I was running unit test in flutter and I am getting error as
type ‘List’ is not a subtype of type ‘List<DocumentReference<Map<String, dynamic>>>’

The related code snippet is as follows where I am trying to read data from the firebase.

 factory TimerSessionModel.fromSnapshot(
      DocumentSnapshot<Map<String, dynamic>> snapshot) {
    final data = snapshot.data()!;
    return TimerSessionModel(
      selfRef: snapshot.reference,
      activeExecutionRef: data['activeExecutionRef'],
      autoStartNextTimer: data['autoStartNextTimer'] as bool,
      ownerRef: data['ownerRef'],
      timerRefs: data['timerRefs'],
      title: data['title'] as String,
    );
  }

Here timerRefs is a list of document references, where the problem is pointing to.

I tried to run the unit test and gives me and error as above mentioned
