views/index_view.py

This is a basic python class whose view method takes page,params and basket and returns ft.view.

In page we get the page passed in Routing.

In params we get the object of Params class. In which all the values ​​extracted from the URL are in the form of variables.

It is not necessary that the name of the method should be view, you can also give a different name.

import flet as ft
from flet_route import Params,Basket

class IndexView:
    def __init__(self):
        ...

    def view(self,page:ft.page,params:Params,basket:Basket):
        print(params)
        print(basket)

        return ft.View(
            "/",
            controls=[
                ft.Text("This Is Index View"),
                ft.ElevatedButton("Go Next View", on_click=lambda _: page.go("/next_view/10")),
            ]
        )

views/next_view.py

import flet as ft
from flet_route import Params,Basket

class NextView:
    def __init__(self):
        ...

    def view(self,page:ft.page,params:Params,basket:Basket):
        print(params)
        print(basket)

        return ft.View(
            "/next_view/:my_id",
            controls=[
                ft.Text("This Is Next View"),
                ft.ElevatedButton("Go Index View", on_click=lambda _: page.go("/")),
            ]
        )
