Firebase 自助登录问题

Question

I am building an android based mobile application using flutter. When I want to add firebase to my app, I am facing an issue on Debug signing certificate SHA-1 . I need to enter this command keytool -list -v \-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore . When I enter this command in my vscode terminal as I am building using the IDE, I get this error message.

Error message: -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.

I am not sure why this error message occurs and I am quite new to flutter and firebase. Still in the learning process. Can you help to tell which part I am doing wrong and how to solve it?

Answer 1

I'm not a Flutter programmer, but I believe that this was already asked and answered here .

If it is, please remember to search in stack overflow the non-case-specific part of the error, to improve your chances of finding help, without needing to ask a question and wait for an answer. Good Luck!

I don't have the ability to mark as a duplicate, but this appears to be a duplicate of this question: The term alias is not recognized

According to the existing Solution-marked answer, you need to run the following command in full: keytool -list -v -keystore %USERPROFILE%\.android\debug.keystore -alias androiddebugkey -storepass <store_password> -keypass <key_password> (Where store_password and key_password default to android).
