The configuration variable values are not overriding

Hi Team,

I am facing an issue, with overriding configuration values, actually I am using Google login plugin inside plugin, there is some dummy value for reverse client id variable . And I am taking dependency of this plugin into my application, so inside my application under extensibility configuration. I have overriding the reverse client id variable value again. But these value is not getting overriding,in the build files I am creating(Ipa & apk)

So my build file is having the value which is declared in the plugin. Not having the value which I have overriding in the application level.

Did anyone face this issue earlier, so anyone having solution or workaround for this issue. Please let me know

Regards,

Koushik.
