Firebase Messaging Error(Android only) - Fatal Exception on new Push Notification

We are currently using flutter to develop an app that receives push notifications. Everything worked fine until we did the last Flutter update and now we get a Fatal Exception inside Firebase - FlutterFirebaseMessagingService on Android only.

I couldn't find anything about this on the flutter git so it might be an android problem.

This happens the moment when the app gets a new Notification using Firebase functions and Firebase Messaging. Sample Data we use:

{
  notification: {
        title: „hello",
        body: „You got a new Message"
    },
    data: {
        click_action: "FLUTTER_NOTIFICATION_CLICK",
        additional: additional, // some integer values
        message: messageText // Same as message body above
    },
    apns: {
        payload: {
            aps: {
                badge: count,
            },
        },
    },
    token: deviceToken //this is a correct device id
}


admin.messaging().send(message)

Does anyone already have experience with this error or has an idea how to solve it ?

Edit: android/app/build.gradle:

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

the error message hints for iid; the instance ID service. this might be provided by firebase-core; while it could also be incompatible versions, which occassionaly lead to unknown methods and fields.

try to update:

classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.2.1'

to the current versions:

classpath 'com.android.tools.build:gradle:3.2.0'
classpath 'com.google.gms:google-services:4.1.0'

the firebase-perf plugin has to be at the top, not the bottom:

apply plugin: 'com.android.application'
apply plugin: 'com.google.firebase.firebase-perf'

also the library is outdated (possibly might require firebase-core):

implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-perf:16.1.2'

while I really wonder, why there is no dependency for FCM (as one would expect it):

implementation 'com.google.firebase:firebase-messaging:17.3.3'

once targeting API level 28, it is also suggested to setup a notification channel:

<meta-data
    android:name="com.google.firebase.messaging.default_notification_channel_id"
    android:value="@string/default_notification_channel_id" />

... the support libraries would be at version 28.0.0 currently.

remark: the invalid JSON syntax might (most likely) come from posting it wrongfully - otherwise other platforms would not function either; I've just added an explanation what is wrong with it and removed the hard-coded values. the stack-trace tells a whole other story, not hinting for any invalid syntax.
