DI for IFirebasePushNotification in Blazor

[konrad79]

I've a Blazor Hybrid App - and want to use the plugin.
But how is this done with the dependency injection?

I inject the
@inject IFirebasePushNotification firebasePushNotification
in my Index.razor.
But do I have to do more than the
.UseFirebasePushNotifications()
in the MauiProgram?

The code builds but on startup I get (of course) the error:

"Cannot provide a value for property 'firebasePushNotification' on type 'BalzorHybridFirebaseTest2.Pages.Index'. There is no registered service of type 'Plugin.FirebasePushNotifications.IFirebasePushNotification'.

Unfortunately, I have never used blazer. UseFirebasePushNotifications not only registers required services, it also configures them. So maybe you habe to do something similar to what is done in UseFirebasePushNotifications method.

Thanks for the fast response.

I struggled several times about functions and properties not named exactly as in the documentation ... e.g.:

.UseFirebasePushNotifications(
o =>
{
    o.AutoInit = true;
})

instead of AutoInitEnabled
Where there major changes in the past? Using nuget version 1.0.26 of Plugin.FirebasePushNotifications

And even if I got the DI to work, when I call RegisterForPushNotifications() I get the error

Default FirebaseApp is not initialized in this process com.companyname.balzorhybridfirebasetest2. Make sure to call FirebaseApp.initializeApp(Context) first
which perhaps indicates that the AutoInit is not doing what it should? The google-services.json is in the path Platforms\Android\Resources as in the documentation, if that is important.

Version 1.x of the nuget was a clone of the old, unmaintained plugin. 2.x is a complete refactoring and it is not yet finished. There was/is a lot of static, untestable code in the old 1.x code base. The documentation you found is probably from the old/unmaintained plugin — I have nothing to do with this old plugin and the latest code (develop branch) does no longer correspond to it.

My goal was to create a .NET MAUI Android/iOS plugin for Firebase push notification for one of my apps. Everything else is optional. If you need enhancements, bug fixes or support, its all based on best effort. I can also offer commercial support, if you need help immediately 👍🏻
