+    context: context,
+    builder: (context) => ScreenSelectDialog(),
+  );
+  if (source == null) {

+  }
+  print('DesktopCapturerSource: ${source.id}');

+    ScreenShareCaptureOptions(
+      sourceId: source.id,
+      maxFrameRate: 15.0,
+    ),

+  print('could not publish screen sharing: $e');
