I/flutter (29003): FCM message sent successfully
D/FLTFireMsgReceiver(29003): broadcast received for message

[@CodeMender]

The firebase push notification is only shown for background notification for foreground notification you need to customize toast or alert.

where to get client_id and client_secret by using post man

[@CodeMender]

To obtain the client_id and client_secret:
Navigate to the Google Cloud Console, access the service account section, and generate a key. The JSON file will contain the necessary client_id and client_secret.
To get the bearer token in Postman follow these steps:
1. Utilize Google OAuth Playground to authorize API access by Entering your OAuth client ID and client secret (obtained from Google Cloud Console).
2. Specify your desired scopes for Firebase Cloud Messaging (FCM) by accessing this URL: www.googleapis.com/auth/firebase.messaging
3. Click on "Authorize APIs" and go through the authorization process.
Exchange the authorization code for tokens.
The access token serves as your Bearer token.

@@CodeMender how can I generate access token please, I already have my service key and json file

[@CodeMender]

Create Scopes for which you want to allow the authorization when using the access token. Create a client using your JSON file by HTTP package and use the googleapis package to get credentials by sending client, scopes and ServiceAccountCredentials from the json file. You will get accessToken in the credentials.
