How to detect hold and fastforward event in react native TVEventHandler

I am new to React Native. I want to know how can implement press and hold event for seek. I am able to get fastForward and press right events in React native layer by using below code.

_enableTVEventHandler() {
    this._tvEventHandler = new TVEventHandler();
    this._tvEventHandler.enable(this, function(cmp, evt) {
      if (evt && evt.eventType === 'right') {
        cmp.setState({board: cmp.state.board.move(2)});
      } else if(evt && evt.eventType === 'up') {
        cmp.setState({board: cmp.state.board.move(1)});
      } else if(evt && evt.eventType === 'left') {
        cmp.setState({board: cmp.state.board.move(0)});
      } else if(evt && evt.eventType === 'down') {
        cmp.setState({board: cmp.state.board.move(3)});
      } else if(evt && evt.eventType === 'playPause') {
        cmp.restartGame();
      }
    });
  }

Not able to get the hold fastforward or hold and right event to detect seek event. I am not sure it if its possible in RN layer. If not then how can i do the same in Android layer.

Thanks in advance
