Target class [firebase.messaging] does not exist.

Hi, I'm trying to send a push notification to a device but cannot seem to make it work, added this package today and followed the docs but I must be missing something. Little help would be appreciated. This is what I have so far:

You don’t need to instantiate the factory or anything, app('firebase.messaging') is enough to retrieve the fully configured messaging component.

You showed code, but what‘s the problem? 😅

[enefeka]

Hey, thanks for the quick answer! Problem is I get this error:

Target class [firebase.messaging] does not exist.

[jeromegamez]

Ah, missed the title 😅

Hm, strange. Have you set the FIREBASE_CREDENTIALS variable in your .env file? And could you please share the output of composer show | grep kreait?

[jeromegamez]

If you prefer to use an array instead of a credentials file, you could publish the package configuration and use the array as a value for the credentials.file key (the line where it reads the environment variable by default)

[enefeka]

Yep I do have the credentials set. This is the output of compose show | grep kreait

From what I can see, this does indeed look alright dependency-wise 🤔

If Laravel can‘t resolve the firebase.messaging Service (it tries to interpret it as a class name, not as the service name), perhaps the ServiceProvider of the package has not been auto-discovered...

If you do a composer dump-autoload, you should see a Discovered package: kreait/laravel-firebase line. If you don‘t, are you on... wait a minute! According to your composer show output, you haven‘t installed the package 😅

(I‘m writing this all on the phone, that‘s why you are receiving my thoughts and findings unfiltered 🙈)

Thanks man, I am as stupid as it gets. I could swear I installed it, like I can see myself having done it. Must've done it for another project, or confinement has finally destroyed my brain.

Anyways, thanks again for your help, is working now!

[jeromegamez]

I'm glad we figured it out together 🌺🥳

Hi, I was having this same error, I read all your comment but I thing I have all the setup config good.

But I have continue getting the error: Class firebase.messaging does not exist

I'm using lumen with the package Kreit.

[jeromegamez]

@juanzeta33 Did you add

$app->register(Kreait\Laravel\Firebase\ServiceProvider::class);

to your bootstrap/app.php file?

[juanzeta33]

Hi, thanks for the quick answer.

Yep, I have done that.

I follow all the step (I think so) describe in the official documentation.

1. Add the json file and the FIREBASE_CREDENTIALS in the env
2. Add the 4 package that install from Kreait (clock, firebase-php, firebase-tokens and laravel-firebase)
3. Call the Facades in the page that I'm trying to use the messaging.
4. Call the $messaging = app('firebase.messaging'); for send the push notifications
5. add the $app->register(Kreait\Laravel\Firebase\ServiceProvider::class); in the app.php

But continue having the error :(

[juanzeta33]

Hi,

Forget everything, I just forget to updated the app.php file in my dev server.

Sorry.

What worked for me is updating packages.php & services.php in bootstrap/cache folder
