User receives notifications and clicks on it
There can be two scenarios here:-

  1. App in foreground ie. being used by user
    Notification will open registered screen.

GotData even will be raised upon screen initialization if screen opened through notification.

You can obtain data from RetrieveData method also.

  1. App not opened by user.
    Notification click will open registered screen (or Screen1 if not set) and GotData event will be raised. If no screen is registered then Screen where FCM extension has been initialized is automatically registered.

ChangeLog Version 1.1

  • Added ClearNotification block

  • Added feature to store all messages in Tiny DB with tag as timestamp
    Set namespace to FCM_DATA to retrieve those messages

  • Fixed inconsistency in SendNotificationToTokens and SendMessageToTokens blocks

  • Some internal changes to make future improvements easier to adapt

ChangeLog Version 1.2

  • Removed SoundOn property

  • Custom Notification sound feature
    Beta tested by @Franklin_Lopez

To send a notification with custom sound, upload mp3 file to assets and send payload like this:

{\"notification\": {\"body\": \"this is a body\", \"default\": \"this is a title\", \"sound2\":\"default\",\"icon\":\"https://res.cloudinary.com/andromedaviewflyvipul/image/upload/c_scale,h_20,w_20/v1571472765/ktvu4bapylsvnykoyhdm.png\"},\n    \"priority\": \"high\",\n    \"data\": {\n      \"click_action\": \"FCM_MESSAGE\",\n      \"id\": \"1\",\n      \"status\": \"done\"\n    },\n    \"to\": \"/topics/FCMTEST\""}

Value for sound2 key can be file name ( like test for test.mp3 ) or none for no sound or default for default notification sound.
This key must be present in notification payload otherwise no sound will be played.

Aix size is 500 kb now.

ChangeLog Version 1.4

  • New Blocks
    You can retrieve messages which were received when app was not running. Returns Dictionary where timestamp is key and value is message content.

  • Behavior Changes
    i) Clicking fcm notification when app is in foreground will open registered screen (or Screen1 if not set), but previous instance of Screen will be created if that screen is already running instead will be resumed.
    ii) Now notifications received in background also use small icon. (Earlier app icon was shown)

  • Internal Changes
    Important changes to adapt HTTP v1 Api for sending notifications

  • Aix size reduced to 468 kb

Notification (and Message) sending API has been removed (deprecated on June 20, 2023 ) by Firebase and can stop working anytime.
A separate extension for sending notifications will be released soon and it will be a PAID extension.

Receiving notifications will continue working without any issue.

Recommended to use.
