need help with navigation \ passing params with function

[NiroDev26]

hello
i'm building flet app, i have router file that handles the routing,
a main page with table of rows with objects, and a button in each row
that when clicked, should open a new page and pass a param with that call.
at the moment i have a func from mainpage that calls secondpage(page) and i cannot manage
to pass a param with that secondpage(page) function to use an object on secondpage..

this is the button:
details = ft.DataCell(
ft.IconButton(
ft.icons.CAR_REPAIR_SHARP,
#on_click=lambda _: self.page.route("/details", vehicle=vehicle),
#on_click=on_details_click,
on_click=lambda _: self.page.go("/details"),# route_params={"vehicle_id": vehicle.car_id}),
style=ft.ButtonStyle(color=ft.colors.BLUE)
)
)

this is the router:
class MyRouter:

def __init__(self, page):
    self.page = page
    self.ft = ft
    self.routes = {
        "/": Home(page),
        "/mainscreen": MainTable(page),
        "/details": DetailsView(page),
        "/addnewcar": AddNewCar(page),
    }
    self.body = ft.Container(content=self.routes['/'])

def route_change(self, route):
    self.body.content = self.routes[route.route]
    self.body.update()

thanks for your help
