Not able to get SHA-1 key for flutter app

Question

I am developing a flutter app and want to use google sign in, for that, I require I need my apps SHA-1 keys.

How to get keys is explained here

But when I run the command ./gradlew signingReport

I am getting error:-

    Starting a Gradle Daemon, 2 stopped Daemons could not be reused, use --status for details

    FAILURE: Build failed with an exception.

    * What went wrong:
    Unable to start the daemon process.
    This problem might be caused by incorrect configuration of the daemon.
    For example, an unrecognized jvm option is used.
    Please refer to the User Manual chapter on the daemon at https://docs.gradle.org/5.6.2/userguide/gradle_daemon.html
    Process command line: C:\Program Files (x86)\Java\jre1.8.0_241\bin\java.exe -Xmx1536M -Dfile.encoding=windows-1252 -Duser.country=US -Duser.language=en -Duser.variant -cp E:\Users\rasku\.gradle\wrapper\dists\gradle-5.6.2-all\9st6wgf78h16so49nn74lgtbb\gradle-5.6.2\lib\gradle-launcher-5.6.2.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 5.6.2
    Please read the following process output to find out more:

To get the debug certificate fingerprint:

for Linux/mac open a terminal and run

keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

for windows

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