Question

我在运行我的应用程序时遇到问题。重新启动，清洁等均无效。构建时出现错误：

E/flutter ( 6999): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: MissingPluginException(No implementation found for method getApplicationSupportDirectory on channel plugins.flutter.io/path_provider)
E/flutter ( 6999): #0      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:319:7)
E/flutter ( 6999): <asynchronous suspension>

E/flutter ( 6999): #7      loadFontIfNecessary (package:google_fonts/src/google_fonts_base.dart:165:18)
E/flutter ( 6999): <asynchronous sus

然后在应用中尝试登录后

I/flutter ( 6999): MissingPluginException(No implementation found for method getToken on channel plugins.flutter.io/firebase_messaging)

pubspec.yaml：

Flutter未处理的异常：path_provider和firebase_messaging的MissingPluginException
