# startScreenShare()

> Starts a screen share from the local participant.

`startScreenShare(options?)`

Does nothing if there is no active meeting or `enable_screenshare` is disabled for the room or meeting token.

See the [react-native-daily-js README](https://github.com/daily-co/react-native-daily-js) for platform-specific setup instructions for [Android](https://github.com/daily-co/react-native-daily-js#android) and [iOS screen sharing](https://github.com/daily-co/react-native-daily-js#screen-sharing-on-ios).

Listen for [`local-screen-share-started`](/reference/react-native/events/media-events#local-screen-share-started) to confirm sharing is active, [`local-screen-share-stopped`](/reference/react-native/events/media-events#local-screen-share-stopped) when it ends, and [`local-screen-share-canceled`](/reference/react-native/events/media-events#local-screen-share-canceled) if the user dismisses the picker.

## Parameters

`options?: DailyStartScreenShare`

<ParamField body="screenVideoSendSettings" type="DailyVideoSendSettings | DailyScreenVideoSendSettingsPreset">
  Send settings for the screen video track. Accepts the same values as [`updateSendSettings()`](/reference/react-native/instance-methods/update-send-settings).
</ParamField>

## Return value

Returns `void`.

## Example

```javascript theme={null}
// Default screen share
call.startScreenShare();

// With custom send settings
call.startScreenShare({
  screenVideoSendSettings: 'motion-and-detail-balanced',
});
```
