Question

i am trying to maximise the window based on a condition. while it is running the background, it is minimised and hidden.

Code sample

import flet as ft
import time as t
from datetime import datetime, timedelta
import threading

def main(page: ft.Page): 

    def reminder_dlg(e):
        def confirm_datetime(e): 
            if not date.value or not hour.value or not minute.value:
                page.snack_bar = ft.SnackBar(ft.Text("Please select all fields"))
                page.snack_bar.open = True
                page.update()
                return

            # Parse and format selected date and time
            parsed_date = datetime.strptime(date.value, "%a, %d %b %Y") 
            formatted_date = parsed_date.strftime("%Y-%m-%d")
            datetime_string = f"{formatted_date} {hour.value}:{minute.value}"
            selected_datetime = datetime.strptime(datetime_string, "%Y-%m-%d %H:%M")
            
            reminder_list.append(selected_datetime)
            dlg.open = False
            page.snack_bar = ft.SnackBar(ft.Text(f"Reminder set for: {selected_datetime}"))
            page.snack_bar.open = True
            print(reminder_list)
            page.update()

            page.update()
        t.sleep(1)  

    # Run the reminder function in the background
    threading.Thread(target=reminder, daemon=True).start()

    page.add(ft.ElevatedButton(text="set reminder",on_click=reminder_dlg))

ft.app(target=main)
