未處理的異常：MissingPluginException 錯誤 flutter

Question

我正在使用 permission_handler package 並收到此錯誤。

    [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method checkServiceStatus on channel flutter.baseflow.com/permissions/methods)
E/flutter (17382): #0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:165:7)
E/flutter (17382): <asynchronous suspension>
E/flutter (17382): #1      MethodChannelPermissionHandler.checkServiceStatus (package:permission_handler_platform_interface/src/method_channel/method_channel_permission_handler.dart:45:20)
E/flutter (17382): <asynchronous suspension>
E/flutter (17382): #2      FutureServiceStatusGetters.isEnabled (package:permission_handler_platform_interface/src/service_status.dart:61:40)

尷尬的部分是當我的朋友編譯並運行相同的代碼時，它運行良好。 我不知道該怎么辦。 我嘗試了互聯網上的每一個解決方案，但還沒有運氣。可能是什么問題？

Answer 1

嘗試清理 flutter，刪除 pubspec.lock 文件。

然后運行flutter pub get然后flutter run 。

Answer 2

如果它發生在 android 上試試這樣......

也檢查這個類似的問題是here 。 也許你會找到一些想法。

1. 將以下內容添加到您的“gradle.properties”文件中：

   android.useAndroidX=true

   android.enableJetifier=true

2. 確保將“android/app/build.gradle”文件中的 compileSdkVersion 設置為 31：

   android { compileSdkVersion 31 ... }

Answer 3

我解決了這個問題；

刪除android studio重新下載。同時刪除flutter文件重新下載。
