ethos 0.4.0

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

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
