Question

This todo example cannot be used.

Code sample

class TodoApp(ft.UserControl):
    def build(self):
        self.new_task = ft.TextField(hint_text='输入你的待办', expand=True)
        self.tasks = ft.Column()
        return ft.Column(
            width=600,
            controls=[
                ft.Row(
                    controls=[
                        self.new_task,
                        ft.FloatingActionButton(icon=ft.Icons.ADD, on_click=self.add_clicked),
                    ]
                ),
                self.tasks,
            ],
        )

    def add_clicked(self, e):
        self.tasks.controls.append(ft.Checkbox(label=self.new_task.value))
        self.new_task.value = ''
        self.update()

Error message

Try the (updated) code from docs: https://flet.dev/docs/tutorials/python-todo

(fyi: UserControl is no longer a Flet control - see the custom controls guide here)
