update method

Future<T?> update(String key, Map<String, dynamic> updateFields, { T? currentData, })

Partially updates an existing entry in the store.

Updates the entry under key. This is a partial update that will only change the fields specified in updateFields, all other fields of the entry stay unchanged. To delete a field, add it with null to updateFields.

By default, always returns null. However, if you specify currentData, if the request succeeds, the currentData will be patched with updateFields and the patched entry returned, mirroring the current state on the server, given that currentData is the same as the previous server state.

Implementation

Future<T?> update(
  String key,
  Map<String, dynamic> updateFields, {
  T? currentData,
}) async {
  final response = await restApi.patch(
    updateFields,
    path: _buildPath(key),
    printMode: currentData == null ? PrintMode.silent : null,
  );
  return currentData != null
      ? patchData(currentData, response.data as Map<String, dynamic>)
      : null;
}
