问题 I am looking to store fetch data from firestore into a List which would contain data from all of its documents. I defined list as : List retrievedData = List(); next, on press of button, I wanted to print data in all documents of a specific collection.

问题 I'm trying to query a few documents from a collection, this query should listen to changes made in the queried documents, so I'd need a stream. I'm doing following (in Dart/Flutter) Stream<List<MatchRequest>> _getNewMatches() { return Collection<MatchRequest>(path: 'requests') .ref .where('status', isNull: true) .where('users', arrayContains: ['$currentUid']) .orderBy('last_activity') .snapshots() .map((list) => list.documents.map( (doc) => Global.models[MatchRequest](doc.data) as

I wrote a quick hack to allow for importing these JSON in the Firebase Simulator Firestore instance. I proposed a pull request and made this npm module in the meantime. You can use it this way: const
