Traces Exporter

Use tracesExporter in CXExporterOptions to receive native-exported trace batches as OTLP-style JSON maps over the Flutter bridge.

final options = CXExporterOptions(
  // ...other options...
  tracesExporter: (Map<String, dynamic> batch) {
    // Example: batch['resourceSpans'] -> scopeSpans -> spans
    debugPrint('Received trace batch with keys: ${batch.keys.toList()}');
  },
  enableSwizzling: true,
);

Typical payload shape (simplified):

• resourceSpans (array)
• resourceSpans[].scopeSpans (array)
• resourceSpans[].scopeSpans[].spans (array of span objects like traceId, spanId, name, timestamps, attributes)
