Code sample

import random
from flet import *
import flet.map as map
from geopy.geocoders import Nominatim

def main(page: Page):
    page.window_width = 500
    geolocator = Nominatim(user_agent="geoapiExercises")

    custom_marker = map.MarkerLayer(markers=[])


    from_location = TextField(label="You from location city")
    dest_location = TextField(label="You destination location city")

    def get_coordinates(location):
        location = geolocator.geocode(location)
        if location:
            return (location.latitude, location.longitude)
        else:
            return None

    def show_route(e):
        custom_marker.markers.clear()
        from_coords = get_coordinates(from_location.value)
        dest_coords = get_coordinates(dest_location.value)
        if from_coords and dest_coords:
            print(f"From Coordinates: {from_coords}")
            print(f"Destination Coordinates: {dest_coords}")

            custom_marker.markers.append(
                map.Marker(
                    content=Icon(name="location_on", color="red", size=30),

                )
            )
            # Center the map between the two locations
            center_lat = (from_coords[0] + dest_coords[0]) / 2

            map_instance.initial_center = map.MapLatitudeLongitude(center_lat, center_lon)
            map_instance.update()
            page.update()
        
    map_instance = map.Map(
        expand=True,

            on_init=lambda e: print(f"Initialized Map"),
        ),
        layers=[

The answer to this question interests me.
I have the same question for the "initial_zoom" parameter. I want to ZoomIn and ZoomOut from a Toolbar.
How do we programatically modify these parameters?
