### Set Up Auth State Listener

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/firebase-auth.md

Implement an asynchronous listener to react to changes in the user's authentication state. This is crucial for updating the UI or application logic based on whether a user is signed in or out.

```csharp
await MauiFIRAuth.SetAuthStateListenerAsync((user) => {
    if (user != null)
    {
        OnUserSignedIn(user);
    }
    else
    {
        OnUserSignedOut();
    }
});
```

--------------------------------

### Async/Await Generation for Callbacks

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/overview.md

Demonstrates how callback-based Objective-C methods are automatically converted to C# async methods for easier consumption.

```csharp
// Original definition with callback
[Export("getAppInstanceIdWithCompletion:")]
[Async]
void GetAppInstanceId(Action<NSString?> completion);

// Generated async method
Task<NSString> GetAppInstanceIdAsync();

// Usage
var id = await MauiFIRAnalytics.GetAppInstanceIdAsync();
```

--------------------------------

### Implementing Error Handling for Sign-In

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/overview.md

Implement robust error handling for authentication operations using a `try-catch` block. Log detailed error messages and display user-friendly alerts to inform the user about sign-in failures.

```csharp
try
{
    await MauiFIRAuth.SignInAsync(email, password);
}
catch (Exception ex)
{
    Debug.WriteLine($"Sign in failed: {ex.Message}");
    await DisplayAlert("Error", "Sign in failed", "OK");
}
```

--------------------------------

### Objective-C to C# Method Mapping

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/binding-template.md

Demonstrates how to map an Objective-C static method with parameters to its C# equivalent using the [Export] attribute. Usage shows how to call the C# method.

```csharp
// Objective-C: +[FacebookSdk logEventWithEventName:parameters:]
// C#:
[Static]
[Export("logEventWithEventName:parameters:")]
void LogEventWithEventName(string eventName, NSDictionary parameters);

// Usage: FacebookSdk.LogEventWithEventName("event", params);
```

--------------------------------

### Facebook SDK Integration

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/MANIFEST.md

Illustrates integrating the Facebook SDK for MAUI, including initialization and event logging.

```csharp
FacebookSdk.InitializeSDK();
```

```csharp
FacebookSdk.EnableAutoLogAppEvents();
```

```csharp
FacebookSdk.LogEvent("purchase", parameters);
```

```csharp
FacebookSdk.Flush();
```

--------------------------------

### Facebook SDK Initialization for iOS and Android

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/configuration.md

Initialize the Facebook SDK using platform-specific methods. For iOS, it retrieves credentials from Info.plist. For Android, it uses the current activity.

```csharp
#if IOS
    var appId = NSBundle.MainBundle.ObjectForInfoDictionary("FacebookAppID").ToString();
    var clientToken = NSBundle.MainBundle.ObjectForInfoDictionary("FacebookClientToken").ToString();
    FacebookSdk.SetupWithAppId(appId, clientToken);
#elif ANDROID
    FacebookSdk.InitializeSDK(Platform.CurrentActivity, isDebug: false);
#endif
```

--------------------------------

### Initialize Google Cast Framework

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/googlecast.md

Call this method to initialize the Google Cast framework. Ensure this is called after the GoogleCastManager instance is created.

```csharp
using GoogleCast;

public partial class MainPage : ContentPage
{
    GoogleCastManager? googleCastManager;

    protected override async void OnAppearing()
    {
        base.OnAppearing();

        if (googleCastManager is null)
        {
            googleCastManager = new GoogleCastManager();
            googleCastManager.Configure();
            
            Debug.WriteLine("Google Cast initialized");
        }
    }
}
```

--------------------------------

### MauiFIRApp.AutoConfigure

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/firebase-app.md

Automatically configures Firebase using the GoogleService-Info.plist configuration file. This is the simplest way to initialize Firebase if you have the configuration file set up correctly.

```APIDOC
## MauiFIRApp.AutoConfigure

### Description
Automatically configures Firebase using the GoogleService-Info.plist configuration file.

### Method
Static

### Signature
```csharp
void AutoConfigure()
```

### Returns
void

### Example
```csharp
using Firebase;

public partial class App : Application
{
    public App()
    {
        InitializeComponent();
        
        // Auto-configure Firebase from GoogleService-Info.plist
        MauiFIRApp.AutoConfigure();
        
        MainPage = new AppShell();
    }
}
```
```

### Safe Firebase Initialization with Fallback

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/firebase-app.md

Handles Firebase initialization by first attempting auto-configuration for iOS or Mac Catalyst, and then falling back to manual configuration if auto-configuration fails. This ensures Firebase is initialized even if configuration files are missing or malformed.

```csharp
public async Task SafeFirebaseInitialization()
{
    try
    {
        #if IOS || MACCATALYST
        // Attempt auto-configuration
        MauiFIRApp.AutoConfigure();
        Debug.WriteLine("Firebase configured from plist");
        #endif
    }
    catch (Exception ex)
    {
        Debug.WriteLine($"Auto-configuration failed: {ex.Message}");
        
        try
        {
            // Fallback to manual configuration
            string fallbackAppId = GetFallbackAppId();
            string fallbackSenderId = GetFallbackSenderId();
            
            #if IOS || MACCATALYST
            MauiFIRApp.Configure(fallbackAppId, fallbackSenderId);
            Debug.WriteLine("Firebase configured manually");
            #endif
        }
        catch (Exception fallbackEx)
        {
            Debug.WriteLine($"Fallback configuration failed: {fallbackEx.Message}");
            await DisplayConfigurationError();
        }
    }
}
```

### Firebase Configuration Timing and Initialization

Source: https://github.com/communitytoolkit/maui.nativelibraryinterop/blob/main/_autodocs/api-reference/firebase-app.md

Configure Firebase early in the app lifecycle, such as in the OnStart method, to ensure services like Analytics and Messaging are ready. Includes error handling for initialization failures.

```csharp
public partial class App : Application
{
    public App()
    {
        InitializeComponent();
    }
    
    protected override async void OnStart()
    {
        // Configure Firebase early in app lifecycle
        #if IOS || MACCATALYST
        try
        {
            MauiFIRApp.AutoConfigure();
            
            // Initialize other Firebase services
            await InitializeAnalytics();
            await InitializeMessaging();
        }
        catch (Exception ex)
        {
            Debug.WriteLine($"Firebase initialization failed: {ex.Message}");
        }
        #endif
    }
    
    private async Task InitializeAnalytics()
    {
        MauiFIRAnalytics.SetUserId(GetUserId());
        MauiFIRAnalytics.LogEvent("app_started", new NSDictionary());
    }
    
    private async Task InitializeMessaging()
    {
        var token = MauiFIRMessaging.FcmToken;
        if (!string.IsNullOrEmpty(token))
        {
            await SendTokenToBackend(token);
        }
    }
}
```
