如何修復錯誤：“vs代碼上的資源mipmap/ic_啟動器（又名com.example.MyAppName:mipmap/ic_launcher)而不是found."”

我需要一些幫助來解決我的聊天應用程序面臨的問題。一切都很順利，但我把這個項目擱置了months.And當我再次開始工作時，我不得不升級所有的包和flutter本身，以便它能工作。但我不知道為什么會發生這種錯誤，這里是完整的錯誤：

任務':app:processDebugResources'.執行失敗>執行com.android.build.gradle.internal.tasks.Workers$ActionFacadeAndroid資源鏈接失敗D:\MyAppName2.0\myappname\build\app\intermediates\packaged_manifests\debug\AndroidManifest.xml:19:AAPT:錯誤：資源mipmap/ic_launcher（又名com.example.MyAppName:mipmap/ic_launcher）未找到。

我沒有試圖改變圖標的任何名稱或其他任何東西，所以如果有人能幫助我，那將是非常棒的。這是我的pubspec.yaml文件和AndroidManifest.xml：

如果您需要查看其他文件，這絕對沒有問題！謝謝
