/**
 * A custom ErrorHandler that captures uncaught errors and sends them to Firebase Crashlytics.
 *
 * This should be provided in your application's root module.
 *
 * @example
 * Basic usage:
 * ```typescript
 * import { ApplicationConfig, ErrorHandler } from '@angular/core';
 * import { FirebaseErrorHandler } from 'firebase/crashlytics-angular';
 *
 * export const appConfig: ApplicationConfig = {
 *   providers: [
 *     {
 *       provide: ErrorHandler,
 *       useFactory: () => new FirebaseErrorHandler(firebaseApp)
 *     }
 *   ],
 *   // ...
 * };
 * ```
 *
 * @example
 * Providing telemetry options:
 * ```typescript
 * import { ApplicationConfig, ErrorHandler } from '@angular/core';
 * import { FirebaseErrorHandler } from 'firebase/crashlytics-angular';
 *
 * export const appConfig: ApplicationConfig = {
 *   providers: [
 *     {
 *       provide: ErrorHandler,
 *       useFactory: () => new FirebaseErrorHandler(firebaseApp, { appVersion: '1.2.3' })
 *     }
 *   ],
 *   // ...
 * };
 * ```
 *
 * @param firebaseApp - The {@link @firebase/app#FirebaseApp} instance to use.
 * @param crashlyticsOptions - Optional. {@link CrashlyticsOptions} that configure the Crashlytics instance.
 * To provide these options, you must use a `useFactory` provider as shown in the example above.
 *
