Flutter 應用程序 apk 在手機上無法正常運行，但在模擬器上運行良好

Question

Flutter 應用程序 apk 在手機上無法正常運行，但在模擬器上運行良好。單擊按鈕將數據添加到 sqflite 數據庫不起作用或當我更改應用程序語言時。我已經嘗試了我在互聯網上找到的所有建議，但它仍然不起作用我不明白問題出在哪里。在模擬器中效果很好但是當我安裝 apk 並將其安裝在我的手機上時，它不起作用。 Flutter 運行-v

我剛剛收到上述錯誤。我創建了一個新項目，即使在 flutter 演示應用程序中也出現了該錯誤所以這不是我的代碼的錯誤。請幫助我，我已經處理了 3 天

Flutter build apk 出現此錯誤。

    FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:lintVitalRelease'.
> Could not resolve all artifacts for configuration ':app:debugRuntimeClasspath'.
   > Failed to transform libs.jar to match attributes {artifactType=processed-jar, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.
      > Execution failed for JetifyTransform: 

但是我沒有收到這些代碼的錯誤，但是 apk 不能正常工作。

flutter build apk --debug

flutter build apk --profile

flutter build apk --release

我不明白為什么會出現問題，但是我處理了它。我創建了一個不同名稱的新項目，並將舊項目的文件一個一個重建並復制了內容。我重新下載了所有包在新版本的依賴項下。最后我添加了互聯網權限androidManifest.xml ，即使我的應用程序沒有使用互聯網。 <uses-permission android:name="android.permission.INTERNET" />

此問題很可能在更新 Flutter 后發生。 更新 Flutter 后總是檢查
