[Ho]

Hi,
i need some help. i am using BottomNavigation for my app. Below is portion of my code. When i press 'Transaction', transaction screen displayed but the on_enter function was not called. i wan to achieve in such way that every time user press the navigation button that screen on_enter function was called. How can i achieve that??

Kv file:

MDBottomNavigation:
MDBottomNavigationItem:
name: 'Home'
text: 'home'
icon: 'apps'
HomeScreen: <= i put my homescreen here

MDBottomNavigationItem:
name: 'Transaction'
text: 'Transaction'
icon: 'autorenew'
Transaction: <= i put my transactionscreen here

py file:

class HomeScreen(Screen):
def on_enter(self):
print("Homescreen on enter was called")

class Transaction(Screen):
def on_enter(self):
print("TransactionScreen on enter was called")
