Write Default Text on Native-Base Input

I am calling a component like this by passing a string to it:

<TripsPage          startingPoint={startingPoint}        />

Now in this component, I have this label:

<Item fixedLabel><Input/></Item>

on the front-end, when we open this screen it is obviously empty. But I want the startingPointstring to appear on it as a default input value. Is that possible?
