The error is due to a mismatch between your app's package name (com.webkul.bagisto.mobikul) and the ones defined in the google-services.json file (bagisto).
To fix this, please add a new Android app in your Firebase project with the correct package name, then download and replace the existing google-services.json file in your project.

As a temporary workaround to get the project running for testing, you can change the applicationId and package name in your project to match the one used in the existing google-services.json (com.bagisto.test). Here are the steps:

Update applicationId in build.gradle:

defaultConfig {
applicationId "com.bagisto.test"
// keep the rest unchanged
}

Update package_name in google-services.json:

"package_name": "com.bagisto.test"

Clean and Rebuild the project and Let us know if you need any help.
