我在应用程序中使用了GoogleMaps小部件，注意到每当我最小化应用程序并重新打开它时，它就会崩溃。因此，我在终端中进行了详细的运行，并在应用程序退出前获得了以下日志。

现在，我在iOS模拟器和真正的Android设备上运行了完全相同的代码，没有出现崩溃。造成这种情况的原因是什么？发布应用程序后，我如何确保它不会在真实设备上崩溃
代码到MapScreen可以在这里查看
颤振-版本
Flutter 1.22.4 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 1aafb3a8b9 (3 days ago) • 2020-11-13 09:59:28 -0800

我建议您使用真实的设备进行尝试。
你可以将你的真实设备连接到你的计算机上，并使用flutter run -d {device Name/Id}进行构建
设备名称/id可以通过命令flutter devices找到
模拟器并不完美，一些功能可能会导致崩溃(例如，在iOS设备上访问图库会导致Flutter崩溃(。
