Login Screen kivy/kivymd

Question

I am creating an app using python (kivy and kivymd) and I have a login screen but every time I open my application I will get this screen,how can I make to appear once and disappear permanently?

Answer 1

Use a config file to store the information to decide whether to open the login screen.

Answer 2

The following code will help:

It tries to read a 'temp.txt' file

On first run , there is no such file and an exception will be thrown calling the except block

Code:

global k
try:
    with open('temp.txt','r') as file:
        p = file.read()
        global k
        k = False
except:
    global k
    with open('temp.txt','w') as file:
        file.write('1')
    k = True
class Management(ScreenManager):
    def __init__(self,*kwargs):
        global k
        if k:
            self.current = 'LoginScreen'
        else:
            self.current = 'HomeScreen'
