Channel List for PubNub Chat Components for React Native
Renders an interactive list of channels.
It can represent all channels of the application, only channels joined by the current user, all channels available to be joined, or whatever else is passed into it. A common pattern in chat applications is to render two instances of the component - one visible all the time to show joined channels, and another one hidden inside a modal with channels available to join. Make sure to handle the onChannelSwitched event to switch the current channel passed to the Chat provider.
