    this.currentIndex = 0,//选中第几个
    BottomNavigationBarType type,
    this.fixedColor,//文字颜色
    this.iconSize = 24.0,//icon图片大小
    })

/**
    const BottomNavigationBarItem({
    @required this.icon,//未选中图标
    this.title,//文字
    Widget activeIcon,//选中图标
    this.backgroundColor,// 测试发现type设置为shifting时，backgroundColor才有效
    })
