颤振运行时颤振应用程序构建失败

Question

我是 Flutter 应用开发的新手。拿到了flutter项目的交接，尝试运行，终端命令出现Build Failed Exception。

flutter run -t lib/main_prod.dart

在终端中遇到这些错误

在上面的代码构建文件'/Users/ashishsciit/Desktop/Ashish/onfees/edflylearnGit/android/app/build.gradle'行：62点到

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

尝试了 iOS 和 Android 模拟器以及物理设备，但没有成功 我现在该怎么办 ？ 如有英文语法错误，请见谅

Answer 1

这是 Firebase 配置的项目。

此错误是由于 firebase firebase 的一些配置错误。错误是由于生成的密钥库造成的。

您应该会看到 Firebase 控制台项目和应用的配置，并通过运行重新生成 SHA 指纹：

• keytool -genkey -v -keystore c:\Users\USER_NAME\key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias key
• 然后运行 ​​keytool -list -v -keystore debug.keystore -alias androiddebugkey 以查看您的密钥。
• 将这些密钥复制并粘贴到 Firebase 项目应用中。

第二个解决方案是

• 查看 android/key.properties 中是否存在 key.properties 文件。
• 通过在命令提示符下运行以下命令检查生成的密钥是否与此文件中提到的密钥匹配。
• 运行 keytool -list -v -keystore debug.keystore -alias androiddebugkey 以查看您的密钥。
• 将相同的密钥复制到您的 firebase 项目并下载“google-services.json”文件并将其粘贴到项目中的应用程序文件夹“C:\Users\USERNAME\AndroidStudioProjects\PROJECT_NAME\android\app\google-services. json”。
• 运行flutter clean
• 通过运行pub get 再次获取所有依赖项。

您的问题很可能会得到解决。
