Please help me find the reason for this code behaviorThere are 3 identical boxes (flet Container()) with switch (flet Switch()).Only switch in first box "unit_view1" is available for switching. Other two are not.Why ???I can't find any reason that interferes with the behavior of the switches
import flet as ftdef _name_row(unit_name): return ft.Container(alignment=ft.alignment.center, content=ft.Text(value=unit_name, size=36))def set_on_off(value): print("unit is", "on" if value else "off")class Unit(ft.UserControl): def __init__(self, unit_name: str): super().__init__() self.unit_name = unit_name def build(self): _cnt = ft.Container( padding=10, width=250, border=ft.border.all(3), border_radius=30, content=ft.Column( controls=[ ft.Switch( label="Вкл", active_color="green", on_change=set_on_off ), ft.Divider(), _name_row(self.unit_name), ft.Divider(), ] ) ) return _cntclass UnitsView(ft.UserControl): def __init__(self): super().__init__() self.unit_view1 = Unit(unit_name="Unit 1") self.unit_view2 = Unit(unit_name="Unit 2") self.unit_view3 = Unit(unit_name="Unit 3") def build(self): _cnt = ft.Container( alignment=ft.alignment.center, padding=50, width=400, content=ft.Row( spacing=10, controls=[ self.unit_view1, ft.VerticalDivider(), self.unit_view2, ft.VerticalDivider(), self.unit_view3, ], ), ) return _cntdef main(page: ft.Page): page.window_width = 960 page.window_height = 300 page.add(UnitsView())if __name__ == "__main__": ft.app(target=main)View of appI tested a similar one without classes, I only use simple Flet controls it and it works there.
