RecordPatchBody typedef
Fields to change: {"field": value} sets, {"field": null} clears an optional field; absent fields are unchanged. On a top-level integer or double field, {"$increment": delta} atomically adds a finite delta to the stored value (missing/null starts at zero); integer deltas and results must be safe integers, and field bounds apply to the result.
Implementation
typedef RecordPatchBody = Map<String, Object?>;
