            [

        self.open = False
        #This gonna keep False after refreshing, so use "set_open_modal with on_connect to update on refreshing"
        self.page.update()

    def build(self):
        # Have to set in build, cuz here you can use self.page (unless you init self.page = page) at constructor, didn't try)
        self.page.on_connect = self.set_open_modal

    def set_open_modal(self, e):
        # when you close the modal using "self.open = False" it keeps "False after refreshing",
        # so here, set "self.open = True", this func gonna be call in "on_connect", so this replace the previouse                # "self.open = False" to True.
        self.open = True
        self.page.update()


def main(page: ft.Page):

    page.views.append(view)
    page.update()
