Detailed Description

This item defines an optional custom account configuration to use for the Firebase items. Per default, the account configuration is included in google-services.json on Android and GoogleService-info.plist on iOS. If you only use one Firebase account, you do not need to instantiate FirebaseConfig manually. Simply add the config files to your project and start using FirebaseAuth and FirebaseDatabase.

Using FirebaseConfig, you can use multiple Firebase accounts from within one Felgo app. Create an instance of FirebaseConfig in QML and reference it with the properties FirebaseAuth::config and FirebaseDatabase::config.

Example usage:

 FirebaseAuth {
   id: customAuth

   //assign custom config values - override config from google-services.json / GoogleService-info.plist
   config: FirebaseConfig {
     //get these values from the firebase console
     projectId: "projectabc-1234"
     databaseUrl: "https://projectabc-1234.firebaseio.com/"

     //platform dependent - get these values from the google-services.json / GoogleService-info.plist
     apiKey:        Qt.platform.os === "android" ? "android-key"           : "ios-key"
     applicationId: Qt.platform.os === "android" ? "1:abcdef:android:1234" : "1:abcdef:ios:1234"
   }

   onFirebaseReady: loginUser("username", "pw")
 }

To be able to use database with authentication and custom Firebase account details, be sure to use the same FirebaseConfig instance for both these types, as in the following example.

 App {
   //this object can override the default firebase config when used in FirebaseAuth/Database
   FirebaseConfig {
     id: customConfig

     //get these values from the firebase console
     projectId: "projectabc-1234"
     databaseUrl: "https://projectabc-1234.firebaseio.com/"

     //platform dependent - get these values from the google-services.json / GoogleService-info.plist
     apiKey:        Qt.platform.os === "android" ? "android-key"           : "ios-key"
     applicationId: Qt.platform.os === "android" ? "1:abcdef:android:1234" : "1:abcdef:ios:1234"
   }

   FirebaseAuth {
     id: defaultAuth

     //config not assigned - use default auth with values from google-services.json / GoogleService-info.plist

     onFirebaseReady: loginUser("username", "pw")
   }

   FirebaseAuth {
     id: customAuth

     //assign custom config values
     config: customConfig

     onFirebaseReady: loginUser("username", "pw")
   }

   FirebaseDatabase {
     id: defaultDb

     //config not assigned - use default DB with values from google-services.json / GoogleService-info.plist

     onFirebaseReady: getValue("public/myDbValue")
   }

   FirebaseDatabase {
     id: customDb

     //assign custom config values
     config: customConfig

     onFirebaseReady: getValue("public/myDbValue")
   }

   //use auth and database in app...
 }
