findCollection method

Query<Map<String, dynamic>> findCollection()

Finds a CollectionReference of type Map<String, dynamic> based on specified _collectionPath.

If _tryAddLocalId is true then your data will also contain a local id field based on the _idFieldName specified in the constructor.

If you rather want to retrieve data in the form of T consider using the findCollectionWithConverter method instead.

Implementation

Query<Map<String, dynamic>> findCollection() {
  _log.info('🔥 Finding ${_collectionPath()} CollectionReference without converter..');
  return (_isCollectionGroup
          ? _firebaseFirestore.collectionGroup(_collectionPath())
          : _firebaseFirestore.collection(_collectionPath()))
      .withConverter<Map<String, dynamic>>(
    fromFirestore: (snapshot, _) {
      final data = snapshot.data() ?? {};
      try {
        return data
            .tryAddLocalId(
              snapshot.id,
              idFieldName: _idFieldName,
              tryAddLocalId: _tryAddLocalId,
            )
            .tryAddLocalDocumentReference(
              snapshot.reference,
              referenceFieldName: _documentReferenceFieldName,
              tryAddLocalDocumentReference: _tryAddLocalDocumentReference,
            );
      } catch (error) {
