otel_get_it 0.1.0-beta.1

OpenTelemetry instrumentation for `package:get_it`. Wraps async singleton registration and lookup with spans so DI bootstrap cost is visible in your traces.

OpenTelemetry instrumentation for package:get_it.

final getIt = GetIt.instance;

// App startup: track DI bootstrap cost
getIt.tracedRegisterSingletonAsync<DatabaseService>(() async {
  return DatabaseService(await openDatabase('app.db'));
});
getIt.tracedRegisterSingletonAsync<AuthService>(() async {
  return AuthService(await FirebaseAuth.instance);
});

await getIt.tracedAllReady();

// Test teardown / hot reload
await getIt.tracedReset();

Spans:

• get_it register_async DatabaseService — covers the async factory's run time, parented to whatever span you're in
• get_it all_ready GetIt — the total bootstrap wait
• get_it reset GetIt
• get_it get_async <T> — for getAsync<T>() resolution
• get_it unregister <T>

All carry di.system = get_it, di.operation, di.type.

Why no sync get<T>() wrap?

Synchronous resolution is sub-microsecond on the hot path. A span per getIt<Foo>() would produce gigabytes of low-value trace data. Use the async variants when you want visibility, or wrap individual call sites yourself if you have a specific service whose lookup cost matters.

Suppression: runWithoutGetItInstrumentationAsync.
