how can i use ref in my costom control

Just as you would in a normal control I think. Or have you tried and it didn't work? In that case the error message would be helpful.

import flet as ft


class FullWidthTextInput(ft.UserControl):
    def __init__(
        self,
        ref: ft.Ref | None = None,
        lable: str = "",
        password: bool = False,
        on_change=None,
    ):
        super().__init__(ref=ref)
        self.text_field = ft.TextField(
            expand=True,
            height=70,
            border_radius=10,
            border_width=2,
            max_length=10,
            password=password,
            label=lable,
            border_color="#6954f2",
            bgcolor="#c9cdff",
            label_style=ft.TextStyle(color="#6954f2"),
            text_style=ft.TextStyle(
                color="#6954f2",
                size=16,
            ),
            content_padding=ft.Padding(left=10, right=5, top=0, bottom=10),
            on_change=on_change,
        )

    def build(self):
        return ft.Stack(
            [
                ft.Container(
                    expand=True,
                    height=70,
                    border_radius=10,
                    # bgcolor="#c9cdff",
                    margin=ft.Margin(left=10, right=10, top=0, bottom=0),
                    # on_click=self.on_click,
                    col=6,
                    content=self.text_field,
                )
            ],
            expand=True,
            height=70,
        )


def main(page: ft.Page):
    test_ref = ft.Ref[FullWidthTextInput]()

    def callme(e):
        print("changed")
        test_ref.current.text_field.label = "After"
        test_ref.current.update()

    input = FullWidthTextInput(ref=test_ref, lable="befor", on_change=callme)

    page.add(input)


ft.app(target=main, view=ft.WEB_BROWSER)

I came around to testing this and it works. Seems we both mistakingly believed the build() method would be called on every update.

while True:
    print("Thanks for the quick response. You deserve a big heart ❤️")

You're welcome, I'll take a ✅ too 😉

what do you mean?

I think this was meant as a reply to a question of mine in the answer thread.
