Initial zoom level in React Native Maps

I'm using react-native-maps library.

This is my initial lat and long ,

<MapView
   style={{width: '100%', height: 250}}
   initialRegion={{
     latitude: 6.795218101812615,
     longitude: 79.9008869173333,
     latitudeDelta: 6.795218101812615,
     longitudeDelta: 79.9008869173333,
  }}>

But It is not zoomed. Is there any way to set the initial zoom value?

You can use minZoomLevel prop to give the initial zoom value. You can find more information in This Link

<MapView
   style={{width: '100%', height: 250}}
   minZoomLevel={15}
   initialRegion={{
     latitude: 6.795218101812615,
     longitude: 79.9008869173333,
     latitudeDelta: 6.795218101812615,
     longitudeDelta: 79.9008869173333,
  }}>
