Hello currently i am on apps.ionic.io free plan. i created a project everything works fine i added cordova-plugin-fcm in my project it tells to add google-services.json file on project root i added the file then i added couple of code related to FCM plugin and the project was serve successfully on web browser then i decided to got .apk for that project so i give ionic package command but in cloud the ionic throws an error "you are using plugin fcm which requires google-services.json file in your root
create your google-services.json file in firebase by using proper package name. Once the google-services.json file is created, download it and paste it into the âplatform->androidâ path.
