fluttersdk_wind_diagnostics_contracts

Initial stable release. Neutral abstract contracts that let debug-tooling packages read Wind UI widget state at runtime without a compile-time dependency on fluttersdk_wind.

Added

• WindDebugResolver abstract class (lib/fluttersdk_wind_diagnostics_contracts.dart): single-method interface Map<String, Object?> resolve(Element element). Implementations live in fluttersdk_wind (production) and test fakes (debug-only). The returned map's key set is documented as the v1 frozen contract:

  • className: String (required when the widget is a W-prefixed widget with a non-empty className).
  • breakpoint: String (e.g. 'sm', 'md', 'lg').
  • brightness: String ('light' or 'dark').
  • platform: String (e.g. 'web', 'ios', 'android', 'macos').
  • states: List<String> (e.g. ['hover', 'focus']).
  • bgColor: String hex (e.g. '#3B82F6'); present only when resolved.
  • textColor: String hex; present only when resolved.
    Implementations MUST return const {} for elements that are not Wind widgets, guaranteeing a graceful no-op for consumers walking arbitrary widget trees.

• WindDebugRegistry static registry (lib/fluttersdk_wind_diagnostics_contracts.dart): process-global single-slot registration for the active WindDebugResolver. Wind installs its concrete resolver at app boot (gated by kDebugMode) via Wind.installDebugResolver(); debug-tooling consumers look up the current resolver via WindDebugRegistry.current. The registry exposes:

  • WindDebugRegistry.current getter (returns null when no resolver is registered).
  • WindDebugRegistry.register(resolver) (canonical install path; idempotent, most-recent-call wins).
  • WindDebugRegistry.resetForTesting() and WindDebugRegistry.registerForTesting(resolver) (both @visibleForTesting; test-only seams).

• 6 contract tests (test/fluttersdk_wind_diagnostics_contracts_test.dart): cover null-when-unregistered, register stores + lookup, idempotent register (last-wins), resetForTesting clears, registerForTesting overrides, and the contract assertion that resolver implementations return const {} for non-Wind elements.

• GitHub Actions workflows (.github/workflows/ci.yml, .github/workflows/publish.yml): CI runs flutter pub get + dart format --set-exit-if-changed + dart analyze + flutter test --coverage with an 80% line-coverage floor + flutter pub publish --dry-run. Publish runs on a SemVer tag push, validates, performs the OIDC publish to pub.dev, then creates a GitHub Release whose body is extracted from this CHANGELOG.

Why this package

Wind UI exposes 6 widget-state fields (className, breakpoint, brightness, platform, states, bgColor, textColor) that debug-tooling packages such as fluttersdk_dusk need to embed in their snapshot output. Shipping that handoff through fluttersdk_wind's own surface would force every debug-tooling package to compile-time depend on Wind (heavy, transitively pulls Flutter's rendering surface), and would force Wind to compile-time depend on every debug-tooling package it wants to feed.

This package breaks the loop. Both sides depend on the abstract contract here; neither side imports the other. The pattern mirrors Flutter's *_platform_interface convention (4.97M downloads on plugin_platform_interface as the canonical precedent).
