page.views.append, how to add the control set generated by the subroutine

[ChinaGodzilla]

        page.views.append(
            View(
                "/",
                [
                    AppBar(title=Text('疼讯新闻'), center_title=True, color='white', bgcolor=flet.colors.BLUE),
                    ElevatedButton("Visit Store", on_click=lambda _: page.go("/store")),


                ],
            )
        )

In the example, we only see the controls being inserted one by one.

                AppBar(title=Text('疼讯新闻'), center_title=True, color='white', bgcolor=flet.colors.BLUE),
                ElevatedButton("Visit Store", on_click=lambda _: page.go("/store")),

Now I'm using ListView to generate multiline text. How to insert this group? grateful

        lv = ListView(expand=True, spacing=10)


        for i in Url_list:
            List_split = str(i).split('|')
            lv.controls.append(
                Text(spans=[TextSpan(List_split[0], url=List_split[1], url_target='_self')], size=17))

I personally don't really understand your question. Please can you better explain and possibily share some runnable code repro?

@ndonkoHenri

thank you for your reply. I'm very sorry. When I asked the question before, I took some code snippets from my program group and couldn't complete the demo. Below is my rearranged code 1

import flet as ft

def main(page: ft.Page):
    page.title = "Routes Example"

    def route_change(route):
        page.views.clear()
        page.views.append(
            ft.View(
                "/",
                [
                    ft.AppBar(title=ft.Text("Flet app"), bgcolor=ft.colors.SURFACE_VARIANT),
                    ft.ElevatedButton("Visit Store", on_click=lambda _: page.go("/store")),
                    #At this location I want to insert a multiline text set control generated by another of my subroutines
                ],
            )
        )

        page.update()

    def view_pop(view):
        page.views.pop()
        top_view = page.views[-1]
        page.go(top_view.route)

    page.on_route_change = route_change
    page.on_view_pop = view_pop
    page.go(page.route)


ft.app(target=main)

Below is my subroutine to generate a multi-line text box that I want to display on the routine view.

from flet import *

lv = ListView(expand=True, spacing=10)

def Create():
    for i in range(99):
        lv.controls.append(
            Text(spans=[TextSpan(str(i), url='www.x.com', url_target='_self')], size=17))
    
    #return Here I don't know how to save the generated text box and insert it where I want to insert code 1 

    

My purpose is to insert the second subroutine into the first code, because page.views.append in the first code can only add specified controls.

thanks for your time

I would try something like this:

def create():
    lv = ListView(expand=True, spacing=10)

    for i in range(99):
        lv.controls.append(
            Text(spans=[TextSpan(str(i), url='www.x.com', url_target='_self')], size=17))

    return lv

Then, where you want the control, just add the call to the create().

You must have a listview, which you have if you do the return of lv. This listview will be added to the page.
