loadCollection method

Implementation

@override
Future<void> loadCollection() async {
  isLoading = true;
  final snap = await ref.get();
  docs = [];
  for (final snapDoc in snap.docs) {
    final docData = snapDoc.data() as Map<String, dynamic>?;
    docs.add(newDoc(id: snapDoc.id)..parse(docData ?? {}));
  }
  isLoading = false;
}
