysis.

• Transparent metrics: Rigorous classification of nodes into Pass, Fail, or Undetermined (for dynamic styles or Theme.of(context) inheritance).

• Complete decoupling: Detectors (SemanticLabels, Contrast, TouchTarget, Keyboard, FocusOrder) are registered independently in a DetectorRegistry.

0.0.1

• Initial MVP with 5 WCAG 2.2 coverage rules (semantics, contrast, touch targets, keyboard, focus)
• Spec-Driven Development with formal YAML specifications
• CLI tool with JSON, human, and markdown report formats
• Compliance level determination (A/AA/AAA)
• Full test suite and documentation
