[firebase-storage] useStorageEmulator() should set default-bucket

[jarrodonlo]

Calling useStorageEmulator(host, port) should also set the bucket = "default-bucket".

Although Firebase Emulator uses "default-bucket" as bucket name...
(On package firebase_storage) calling useStorageEmulator() does not use this bucket by default, which seems like it would be expected behavior, as all users must do this manually. Instead, continuing to use bucket setup from flutterfire cli generated FirebaseOptions.

Instead of doing one line...

FirebaseStorage.instance.useStorageEmulator('localhost', 9199);

the user must currently do two lines to use emulator...

FirebaseStorage.instance.bucket = 'default-bucket'; // must be done prior! (order matters)
FirebaseStorage.instance.useStorageEmulator('localhost', 9199);

this was a tripping point for myself, I feel like it will be for other new users.

Thank you for the advice. I was struggling for hours to connect StorageEmulators. It works after adding the suggested line.
FirebaseStorage.instance.bucket = 'default-bucket';
