R-JunmingChen opened a new issue, #38457: URL: https://github.com/apache/arrow/issues/38457
### Describe the enhancement requested Currently, `DictionaryArray.null_count()` counts the number of nulls among the dict indices, but ignores nulls among dict values. It will be useful that we can count the same of the null number as the DictionaryArray is decoded. That would also help #37100. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
