Possibility to replace nullValue default value to 'NULL_VALUE' instead of 0

[jrtderonde]

Hi,

I've been using this package for a project where I retrieve data from Google DialogFlow CX. I have been using it to compare certain user input to the input that's stored within DialogFlow CX. A few weeks ago, the implementation falsely compares two similar objects due to a (possible) change within Google's IStruct interface (?).

I found the following. DialogFlow CX is returning a null value as NULL_VALUE. The package, however, returns a null value as a 0.

DialogFlow CX: "nullValue": "NULL_VALUE"
This package: "nullValue": 0

Just wanted to create this issue to inform and/or check if there is a possibility to implement a different value for the null value or what would be your approach in this.

Kind regards,
J.
