Flutter 運行時 Flutter App Build 失敗

Question

我是 Flutter 應用程序開發的新手。 交接了flutter項目並嘗試運行，但通過終端命令獲得Build Failed Exception。

flutter run -t lib/main_prod.dart

在終端中遇到這些錯誤

在上面的代碼構建文件'/Users/ashishsciit/Desktop/Ashish/onfees/edflylearnGit/android/app/build.gradle' line: 62 points to

storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null

嘗試使用 iOS 和 Android 模擬器以及物理設備，但沒有成功我現在該怎么辦？ 抱歉任何英語語法錯誤

Answer 1

它是 Firebase 配置的項目。

這個錯誤是因為 firebase firebase 的一些配置錯誤。 該錯誤是由於生成的密鑰庫造成的。

您應該會看到您的 firebase 控制台項目和應用程序的配置，並通過運行以下命令重新生成 SHA 指紋：

• keytool -genkey -v -keystore c:\\Users\\USER_NAME\\key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key
• 然后運行keytool -list -v -keystore debug.keystore -alias androiddebugkey來查看你的密鑰。
• 將這些鍵復制並粘貼到 firebase 項目應用程序中。

第二個解決方案是

• 查看 android/key.properties 中是否存在 key.properties 文件。
• 通過在命令提示符下運行以下命令，檢查生成的密鑰是否與此文件中提到的密鑰匹配。
• 運行keytool -list -v -keystore debug.keystore -alias androiddebugkey查看您的密鑰。
• 將相同的密鑰復制到您的 firebase 項目並下載“google-services.json”文件並將其粘貼到項目中的“C:\\Users\\USERNAME\\AndroidStudioProjects\\PROJECT_NAME\\android\\app\\google-services.json”。
• 運行flutter clean
• 通過運行pub get再次獲取所有依賴項。

您的問題很可能會得到解決。
