flet-extend

[ssseee66]

I extended the flet application plug-in with a flutter plug-in I wrote to listen for PDA broadcast events, and the TextField control returned in my flutter package < package _ name >.dart. Now I add the returned control to the flet application via a Python control, It works fine, but I don't know how to get the control and the control properties, like TectField.text (returning the control as TextField in the Flutter package) and do the next data processing. I hope you can help me, thank you!!
I am a Chinese, English is not very good, I hope you can understand my meaning and appeal.

class PdaListener extends StatefulWidget {
Control? parent;
late Control control;

PdaListener({

TextEditingValue(text: "扫描到数据:$data_code"));
Widget pda_control = TextField(controller: _controller);
return constrainedControl(

pda_listener.py

from flet_core.constrained_control import ConstrainedControl
from typing import Any, Optional
import flet as ft

class PdaListener(ConstrainedControl):
"""
PdaListener 控件。
"""

def __init__(self, pda_code = None):
    ConstrainedControl.__init__(self)
    self.pda_code = pda_code



def _get_control_name(self):
    return "pda_listener"

def before_update(self):
    super().before_update()
    self.pda_code = self._get_attr("pda_code")
   
@property
def pda_code(self):
    print("ksjsksj")
    print(self._get_attr("pda_code"))

    return self._get_attr("pda_code")
@pda_code.setter
def pda_code(self, value):
    self._set_attr("pda_code", value)

main.py

import flet as ft
from extend.python.controls.pda_listener import PdaListener
def main(page: ft.Page):
pda_listener = PdaListener()

page.add(ft.Text("Hello Flet!!!!!"))
page.add(pda_listener)

ft.app(main)

This is my main file, and I want to get the text value of the PdaListener() control in main.py

I added an instance of a Python control called PdaListener to the page, built as an apk that can listen to broadcasts on the PDA mobile terminal, and now I want to get this text value for the next step. How do I get the text value in the input field on the image, which is the control that I have been extended to get
