flutter firestore contains any query not fetching documents - flutter

Question

I have some documents stored under players in firebase and all of them have an id field with num value (e.g. 1, 3 or 25). now I only have 30 players but I'm trying to avoid getting all 30 player when I only need some to avoid unnecessary reads. I have a a list that has all the id of players I want and I'm trying to use arrayContainsAny to fix my problem like:
FirebaseFirestore.instance.collection('players').where("id", arrayContainsAny: widget.selectedPlayer);
where widget selected player is list as I said, I also tried using [1, 2] in place of widget.selectedPlayer but all of them returns no documents.
PS: I tried using is equal to and it works fine:
FirebaseFirestore.instance.collection('players').where("id", isEqualTo: 27)
here is my section of code
players = FirebaseFirestore.instance.collection('players').where("id", arrayContainsAny: widget.selectedPlayer);
return StreamBuilder<QuerySnapshot>(
stream: players.snapshots(),
builder: (BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
if (snapshot.hasError) {
return Text('Something went wrong');
}
if (snapshot.connectionState == ConnectionState.waiting) {
return Text("Loading");
}
var sortedPlayers = sortPlayersByPosition(snapshot.data.docs);
debugPrint("player docs: " + sortedPlayers.toString());
return ListView.builder(
padding: EdgeInsets.all(0.0),
itemCount: snapshot.data.docs.length + 1,
itemBuilder: (BuildContext context, int index) {
if (index == 0) {
// return the header
return playerHeaderRow(header);
}
index -= 1;
if (widget.selectedPlayer.contains(sortedPlayers[index]["id"])) {
return buildPlayers(sortedPlayers[index]);
} else {
// need to return a empty widget here but return null stop the loop when we come to a false case
// this will create a empty widget : https://stackoverflow.com/a/55796929
return SizedBox.shrink();
}
},
);
},
);

ok so if you want to use this function "An in query returns documents where the given field matches any of the comparison values."
you are suppose to use wherein and not arraycontainsany, I wish they had a doc somewhere for this
