How do you get the depth of a List in flutter/ dart language, given a list like this one
List testRy = [1,2,[3,4,[5,6],7,[8,[9,91]],10],11,12];
Can you help me create something like an extension for doing that, that is callable from anywhere?

- This is not depth. This is the maximum length of a nested list as one of the elements of the original list. But this is not the depth of the list.mezoni– mezoni2023-09-27 10:35:17 +00:00Commented Sep 27, 2023 at 10:35

I found a solution!
Created a list extension as below:
extension Lists<E> on List<E> { int get depth { int depth = 0; getElementDepth(List list) { depth++; for (var item in list) { if (item is List) { getElementDepth(item); } } return depth; } return getElementDepth(this); } }and now I can call use it like this:
let test = [1,2,[3,4,[5,6],7,[8,[9,91]],10],11,12]; print(test.depth);
