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),
badgeCounter: 0),
navBarItem('Настройки',

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),
),

当我粘贴图像时，写入错误"；无法将参数类型"Image"分配给参数类型"IconData"&"；，

请帮忙。谢谢
