Description

I am using Realtime DB to write and read data from my Flutter app. Whenever I try to write some data to RTDB, the request is successful but it takes several minutes to finish it. The data has very short length and I am using some mock test values for now. After these minutes I get the breakpoint call on my .then() closure and I see the data on my Realtime DB.
I am experiencing the same delay for read operations. I am experiencing this in the simulator. When trying it on a real old device (Samsung S8), the closure completion is never reached, but I neither get an error.

The same RTDB is being used without any delay from iOS app built in Xcode+Swift.

Reproducing the issue

class RealtimeDatabaseClient {

  final publicGamesRef = FirebaseDatabase.instanceFor(
      app: Firebase.app('name'),
      databaseURL: "database-url"
  ).ref("test");

Future<void> createGame(
    int timestamp,
  ) async {
  await publicGamesRef.child(gameID).set({
    "timestamp": timestamp,
  }).then((_) {
    print("Data saved");
  }).catchError((error) {
    print("Realtime DB error");
  });
}
