otel_shared_preferences 0.1.0

OpenTelemetry instrumentation for `package:shared_preferences`. Extension methods on SharedPreferences that wrap write/remove/clear calls with key-value-store spans.

Changelog

0.1.0 - 2026-08-10

Added

• Extension methods on SharedPreferences: tracedSetString, tracedSetInt, tracedSetBool, tracedSetDouble, tracedSetStringList, tracedRemove, tracedClear. Each opens a CLIENT span named shared_prefs <op> <key> with storage.system=shared_preferences, storage.operation, storage.key.
• Reads (getString, getInt, etc.) are intentionally NOT wrapped — they're synchronous and very fast, so the overhead isn't worth it for typical apps. File an issue if you need them.
• Zone-scoped suppression helpers (runWithoutSharedPreferencesInstrumentation and the async variant) mirroring the rest of the OSS wrappers.
• Tests use SharedPreferences.setMockInitialValues; no real preferences backend needed.
