A bad client could register valid tokens of other users.

So far, I am using the plugin firebase_messaging with the following code: Message firebaseMessage = Message() ..to = token ..body = body ..title = title; firebaseCloudMessage.send(firebaseMessage); This allows me to send a notification to a selected user and display it on their home screen. The only problem is, it does not play a sound on iOS or give Apple Watch

问题 This question was originally referring to Google Cloud Messaging (GCM), but now it also applies to the new Firebase Cloud Messaging (FCM) that replaces GCM. I would like to know how to calculate the size of a GCM payload when it contains a "notification" dictionary. I have been trying the Google Cloud Messaging service for Android. Some parts of the documentation say you can send up to 4KB of data, and here it says "A notification message can have a maximum of 2kb payload". Doing some tests I
