BottomNavigationBar(
        elevation: 10,
        type: BottomNavigationBarType.fixed,
        backgroundColor: Color(0xFFFBFBFB),
        showSelectedLabels: false,
        showUnselectedLabels: false,
        items: <BottomNavigationBarItem>[
          BottomNavigationBarItem(
            icon: Column(
              children: [
                Text(
                  AppLocalizations.of(context)!.redeem,
                  style: Styles.grey13Medium,
                )
              ],
            ),
            activeIcon: Column(
              children: [
                Text(
                  AppLocalizations.of(context)!.redeem,
                  style: Styles.blue13Medium,
                )
              ],
            ),
            label: 'Redeem',
          ),
        ],
        currentIndex: _currentTab,
        onTap: _onItemTapped,
      )

我们尝试更改叠加层，但我没有在 BottomNavigationBar 和 BottomNavigationBarItem 中找到叠加层属性
