How to display a random Flutter map?

Question

I am trying to display a random Flutter map using the flutter_maps package. When I was creating this, I couldn't find the 'layers' option under the map options. If I type layers I got an error "Parameter named 'layers' is not defined."

I have added all the required dependencies. How to solve this?

Code:

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong2/latlong.dart' as LatLng;

Container(                         //container 1
          height: 800,
          width: double.infinity,
          child: FlutterMap(
            options: MapOptions(
              center: LatLng.LatLng(23.77176, 90.399452),
              zoom: 8,
            ),
            ),
        ),

The layers option is not available in the MapOptions class of the flutter_map package. Instead, you can add one or more layers to the map using the children property of the FlutterMap widget:

return FlutterMap(
    options: MapOptions(
        center: LatLng(51.509364, -0.128928),
        zoom: 9.2,
    ),
    nonRotatedChildren: [
        AttributionWidget.defaultWidget(
            source: 'OpenStreetMap contributors',
            onSourceTapped: null,
        ),
    ],
    children: [
        TileLayer(
            urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png',
            userAgentPackageName: 'com.example.app',
        ),
    ],
);
