React Native Mapbox gl Initial Center Coordinates

So I am trying to set my initial center coordinates for mapbox so they are not 0,0. On the api it says mapbox expects a prop of

initialCenterCoordinate object  Optional    Initial latitude/longitude the map will load at.    { latitude:0, longitude: 0 }

So I am doing

<Mapbox    initialCenterCoordinate={latitude: 40.444328, longitude: -79.953155} .... other props/>

This is giving me an error on that line saying unexpected token, expecting }.

Whenever I do something like

<Mapbox    initialCenterCoordinate={{latitude: 40.444328, longitude: -79.953155}} .... other props/>

It still sets my initial spot to 0,0. Anyone have any ideas?
