Overview

The default provider uses Firebase on Android and APNs on iOS directly. No additional NuGet package is needed beyond Shiny.Push.

services.AddPush<MyPushDelegate>();

Firebase Messaging

Firebase Cloud Messaging can be used as a unified provider across both platforms.

NuGet: Shiny.Push.FirebaseMessaging

// Auto-config from google-services.json
services.AddPushFirebaseMessaging<MyPushDelegate>();

Note

On iOS, Firebase Messaging swizzles the APNs token and provides its own registration token. This is transparent — your OnNewToken delegate method receives the Firebase token.

Custom Provider

Create your own push provider by implementing IPushProvider.

public class MyPushProvider : IPushProvider
{
#if ANDROID
    public async Task<string> Register(string nativeToken)
    {
        // Register with your backend, return your provider token
        var providerToken = await MyBackend.RegisterToken(nativeToken);
        return providerToken;
    }
#elif IOS
    public async Task<string> Register(NSData nativeToken)
    {
        var tokenString = nativeToken.ToPushTokenString();
        var providerToken = await MyBackend.RegisterToken(tokenString);
        return providerToken;
    }
#elif WINDOWS
    public async Task<string> Register(string nativeToken)
    {
        // nativeToken is the WNS channel URI
        var providerToken = await MyBackend.RegisterToken(nativeToken);
        return providerToken;
    }
#endif

    public async Task UnRegister()
    {
        await MyBackend.UnregisterToken();
    }
}

Registration

Tag the provider with [Singleton] from Shiny.Extensions.DependencyInjection (or register it manually for every interface) and call AddGeneratedServices():

services.AddPush<MyPushDelegate>();
services.AddGeneratedServices(); // emits the registration for [Singleton] MyPushProvider

If you prefer explicit registration without the source generator:

services.AddSingleton<MyPushProvider>();
services.AddSingleton<IPushProvider>(sp => sp.GetRequiredService<MyPushProvider>());
