Answer 4

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.

Answer 5

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.
