Description

There is currently no API in the PrimitiveArrayBuilder class to support writing nulls.  See this TODO - https://github.com/apache/arrow/blob/1515fe10c039fb6685df2e282e2e888b773caa86/csharp/src/Apache.Arrow/Arrays/PrimitiveArrayBuilder.cs#L101.

 

Also see https://github.com/apache/arrow/issues/5381.

 

We should add some APIs to support writing nulls.
