flutter_api_observability 1.1.0

A production-grade Flutter API Observability Toolkit providing real-time request history, endpoint performance statistics, sensitive data redaction, error normalization, and health reporting for Flutt [...]

Changelog

1.1.0

• Added ApiGuardInterceptor for integrating flutter_api_observability with existing Dio instances without creating a second HTTP client.
• Added Request History (api.history) storing typed ApiRequestRecord items with unique Request IDs (API-0001), timestamps, durations, status codes, retry counts, and redacted payloads.
• Added History Memory Management with maxHistoryEntries (default 100), FIFO eviction, and maxHistoryBodyLength (default 4096) payload truncation.
• Added Endpoint Performance Statistics (ApiEndpointStats) including request volume, success rates, average duration, median duration, status code distributions, and consistently slow endpoint detection.
• Added History Filtering through api.failedRequests, api.slowRequests, byEndpoint, byStatusCode, and byMethod.
• Added Diagnostic Snapshot Export through api.exportDiagnostics() with JSON-safe health metrics, endpoint statistics, and recent request history.
• Added History & Health Reset Operations through api.clearHistory(), api.resetHealth(), and api.resetDiagnostics().
• Enhanced Sensitive Data Redaction with expanded default keys including token, password, authorization, access_token, refresh_token, secret, client_secret, api_key, bearer, cookie, set-cookie, credit_card, and cvv, with case-insensitive matching.
• Enhanced Structured Logging with unique Request IDs and retry diagnostics including attempt count, failure reason, and backoff delay.
• Added support for observing existing Dio clients through ApiGuardInterceptor.
• Upgraded the Flutter Example App to an interactive API observability dashboard.
• Expanded automated coverage to 46 tests, including history, request IDs, endpoint statistics, retries, redaction, payload truncation, diagnostics export, interceptor integration, security attacks, and stress testing.
