Simply you can create observable model data list like

  List<SampleItem> sampleList = <SampleItem>[].obs;

You can create a list simply like:

final listHere = <ListTypeHere>[].obs;

A little bit differently from @Wesley's answer is the final which you can use for sake of efficiency since you will be using the .value.

You can specify the type of the list easily like this

var products = <Product>[].obs;

Try this

RxList<Product> product = (List<Product>.of([])).obs;

Actually i found the answer for this questions. This is the new way of declaring a list in flutter after the null safety update :

var products = [];

And to make it observable with Getx package we do it like this:

var products = [].obs;

But i dont know how to specify the type of the list in the declaration.
