// For each view manager, we create a wrapper component that accepts all of the props available to
// the author of the universal module. This wrapper component splits the props into two sets: props
// passed to React Native's View (ex: style, testID) and custom view props, which are passed to the
// adapter view component in a prop called `proxiedProperties`.
// NOTE: React Native is moving away from runtime PropTypes and may remove ViewPropTypes, in which
// case we will need another way to separate standard React Native view props from other props,
// which we proxy through the adapter
