/**
 * The chat connection listener.
 *
 * For the occasion of onDisconnected during unstable network condition, you
 * don't need to reconnect manually, the chat SDK will handle it automatically.
 *
 * There are only two states: onConnected, onDisconnected.
 *
 * Note: We recommend not to update UI based on those methods, because this
 * method is called on worker thread. If you update UI in those methods, other
 * UI errors might be invoked. Also do not insert heavy computation work here,
 * which might invoke other listeners to handle this connection event.
 *
 * Register:
 *  ```typescript
 *  let listener = new (class s implements ChatConnectionListener {
 *    onTokenWillExpire(): void {
 *      console.log('ConnectScreen.onTokenWillExpire');
 *    }
 *    onTokenDidExpire(): void {
 *      console.log('ConnectScreen.onTokenDidExpire');
 *    }
 *    onConnected(): void {
 *      console.log('ConnectScreen.onConnected');
 *    }
 *    onDisconnected(errorCode?: number): void {
 *      console.log('ConnectScreen.onDisconnected', errorCode);
 *    }
 *  })();
 *  ChatClient.getInstance().addConnectionListener(listener);
 *  ```
 * Unregister:
 *  ```typescript
 *  ChatClient.getInstance().removeConnectionListener(listener);
 *  ```
