Asynchronous routing

[Ambassador-of-programming]

Fail to implement asynchronous routing in Flet. How can it be done?

I have synchronous routing that works and I want to rewrite it to asynchronous routing

main.py:

import flet as ft
from router import Router

def main(page: ft.Page):
    myRouter = Router()
    page.on_route_change = myRouter.route_change
    page.add(
        myRouter.body
    )
    page.go('/statistics')


ft.app(target=main)

route.py:

class Router:
    def __init__(self):
        self.routes = {
            "/statistics": statistic(),
        }
        self.body = ft.Container(content=self.routes['/statistics'])

    def route_change(self, route):
        routes = {
            "/statistics": statistic(),
        }
        body = ft.Container(content=self.routes['/statistics'])
        self.body.content = self.routes[route.route]
        self.body.update()

st.py:

import flet as ft

def statistic():
    content = ft.Column(
        [
            ft.Row(
            [
                ft.Text("Моя статистика", size=30), 
                ft.IconButton(icon=ft.icons.ANALYTICS, icon_size=30),
                ], 
            alignment=ft.MainAxisAlignment.CENTER
            ),

            ft.Row(
                [
                    ft.Text("Раздел моя статистика находится на стадии разработки. В новых обновлениях она появится")
                ]
            ),

        ]
    )
    return content

I made some modifications to your code. I actually just added _async and await where necessary.

class Router:
    def __init__(self):
        self.routes = {
            "/statistics": statistic(),
        }
        self.body = ft.Container(content=self.routes["/statistics"])

    async def route_change(self, route):
        routes = {
            "/statistics": statistic(),
        }
        body = ft.Container(content=self.routes["/statistics"])
        self.body.content = self.routes[route.route]
        await self.body.update_async()


def main(page: ft.Page):
    myRouter = Router()
    page.on_route_change = myRouter.route_change
    page.add_async(myRouter.body)
    page.go_async("/statistics")


ft.app_async(target=main)
