iOS: includeMetadataChanges does not recieve isFromCache false after first run

[ramsayamarin]

Steps to reproduce

Create a snapshot query like this example:

final query = templateQuery
          .startAt([geoHash])
          .endAt(['$geoHash~'])
          .limit(geoHashFetchCount)
          .snapshots(includeMetadataChanges: true)
          .listen(
            (snapshot) {
              if (snapshot.metadata.isFromCache) {
                return;
              }
             else...

Expected results

The docs say the following about includeMetadataChanges:

Whether the snapshot was created from cached data rather than guaranteed up-to-date server data. If you called DocumentReference. snapshots or Query. snapshots with includeMetadataChanges parameter set to true you will receive another snapshot with isFromCache equal to false once the client has received up-to-date data from the backend.

Actual results

On an Android device, this is true, and the snapshot is received twice, from the cache and then from server, but on iOS a cached followed by a server snapshot is only delivered the first time the query is executed, and if the same query is recreated later on the same data, a server snapshot is not received until the target data is updated. This was not the case in previous versions of the Firebase plugins or on Android, but it appeared in the latest version on iOS when I updated the plugins.

Code sample

Code sample

```dart final query = templateQuery .startAt([geoHash]) .endAt(['$geoHash~']) .limit(geoHashFetchCount) .snapshots(includeMetadataChanges: true) .listen( (snapshot) { if (snapshot.metadata.isFromCache) { return; } else... //This part is never reached if the query gets recreated on the same data, unless the data is updated ```

This appears to be an issue with cloud_firestore. This should be reported on the flutterfire repository.

Closing from here as this plugin is not maintained on this repo.

Thank you
