initializeApp method Null safety

Future<FirebaseApp> initializeApp(
  1. {String? name,
  2. FirebaseOptions? options}
)

Initializes a new FirebaseApp instance by name and options and returns the created app. This method should be called before any usage of FlutterFire plugins.

The default app instance can be initialized here simply by passing no "name" as an argument in both Dart & manual initialization flows.

Implementation

static Future<FirebaseApp> initializeApp({
  String? name,
  FirebaseOptions? options,
}) async {
  FirebaseAppPlatform app = await _delegate.initializeApp(
    name: name,
    options: options,
  );

  return FirebaseApp._(app);
}
