tu veux prouver quoi à qui ? 😔

Magnificent

This is simple implementation of Brainf*ck esoteric language so there is something a beginner could learn from it but absolutely do not consider that a production quality code 👌.

Absolutely insane solution, but as a Dart beginner I learned so many techniques from this simple "Hello World" program.

In the Kata description: """ Your points are not included in the array of your class's points. For calculating the average point you may add your point to the given array! """

Your solution does not seem to include "your points".
Also '.reduce' fails if the list is empty. '.fold()' handles that case.
