I achieved a temporary fix by changing the source code for NavBar, adding a "numberOfLines={1}" prop, along with passing in some styling into the root scene. Is there a more elegant/permanent way to do this without changing the underlying source code (since this will get erased every time I update)?
/* NavBar.js */
...
_renderTitle(childState: NavigationState, index:number) {
return (
<Animated.Text
key={childState.key}
numberOfLines={1}
