startGlobalSpan method

@override Future<Map<String, dynamic>?> startGlobalSpan({ required String name, Map<String, dynamic>? labels, required List<String> ignoredInstruments, })

Starts a global custom span on the native SDK. Returns null if the SDK refuses (e.g. another global span is active).

Implementation

@override
Future<Map<String, dynamic>?> startGlobalSpan({
  required String name,
  Map<String, dynamic>? labels,
  required List<String> ignoredInstruments,
}) async {
  // Null means the native SDK refused a new global span (e.g. one already
  // active — Q3). [PlatformException] is not caught here so callers can tell
  // bridge failures apart from an explicit null response.
  final dynamic result = await methodChannel.invokeMethod<dynamic>(
    'startGlobalSpan',
    <String, dynamic>{
      'name': name,
      'labels': labels,
      'ignoredInstruments': ignoredInstruments,
    },
  );
  if (result == null) return null;
  return Map<String, dynamic>.from(result as Map<dynamic, dynamic>);
}
