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).

otel_flutter_secure_storage

OpenTelemetry instrumentation for package:flutter_secure_storage.

final fss = FlutterSecureStorage();

await fss.tracedWrite(key: 'auth.token', value: token);
final t = await fss.tracedRead(key: 'auth.token');
await fss.tracedDelete(key: 'auth.token');
await fss.tracedDeleteAll();

Each call emits a CLIENT span:

• name: secure_storage <op> <key>
• storage.system = flutter_secure_storage
• storage.operation = write / read / delete / deleteAll / containsKey
• storage.key = <key> (omitted on deleteAll)

Privacy

The stored value never appears on the span. Secure storage is for credentials, tokens, and other sensitive data — leaking it into traces would defeat the purpose.

For tracedRead, the result presence is also intentionally not surfaced — that could leak whether a particular key exists.

If you want even less detail (no keys either), use the suppression scope:

await runWithoutSecureStorageInstrumentationAsync(() async {
  await fss.tracedRead(key: 'auth.token');
});
