otel_flutter_secure_storage 0.2.0

OpenTelemetry instrumentation for `package:flutter_secure_storage`. Wraps secure-storage reads / writes with key-aware spans, NEVER recording the value (credentials).

Changelog

0.2.0 - 2026-08-10

Changed

• flutter_secure_storage constraint widened to >=9.0.0 <12.0.0 (verified against 9.2.4 and 11.0.0).
• storage.* attribute keys are now the exported SecureStorageSemantics enum (OTelSemantic) instead of raw string literals. Emitted keys are unchanged.

Added

• example/example.md.
• Dartdoc for the suppression API.

0.1.0-beta.1 - 2026-05-16

Added

• Extension methods on FlutterSecureStorage: tracedWrite, tracedRead, tracedDelete, tracedDeleteAll, tracedContainsKey. Each opens a CLIENT span named secure_storage <op> <key> with storage.system=flutter_secure_storage, storage.operation, storage.key.
• Values are never recorded on the span — by definition, secure storage holds credentials and sensitive data.
• tracedSecureStorageCall<R>({operation, key, invoke}) — generic helper for testing or custom backends.
• Zone-scoped suppression (runWithoutSecureStorageInstrumentation and the async variant).
• 4 tests via the generic helper (span shape with key, span shape without key, exception path, suppression scope).
