在自定义的底部导航菜单中添加SVG

如何解决在自定义的底部导航菜单中添加SVG

美好的一天。我需要在自定义图标之间粘贴svg图像。 在Flutter中自定义BottomNavigationBarItem。 我无法在自定义图标之间粘贴图像。 怎么做，

enter image description here

我的代码

class NavBarCustomer extends StatefulWidget {
@override
_NavBarCustomerState createState() => _NavBarCustomerState();
}

class _NavBarCustomerState extends State<NavBarCustomer> {
int _itemIndex = 0;
final List<Widget> _pages = [
HomeScreenCustomer(),AllRequests(),NewRequest(),NotificationPage(),MainSettings(),];

 @override
 Widget build(BuildContext context) {
 return Scaffold(
  body: _pages[_itemIndex],bottomNavigationBar: BottomNavigationBar(
    backgroundColor: Colors.white,selectedItemColor: Color(0xFF606060),unselectedItemColor: Color(0x80606060),type: BottomNavigationBarType.fixed,items: <BottomNavigationBarItem>[
      navBarItem('Главная',index: 0,icon: CustomIcons.home,firstColor: Color(0xFF02EFFD),secondColor: Color(0xFF48AFFD)),navBarItem('Мои заявки',index: 1,icon: Icons.check_circle_outline,firstColor: Color(0xFF34F8DA),secondColor: Color(0xFF43E980),badgeCounter: 0),navBarItem('',iconImage: Image.asset('assets/images/adding-icon.png')),navBarItem('Уведомления',index: 3,icon: CustomIcons.notification,firstColor: Color(0xFFFFBCDE),secondColor: Color(0xFFFC337C),navBarItem('Настройки',index: 4,icon: CustomIcons.settings,firstColor: Color(0xFFA3D5FF),secondColor: Color(0xFF6581D2)),],currentIndex: _itemIndex,onTap: (index) => setState(() {
      _itemIndex = index;
    }),),);
     }

  BottomNavigationBarItem navBarItem(String title,{int badgeCounter = 0,IconData icon,Image iconImage,double iconSize,Color firstColor,Color secondColor,int index}) {
  return BottomNavigationBarItem(
  title: Text(title,style: TextStyle(
              color: Color(
                  0xFF606060 - ((index == _itemIndex) ? 0 : 0x90000000)),fontSize: 11.w,fontWeight: FontWeight.w500))
      .padding(EdgeInsets.only(top: 7.w)),icon: Stack(
    alignment: Alignment.topRight,children: <Widget>[
      Opacity(
        opacity: (index == _itemIndex) ? 1 : 0.5,child: RoundedGradientIcon(
          iconSize: iconSize,firstColor: firstColor,secondColor: secondColor,icon: icon,radius: 30.w,Visibility(
        visible: badgeCounter != 0,child: Container(
          padding: EdgeInsets.all(1.w),height: 15.w,width: 15.w,alignment: Alignment.center,child: AutoSizeText(
            badgeCounter.toString(),minFontSize: 6,style: TextStyle(
                fontSize: 10.w,color: Colors.white,fontWeight: FontWeight.bold),decoration: BoxDecoration(
            color: Color(0xFFFF0000),borderRadius: BorderRadius.circular(100),

粘贴图像时，写入错误“无法将参数类型'Image'分配给参数类型'IconData'。”

请帮助。谢谢。

解决方法

尝试使用ImageIcon代替IconData。
