pushDelta method

@override Future<void> pushDelta({ required String collection, required String recordId, required Map<String, dynamic> delta, required int baseVersion, required DateTime timestamp, })

Push delta (partial update) to backend.

Only sends changed fields instead of the entire document, reducing bandwidth by up to 98%.

Parameters:

• collection: Collection name
• recordId: Document ID
• delta: Only the fields that changed
• baseVersion: Version before this update
• timestamp: When the update occurred

If the backend doesn't support delta sync, this should fall back to a regular push() with the full document.

Implementation

@override
Future<void> pushDelta({
  required String collection,
  required String recordId,
  required Map<String, dynamic> delta,
  required int baseVersion,
  required DateTime timestamp,
}) async {
  try {
    // ignore: deprecated_member_use
    await databases.updateDocument(
      databaseId: databaseId,
      collectionId: collection,
      documentId: recordId,
      data: {'data': delta, 'updated_at': timestamp.toIso8601String()},
    );
  } catch (e) {
    // ignore: deprecated_member_use
    await databases.createDocument(
      databaseId: databaseId,
      collectionId: collection,
      documentId: recordId,
      data: {
        'data': delta,
        'updated_at': timestamp.toIso8601String(),
        'version': 1
      },
    );
  }
}
