Learn how to preview user camera and audio before joining a Zoom Video SDK session using VideoView elements.

Preview


Before joining a session, you can give users a preview of their video and audio by starting the camera and microphone locally. The local video and audio track can be accessed through the `ZoomVideo` import.

## Preview camera

To preview a camera, create a ZoomView video element where you want the video preview to be displayed.

```dart
VideoView(
  user: fullScreenUser.value,
  hasMultiCamera: false,
  sharing: sharingUser.value == null
    ? false
    : (sharingUser.value?.userId == fullScreenUser.value?.userId),
  preview: true,
  focused: false,
  multiCameraIndex: "0",
  videoAspect: VideoAspect.Original,
  fullScreen: false,
  ),
```
