Applying Firebase configuration in MobileMessaging Flutter plugin

---

This documentation refers to the plugin versions 6.0.0 onwards and Gradle's Plugin DSL approach. For older plugin versions and imperative apply script method, see this document.

---

MobileMessaging Flutter plugin supports following ways of applying Firebase configuration:

1. [Preferable] Using Firebase configuration file (google-services.json)
2. Adding key/values from google-services.json to resource strings
3. Providing FirebaseOptions object to InfobipMobilemessaging.init method

Notice:

If you want to switch between types of configuration clean your project first, otherwise you can receive "Duplicate resources" errors.

[Preferable] Using Firebase configuration file (google-services.json)

1. Add "com.google.gms:google-services" in android/settings.gradle file:

plugins {
    ...
    id "com.google.gms.google-services" version "4.3.10" apply false
}

2. Add "com.google.gms:google-services" to plugins section at the end of android/app/build.gradle file to apply Google Services Gradle Plugin:

plugins {
    ...
    id "com.google.gms.google-services"
}

3. Setup Firebase for your project if it's not yet and add Firebase configuration file (google-services.json) to the app as described in Firebase documentation. Usually it needs to be added into android/app folder.

Adding key/values from google-services.json to resource strings

Add key/values from google-services.json to resource strings (app/src/main/res/values/strings.xml). Documentation of the Google Services Gradle Plugin gives the details of how to get these values from google-services.json file.

<resources>
    ...
    <! -- Required -->
    <string name="google_app_id" translatable="false">1:1035469437089:android:73a4fb8297b2cd4f</string>
    <string name="google_api_key" translatable="false">AIzbSyCILMsOuUKwN3qhtxrPq7FFemDJUAXTyZ8</string>
    <string name="project_id" translatable="false">mydemoapp</string>

    <! -- Optional -->
    <string name="gcm_defaultSenderId" translatable="false">1035469437089</string>
    <string name="default_web_client_id" translatable="false">337894902146-e4uksm38sne0bqrj6uvkbo4oiu4hvigl.apps.googleusercontent.com</string>
    <string name="ga_trackingId" translatable="false">UA-65557217-3</string>
    <string name="firebase_database_url" translatable="false">https://example-url.firebaseio.com</string>
    <string name="google_crash_reporting_api_key" translatable="false">AIzbSyCILMsOuUKwN3qhtxrPq7FFemDJUAXTyZ8</string>

</resources>

Notice:

id "com.google.gms.google-services" line should be removed from the android/app/build.gradle file, if it was added

Providing FirebaseOptions object to InfobipMobilemessaging.init method

Documentation of the Google Services Gradle Plugin gives the details of how to get these values from google-services.json file.

        await InfobipMobilemessaging.init(
          Configuration(
            applicationCode: "Your Application Code",
            inAppChatEnabled: true,
            defaultMessageStorage: true,
            androidSettings: AndroidSettings(
              firebaseOptions: FirebaseOptions(
                  apiKey: "Some-API-Key",
                  applicationId: "1:1234567890:android:abc123",
                  projectId: "project-123ab"),
            ),
            iosSettings: IOSSettings(
                notificationTypes: ["alert", "badge", "sound"],
                forceCleanup: false,
                logging: true),
          ),
        );

Notice:

id "com.google.gms.google-services" line should be removed from the android/app/build.gradle file, if it was added
