Null type becomes BOOL

[sergiors]

Is your feature request related to a problem? Please describe.

I did a stream to copy dynamodb to elasticsearch, I used the object DynamoDBStreamEvent, until that okey,
but when I try get the values, the null type becomes a boolean type.

Describe the solution you'd like

I read the source-code the AttributeValue.null_value and think the null value should back to python native value, like described in boto3 types

Describe alternatives you've considered

Additional context

As alternative to fix the stream copy, the only value that I need to check is the null value.

{k: v.get_value if not v.null_value else None for k, v in dct.items()}

Thanks for opening your first issue here! We'll come back to you as soon as we can.

Been a while since i did this, but if this is for deserialization, then "NULL": true would map to Python None.

I will double check @heitorlessa

Ok i made a PR to fix this (#929). It would be a breaking change (if you where expecting null_value to return a boolean), however this was the wrong behavior.

FYI, get_value is a convenient way to get the value out.
