[CLOUD_FIRESTORE]: Windows app crashes while tying to get a document about flutterfire HOT 3 OPEN

UPDATE:

In my application, I had disabled Firestore persistence. I tested re-enabling it, and the error did not occur anymore. It worked!

From this

FirebaseFirestore.instance.settings = const Settings(persistenceEnabled: false);

To this

FirebaseFirestore.instance.settings = const Settings(persistenceEnabled: true);

from flutterfire.

I have changed FirebaseFirestore.instance.settings = const Settings(persistenceEnabled: true); but the problem still exists. If I remove firebase folders from %LOCALAPPDATA% the app runs for a single time. but the problem still exists.

Hi @encoder90

Yes, you are correct. I celebrated too soon...

For some reason, using Firestore persistence, after the first access, the LDB and/or CURRENT files get corrupted. This only happens on some machines and I couldn't identify a pattern among them.

So, what I did to solve it was to clear the persistence as soon as Firebase is initialized, even before opening any screen in the app.

It looks like this:

void main() async {
WidgetsFlutterBinding.ensureInitialized();

await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

FirebaseFirestore.instance.settings = Settings(
// Curiously, it is necessary to enable persistence to avoid a crash where the database of
// this cache is not found. However, it is necessary to clear this same cache to avoid the crash due to it being corrupted.
// #12987
persistenceEnabled: Platform.isWindows,
);

// Curiously, it is necessary to enable persistence to avoid a crash where the database of
// this cache is not found. However, it is necessary to clear this same cache
// to avoid the crash due to it being corrupted.
if (Platform.isWindows) {
await FirestoreMF.instance.clearPersistence();
}

I do this only on Windows, as I haven't tested it on other platforms. In any case, it worked in the tests I did.
