@override
api.Tracer getTracer(String name, {String? version = ''}) {
  final key = '$name@$version';
  return _tracers.putIfAbsent(
      key,
      () => Tracer(
          _processors,
          _resource,
          _sampler,
          sdk.DateTimeTimeProvider(),
          _idGenerator,
          sdk.InstrumentationLibrary(name, version),
          spanLimits: _spanLimits));
