Question

我不熟悉应用开发。获得了flutter项目的移交并尝试运行，但是通过终端命令获取Build Failed Exception。

flutter run -t lib/main_prod.dart

在终端中找到这些错误

尝试使用iOS和Android模拟器以及物理设备，但未成功我现在该怎么办？对不起，英语语法错误

Answer 1

这是 Firebase 配置的项目。

这个错误是因为 firebase firebase 的一些配置错误。错误是由于生成的密钥库造成的。

您应该会看到您的 firebase 控制台项目和应用的配置，并通过运行以下命令重新生成 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 查看您的密钥。
将这些键复制并粘贴到 firebase 项目应用中。

第二种解决方案是

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”文件并将其粘贴到您的应用文件夹中的项目“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。
