阅读页整合问题..求帮助

[hajiuxbz]

我只想使用作者的阅读页..开始整合的挺正常 后来不知道改了哪一直报这个错误
但是好像不影响正常使用 目前只能确定是NovelReaderContentModel parseChapterContent的问题
但是具体是哪就不知道了也没有更详细的错误提示了...

E/FlutterIsolate(21936): IllegalStateException: registrar.activity() must not be null
E/FlutterIsolate(21936): It is possible the default GeneratedPluginRegistrant is attempting to register
E/FlutterIsolate(21936): a plugin that uses registrar.activity() or a similar method. Flutter Isolates have no
E/FlutterIsolate(21936): access to the activity() from the registrant. If the activity is being use to register
E/FlutterIsolate(21936): a method or event channel, have the plugin use registrar.context() instead. Alternatively
E/FlutterIsolate(21936): use a custom registrant for isolates, that only registers plugins that the isolate needs
E/FlutterIsolate(21936): to use.
