    \title Firebase Push Notification Example
    \ingroup examples-qtcloudmessaging
    \brief Demonstrates Firebase Cloud Messaging support with Qt.

    \image pushnotification-example.png Screenshot of the example

    \e {Firebase Cloud Messaging (FCM)} is a messaging solution. It reliably
    delivers messages via the \e FCM servers. Using \e FCM, you can send
    notification messages to notify a client app that a new message is available
    to sync. To learn more, visit \l
    {https://firebase.google.com/docs/cloud-messaging}.

    This example demonstrates receiving push notifications from the \e {Firebase
    Console}, and then displays the content on the screen in JSON format. You
    can send push notifications to devices running this example by using the
    notifications composer in the \e {Firebase Console}. The fields such as \e
    message-text and \e custom-data are sent to this application in a payload
    composed of key/value pairs.

    To use this example, the user must install \e {Firebase SDK} to their
    environment. See https://firebase.google.com/docs/android/setup
    \note Set environment variable \e GOOGLE_FIREBASE_SDK to the root directory
    of \e {Firebase C++ SDK}.
    \note Download the registered \c google-service.json from the \e {Firebase
    Console} and save it as \c android-sources/google-services.json, replacing
    the sample file.
