          items: [
            _bottomItem(Ids.home, 'ic_home_normal', 'ic_home_selected', 0),
            _bottomItem(Ids.information, 'ic_discovery_normal', 'ic_discovery_selected', 1),
            _bottomItem(Ids.news, 'ic_hot_normal', 'ic_hot_selected', 2),
            _bottomItem(Ids.mine, 'ic_mine_normal', 'ic_mine_selected', 3),
          ],

            _bottomItem(Ids.home, 'ic_home_normal', 'ic_home_selected', 0),
            _bottomItem(Ids.information, 'ic_discovery_normal', 'ic_discovery_selected', 1),
            _bottomItem(Ids.news, 'ic_hot_normal', 'ic_hot_selected', 2),
            _bottomItem(Ids.mine, 'ic_mine_normal', 'ic_mine_selected', 3),
          ],
