我在应用栏中有一个抽屉，需要将它显示在底部导航栏上，但不能将两者放在同一个视图中，我不知道如何做到这一点。 This is what it looks like now 和 this is what it needs to look like.
这是appbar所在视图的一部分代码
class ContactsPage extends StatefulWidget {
final String title;
final String token;
final String qr;
String code;
final String name;
ContactsPage({this.name, this.token, this.qr, this.code, Key key, this.title})
: super(key: key);
@override
_ContactsPageState createState() => _ContactsPageState();
}
class _ContactsPageState extends State<ContactsPage> {
final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
List<Contact> contactList;
bool showHorizontalBar = false;
bool ready = false;
@override
void initState() {
super.initState();
var userService = new UserService();
userService.getContacts(widget.token).then((value) => {
print(value),
if (value == '0')
{
Navigator.pushReplacement(
context, MaterialPageRoute(builder: (context) => LoginPage()))
}
else if (value == '3')
{
Navigator.pushReplacement(
context, MaterialPageRoute(builder: (context) => LoginPage()))
}
else
{
setState(() {
contactList = value;
ready = true;
})
},
print(contactList),
});
}
void showMessage(String message, [MaterialColor color = Colors.red]) {
_scaffoldKey.currentState..removeCurrentSnackBar();
_scaffoldKey.currentState.showSnackBar(
new SnackBar(backgroundColor: color, content: new Text(message)));
}
_navigateAndDisplaySelection(BuildContext context) async {
final result = await Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Scanner(
qr: widget.qr,
token: widget.token,
)),
);
if (result != null) {
showMessage('$result', Colors.red);
}
}
Widget _addPerson() {
return FloatingActionButton(
onPressed: () {
_navigateAndDisplaySelection(context);
},
child: Icon(Icons.group_add),
backgroundColor: Color(0xff83bb37),
);
}
Widget buildMenuIcon() {
return IconButton(
icon: Icon(showHorizontalBar ? Icons.close : Icons.more_horiz),
onPressed: () {
setState(() {
showHorizontalBar = !showHorizontalBar;
});
},
);
}
Widget _simplePopup() => PopupMenuButton<int>(
itemBuilder: (context) => [
PopupMenuItem(
child: Row(
children: <Widget>[

Widget _card(String first_name, String last_name, String email) {
return Card(

}
Widget textContainer(String string, Color color) {
return new Container(

Widget _titulo() {
return new Container(

Expanded(

Expanded(

? ListView(

.map(
(Contact contact) => _card("${contact.first_name}",
"${contact.last_name}", "${contact.email}"),

.toList())
: Center(
child: Image.asset(

height: 125.0,
width: 125.0,
),
),
),
),
]),
floatingActionButton: _addPerson(),
);
}
}
这就是底部导航菜单的位置
class HomePage extends StatefulWidget {
HomePage({
this.token,
this.code,
Key key,
}) : super(key: key);
final String token;
final String code;
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
String currentPage = 'contacts';
changePage(String pageName) {
setState(() {
currentPage = pageName;
});
}
@override
Widget build(BuildContext context) {
final Map<String, Widget> pageView = <String, Widget>{
"contacts": ContactsPage(
code: widget.code,
token: widget.token,
),
"profile": ProfilePage(
token: widget.token,
),
};
return Scaffold(
body: pageView[currentPage],
bottomNavigationBar: new BottomNavigationDot(
paddingBottomCircle: 21,
color: Colors.black.withOpacity(0.5),
backgroundColor: Colors.white,
activeColor: Colors.black,
items: [
new BottomNavigationDotItem(
icon: Icons.home,
onTap: () {
changePage("contacts");
}),
new BottomNavigationDotItem(icon: Icons.brush, onTap: () {}),
new BottomNavigationDotItem(icon: Icons.notifications, onTap: () {}),
new BottomNavigationDotItem(icon: Icons.favorite, onTap: () {}),
new BottomNavigationDotItem(
icon: Icons.person,
onTap: () {
changePage("profile");
}),
],
milliseconds: 400,
),
);
}
}
编辑： 我曾考虑将 de appbar 放在与底部导航栏相同的级别，但我需要根据视图在 appbar 上放置不同的选项，所以我考虑使用不同的 appbar，这就是为什么我希望它与视图处于同一级别.
