[woprandi]

Describe the bug
Hi,

After follow the README, I got build errors (new flutter app) :

Launching lib/main.dart on AOSP on IA Emulator in debug mode...
e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService, unresolved supertypes: com.google.firebase.messaging.FirebaseMessagingService

e: /home/william/Documents/test/android/app/src/main/kotlin/com/example/test/Application.kt: (16, 45): Type mismatch: inferred type is PluginRegistry but FlutterEngine was expected

 class Application: FlutterApplication(), PluginRegistrantCallback {
   override fun onCreate() {
     super.onCreate()
     FlutterFirebaseMessagingService.setPluginRegistrant(this)
   }

   override fun registerWith(registry: PluginRegistry) {
     GeneratedPluginRegistrant.registerWith(registry)
   }
 }

To Reproduce
Steps to reproduce the behavior:

1. Create Flutter app
2. Use firebase_messaging 0.6.7
3. Follow the documentation for Android

Expected behavior
No build problem

Additional context

[wooks186]

same here!

[hsangtini]

I fixed by replace

override fun registerWith(registry: PluginRegistry?) {
        registry?.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin");
    }

[harloom]

same here!

[arasu33]

I used firebase_messaging: ^6.0.8
Same Error

[zeienko-vitalii]

Same error

• Flutter version 1.12.13+hotfix.5 at /Users/user/Documents/Java/flutter
    • Framework revision 27321ebbad (32 hours ago), 2019-12-10 18:15:01 -0800
    • Engine revision 2994f7e1e6
    • Dart version 2.7.0

Firebase version:
firebase_messaging: ^6.0.8

[MapleNoise]

I downgrade firebase_messaging in my pubspec waiting fix error :
firebase_messaging: 6.0.3

[marinat]

Same error

[mhadaily]

same error and same environment
dart 2.7 and firebase_messaging: 6.0.8 and flutter 1.12.13+hotfix.5

Hi @woprandi
I see there's an open issue addressing the case you described.
Please follow up on that issue,
I'm closing the current one as duplicate.
If you disagree please write in the comments
and I will reopen it.
Thank you

[woprandi]

@iapicca And the code of the Application.java in the README is invalid

[xellDart]

same error

[mrifni]

I was able to get rid of the error by doing these below changes

in android/build.gradle
classpath 'com.google.gms:google-services:4.3.3'

in android/app/build.gradle
implementation "com.google.firebase:firebase-analytics:17.2.1" (you probably wont need this)
implementation "com.google.firebase:firebase-messaging:20.1.0"

[digarahayu]

@mrifni work perfectly

[woprandi]

Why add firebase-messaging dependency in the build.gradle since it wasn't necessary until now ?

[mrifni]

not sure, flutter docs doesnt cover adding of dependencies of firebase-messaging

[insinfo]

for me decided by doing this:

 class Application : FlutterApplication() , PluginRegistrantCallback {

   override fun onCreate() {
     super.onCreate();

in android/build.gradle
classpath 'com.google.gms:google-services:4.3.3'

in android/app/build.gradle
implementation "com.google.firebase:firebase-messaging:20.1.0"

Doing this solved it for me

[meidikawardana]

@insinfo your answer is too long. you should point out what you add / update on your code like what @mrifni did

[altafkhan8719]

I was able to get rid of the error by doing these below changes

in android/build.gradle
classpath 'com.google.gms:google-services:4.3.3'

in android/app/build.gradle
implementation "com.google.firebase:firebase-analytics:17.2.1" (you probably wont need this)
implementation "com.google.firebase:firebase-messaging:20.1.0"

Thanks
It Solve my Problem

Hi @woprandi
I see there's an open issue addressing the case you described.
Please follow up on that issue,
I'm closing the current one as duplicate.
If you disagree please write in the comments
and I will reopen it.
Thank you

@iapicca Please mention this https://github.com/FirebaseExtended/flutterfire/issues/1607#issuecomment-565793930 as the solution for this issue.
I surely believe #1606 is not the duplicate of #1607

This comment https://github.com/FirebaseExtended/flutterfire/issues/1607#issuecomment-565793930 has worked for several people:

• @altafkhan8719 https://github.com/FirebaseExtended/flutterfire/issues/1607#issuecomment-577028200
• @SEGVeenstra https://github.com/FirebaseExtended/flutterfire/issues/1607#issuecomment-569658215
• @digarahayu https://github.com/FirebaseExtended/flutterfire/issues/1607#issuecomment-565876176
• and at last, it worked for me as well

[JFernandoGomez]

for me decided by doing this:

Aplication.kt

```kotlin
package br.gov.rj.riodasostras.appsescverao

...

@insinfo what are we looking at here? what are your specific changes to the default steps provided by the documentation?

[iapicca]

Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so it's always better to open new issues and reference related issues.
