Components Fan Screen Manager

Attention! This is an experimental widget. Perhaps the wrong positioning of the screens with a large number of them.

Example of using MDFanScreenManager:

from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivymd.app import MDApp
from kivymd.uix.button import MDIconButton
from kivymd.uix.fanscreenmanager import MDFanScreen
from kivymd.uix.list import ILeftBodyTouch


Builder.load_string(
