在为 firebase 生成 SHA1 密钥时无法识别术语“-alias”

问：

在为 firebase 生成 SHA1 密钥时，我正在使用此命令

keytool -list -v \
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

然后我收到这个错误

-alias : The term '-alias' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is 
correct and try again.

+ -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystor ...
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (-alias:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

有人向我建议了这个命令

keytool -list -v -alias androiddebugkey -keystore "%USERPROFILE%/.android/debug.keystore"

现在我收到这个错误

keytool error: java.lang.Exception: Keystore file does not exist: %USERPROFILE%/.android/debug.keystore
java.lang.Exception: Keystore file does not exist: %USERPROFILE%/.android/debug.keystore

请帮助，或建议任何 Firebase 与 flutter 项目集成的教程视频

我正在尝试为与我的 flutter 项目的 Firebase 连接生成 SHA1 密钥，但我遇到了几个错误，我希望有人帮助我。
