feat: Create folders from array

**Description**

It is common to have Flutter projects with many different platforms, such as Andrid, iOS, etc. and it would be nice to be able to select what platforms we want from an array, then generate only the folders that are contained in the array.

I tried to find an example on how to achieve this, but I couldn't find any, nor to come up with some mustache template to make it work.

**Requirements**

- [ ] Create a folder only if the folder name is included in the variable array.
