我用 Flutter 开发了一个应用程序，目前已在 App Store 上架，但是，一个多星期以来，我一直在尝试提交应用程序更新，并不断收到审核团队的回复：

We were unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.
Review device details: 
- Device type: iPad
- OS version: iOS 14.6

我尝试了很多方法来解决这个问题：将 Xcode pod 设置更新为推荐值、删除文件夹并再次进行 git 克隆、重新启动 mac 并重新提交 4 次，但均无济于事。

这是他们发给我的崩溃日志：

当我切换应用程序的主题时，我试图使谷歌地图成为我的应用程序更新样式。

目前，我正在使用“provider”包来切换主题，它工作正常，但是，地图不会重建，这意味着样式不会改变。

我尝试制作一个应用程序构建器类并将页面包装在其中，然后在更改主题（按下按钮时）时重建构建器，但这不起作用。

以下是当我按下按钮切换主题时发生的代码

onPressed: () {
        _themeChanger.setTheme(
          Theme.of(context).brightness == Brightness.dark
              ? appTheme.lightTheme()
              : appTheme.darkTheme(),
        );
        AppBuilder.of(context).rebuild();
      },

以下是我正在尝试更新的地图页面

Future<void> onMapCreated(GoogleMapController _mapController) async {
mapController = _mapController;

Theme.of(context).brightness == Brightness.dark
    ? await mapController.setMapStyle(

预先感谢您的帮助。

 from newsapi.sources import Sources
 import json
 api_key ='*******************'
 s = Sources(API_KEY=api_key)

他们输入他们想要的新闻类别

 wanted = input('> ')
 source_list = s.get(category=wanted, language='en')

 index = 0
 sources = []

获取 source_list["sources"] 中 source 的来源：

     data = json.dumps(source_list)
     data = json.loads(data)

     source = (data["sources"][index]["url"])
     sources.append(source)
     index += 1


 from newspaper import Article

 i = len(sources) - 1

循环遍历源列表并打印源中源的文章：

     url_ = sources[i]

     a = Article[url_]  
     print(a)

     i -= 1

得到错误 'type' object is not subscriptable on the linea = Article[url_]已经研究过，但在我的情况下仍然不明白为什么。
