otel_google_sign_in

OpenTelemetry instrumentation for package:google_sign_in (v7 API).

final gsi = GoogleSignIn.instance;

await gsi.tracedInitialize();
final account = await gsi.tracedAuthenticate();
await gsi.tracedSignOut();

Each call opens a CLIENT span named google_sign_in <op> with:

• auth.system = google_sign_in
• auth.operation = initialize / authenticate / attempt_lightweight_authentication / sign_out / disconnect
• auth.provider = google.com
• enduser.id — the user's Google account ID, on successful authentication (opt-out via recordUserId: false)

Failures record the exception and set span status to error (GoogleSignInException included, so canceled and misconfigured flows are visible in traces).

tracedAttemptLightweightAuthentication mirrors the underlying nullable-Future contract: a null return means no authentication attempt was possible, and no span is recorded.

Attribute keys are exposed as the GoogleSignInSemantics enum. tracedGoogleSignInCall<R> is the generic helper behind the extension methods, usable for custom operations.

Suppression: runWithoutGoogleSignInInstrumentation / runWithoutGoogleSignInInstrumentationAsync.
