How is imageDatastore initialised?
Say an array can be initialised as A = zeros(1,3);
How a datastore is initialised?

ImageDatastore variables are usually initialized as mentioned in the documentation here https://www.mathworks.com/help/matlab/ref/matlab.io.datastore.imagedatastore.html
Could you please tell you use case and why you wish to initialize it as null?

Ans:- To create a new imagedatastore (just like a new folder) to which I can selectively add on specific images after some operations performed(in matlab).

That use case is not supported as it would require recreating the datastore on every image addition.
If you wish to do so, you can create the datastore with one image. Programatically add an image to the location od your datastore, and then recreate the datastore from that location.

Try the following syntax...
imgs=imageDatastore({});
I have used it in MatlabR2019a. Hope it will work for you.
