颤振插件抛出错误"Thread 1: EXC_BAD_ACCESS"在 iOS 上

Question

我一直在尝试使用插件" livecchat "在https://pub.dev/packages/livechatt我的Flutter应用程序中找到。我在Android版本中没有遇到任何问题，但在iOS版本中，它每次都以同样的方式失败。

我在我的pubspec.yaml中导入了包，就像我在其他插件中导入包一样。当从Android Studio在iOS模拟器中运行应用程序时，构建成功，但应用程序在启动后立即崩溃。当从Xcode运行应用程序时，构建成功，但应用程序在启动启动屏幕上冻结。

注意:目前，这个插件在iOS上的依赖有一个错误，所以那些测试它的人需要在livechatt.podspec中将目标操作系统从iOS 9.0更改为iOS 11.0，然后在项目的iOS目录下运行pod install来同步更改

然后Xcode显示以下错误:

我能有一些帮助诊断这个错误是在这些地方抛出的原因，为什么它只影响livechatt插件?谢谢你！
