whereContainsAll method
Add a constraint to the query that requires a particular key's value match another ParseQuery.
This only works on keys whose values are ParseObject or lists of ParseObjects. Add a constraint to the query that requires a particular key's value to contain every one of the provided list of values.
Implementation
void whereContainsAll(String key, List<dynamic> values) {
_addCondition(key, "whereContainsAll", values);
}
