import EventBus from 'react-native-event-bus';

    super(props);
    const {tabLabel} = this.props;
    this.storeName = tabLabel;
    this.isFavoriteChanged = false;
  }

  componentDidMount(){

    });

      if(data.to === 0 && this.isFavoriteChanged){
        this.loadData(null,true);
      }
    });
  }

  componentWillUnmount(){
    EventBus.getInstance().removeListener(this.favoriteChangeListener);
    EventBus.getInstance().removeListener(this.bottomTabSelectListener);
  }
