【问题描述】：
我是 Flutter 的新手，我在处理以下情况时遇到了困难。我创建了一个带有不同小部件的页面，并且我还在它自己的文件中创建了底部导航，但我无法将创建的页面添加到特定的底部导航项。在上面的代码中，我想将页面添加到发现底部导航中。
我底部导航的代码是：
MyBottomNavigation extends StatefulWidget {
@override
_MyBottomNavigationState createState() => _MyBottomNavigationState();
}
class _MyBottomNavigationState extends State<MyBottomNavigation> {
int _currentIndex = 0;
@override
Widget build(BuildContext context) {
return BottomNavigationBar(
selectedLabelStyle:
TextStyle(fontFamily: 'Circular', fontSize: kBottomNavFontSize),
unselectedLabelStyle: TextStyle(
fontFamily: 'Circular',
fontSize: kBottomNavFontSize,
),
type: BottomNavigationBarType.fixed,
backgroundColor: kPrimaryColor,
iconSize: kBottomNavIconSize,
currentIndex: _currentIndex,
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(FontAwesomeIcons.home),
label: 'Sermons',
),
BottomNavigationBarItem(
icon: Icon(FontAwesomeIcons.binoculars),
label: 'Discover',
),
BottomNavigationBarItem(
icon: Icon(CupertinoIcons.heart_solid),
label: 'Giving',
),
BottomNavigationBarItem(
icon: Icon(CupertinoIcons.calendar_today),
label: 'Events',
),
BottomNavigationBarItem(
icon: Icon(CupertinoIcons.person_fill),
label: 'Profile',
),
],
selectedItemColor: Color(0xFFc06014),
onTap: (index) {
setState(() {
_currentIndex = index;
});
},
);
}
}
我页面的代码是：
class Discover extends StatefulWidget {
@override
_DiscoverState createState() => _DiscoverState();
}
class _DiscoverState extends State<Discover> {
@override
Widget build(BuildContext context) {
return SingleChildScrollView(
scrollDirection: Axis.vertical,
