У меня есть два файла дротика: Home.dart и menuUser.dart. Я следовал некоторому руководству по разработке своих приложений. Моя проблема сейчас в том, что я не знаю, как разместить панель поиска или контейнер в моем Home.dart, потому что у меня уже есть appBar внутри моего menuUser.dart. Я выяснил, что если я помещу appBar в свой Home.dart, мои приложения будут иметь двойную панель вкладок вверху.
Вот мой menuUser.dart
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'package:myapp/model/api.dart';
import 'package:myapp/view/home.dart';
import 'package:myapp/view/budget.dart';
import 'package:myapp/view/locationMap.dart';
import 'package:myapp/view/profile.dart';
import 'package:shared_preferences/shared_preferences.dart';
class MenuUsers extends StatefulWidget {
final VoidCallback signOut;
MenuUsers(this.signOut);
@override
_MenuUsersState createState() => _MenuUsersState();
}
class _MenuUsersState extends State<MenuUsers> {
signOut(){
setState((){
widget.signOut();
});
}
String name = "";
TabController tabController;
getPref()async{
SharedPreferences preferences = await SharedPreferences.getInstance();
setState(() {
name = preferences.getString("name");
});
}
@override
void initState() {
// TODO: implement initState
super.initState();
getPref();
}
@override
Widget build(BuildContext context) {
return DefaultTabController(
length: 4,
child: Scaffold(
appBar: AppBar(
backgroundColor: Colors.pink,
actions: <Widget>[
IconButton(
onPressed: (){
signOut();
},
icon: Icon(Icons.lock_open),
)
],
),
body: TabBarView(
children: <Widget>[
Home(),
Budget(),
LocationMap(),
Profile(),
],
),
bottomNavigationBar: TabBar(
labelColor: Colors.pink,
unselectedLabelColor: Colors.grey,
indicator: UnderlineTabIndicator(
borderSide: BorderSide(
style: BorderStyle.none
)
),
tabs: <Widget>[
Tab(
icon: Icon(Icons.home),
text: "Home",
),
Tab(
icon: Icon(Icons.shopping_basket),
text: "Budget",
),
Tab(
icon: Icon(Icons.map),
text: "Location",
),
Tab(
icon: Icon(Icons.person),
text: "Profile",
)
],
),
),
);
}
}
, а вот my Home.dart

Вот моя страница пользователя меню, и я хочу разместить панель поиска вверху страницы, вероятно, рядом с кнопкой выхода:
