如何触发作为 PersistentTabView 屏幕列表 (PersistentTabView) 子项的特定 StatefulWidget 的 didChangeDependencies()

如何解决如何触发作为 PersistentTabView 屏幕列表 (PersistentTabView) 子项的特定 StatefulWidget 的 didChangeDependencies()

每次切换项目时触发 initState()、didChangeDependencies() 的过程是什么。

我在 Timeline() 上展示了一些广告，并且可以使用 provider 保存这些广告 (isSaved = true)。问题是，当我切换到 SavedAds() 时，它第一次向我显示正确的保存项目。但是，如果我转到 Timeline() 并保存更多内容，即使我使用提供程序收听保存的广告，SavedAds() 也不会更新。

我还注意到，每次切换到新的 Screen() 时，它都不会触发 initState()、didChangeDependencies()，当我切换到新的 Screen() 时，如何触发 initState()、didChangeDependencies()

我的主屏幕

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:persistent_bottom_nav_bar/persistent-tab-view.dart';
import 'package:women_home/GLOBALS.dart';
import 'package:women_home/screens/home/timeline.dart';
import 'package:women_home/screens/saved/savedAds.dart';

class HomeCore extends StatefulWidget {
  static const String id = "/homeCore";
  @override
  _HomeCoreState createState() => _HomeCoreState();
}

class _HomeCoreState extends State<HomeCore> {
  late PersistentTabController _controller;

  List<Widget> _buildScreens() {
    return [
      Timeline(),Container(),SavedAds(),];
  }

  List<PersistentBottomNavBarItem> _navBarsItems() {
    return [
      PersistentBottomNavBarItem(
        routeAndNavigatorSettings: RouteAndNavigatorSettings(),icon: Icon(CupertinoIcons.home),title: ("Home"),activeColorPrimary: CupertinoColors.activeBlue,inactiveColorPrimary: CupertinoColors.systemGrey,),PersistentBottomNavBarItem(
        icon: Icon(CupertinoIcons.bubble_left),title: ("Messages"),PersistentBottomNavBarItem(
        icon: Icon(CupertinoIcons.bell),title: ("Notifications"),PersistentBottomNavBarItem(
        icon: Icon(CupertinoIcons.heart),title: ("Saved"),PersistentBottomNavBarItem(
        icon: Icon(CupertinoIcons.person),title: ("Account"),];
  }

  @override
  void initState() {
    _controller = PersistentTabController(initialIndex: 0);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: GLOBALS.appBgColor,body: PersistentTabView(
        context,controller: _controller,screens: _buildScreens(),items: _navBarsItems(),confineInSafeArea: true,backgroundColor: Colors.white,// Default is Colors.white.
        handleAndroidBackButtonPress: true,// Default is true.
        resizeToAvoidBottomInset: true,// This needs to be true if you want to move up the screen when keyboard appears. Default is true.
        stateManagement: true,// Default is true.
        hideNavigationBarWhenKeyboardShows: true,// Recommended to set 'resizeToAvoidBottomInset' as true while using this argument. Default is true.
        decoration: NavBarDecoration(
          borderRadius: BorderRadius.circular(10.0),colorBehindNavBar: Colors.white,popAllScreensOnTapOfSelectedTab: true,popActionScreens: PopActionScreensType.all,itemAnimationProperties: ItemAnimationProperties(
          // Navigation Bar's items animation properties.
          duration: Duration(milliseconds: 200),curve: Curves.ease,screenTransitionAnimation: ScreenTransitionAnimation(
          // Screen transition animation on change of selected tab.
          animateTabTransition: true,duration: Duration(milliseconds: 200),navBarStyle: NavBarStyle.style9,// Choose the nav bar style with this property.
      ),);
  }
}

这里是 SavedAds()

class SavedAds extends StatefulWidget {
  @override
  _SavedAdsState createState() => _SavedAdsState();
}

class _SavedAdsState extends State<SavedAds> {
  late List<PropertyAd> _savedAds;
  @override
  void initState() {
    print("init fired");
    super.initState();
  }

  @override
  void didChangeDependencies() {
    print("fired");
    setState(() {});
    super.didChangeDependencies();
  }

  @override
  Widget build(BuildContext context) {
    _savedAds = Provider.of<PropertyAds>(context).getSavedAds();
    print("build fired");
    return Scaffold(
      backgroundColor: GLOBALS.appBgColor,body: Container(
        padding: EdgeInsets.all(20),child: ListView.builder(
          itemCount: _savedAds.length,itemBuilder: (context,int i) => ChangeNotifierProvider.value(
            value: _savedAds[i],child: SinglePropertyAd(),);
  }
}
