Я пытаюсь показать карту в своем приложении, созданную с помощью флаттера, я использую этот виджет: flutter_map .
Когда я тестирую свое приложение в эмуляторе, все работает нормально :
Но когда я генерирую apk (используя команду: flutter build apk) для проверки на моем устройстве android, карта не отображается :
Мой главный.дарт:
import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong/latlong.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(title: new Text('Leaflet Maps')),
body: new FlutterMap(
options: new MapOptions(
center: new LatLng(40.71, -74.00), minZoom: 10.0),
layers: [
new TileLayerOptions(
urlTemplate:"https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
subdomains: ['a', 'b', 'c']),
new MarkerLayerOptions(markers: [
new Marker(
width: 45.0,
height: 45.0,
point: new LatLng(40.73, -74.00),
builder: (context) => new Container(
child: IconButton(
icon: Icon(Icons.location_on),
color: Colors.red,
iconSize: 45.0,
onPressed: () {
print('Marker tapped');
},
),
))
])
]));
}
}
My pubspe c .yaml:

description: A new Flutter project.
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

# The following section is specific to Flutter.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
Pd1: я не использую Google Maps, я использую OpenStreetMap.
Pd2: я тестирую apk на нескольких устройствах Android, всегда Карта пуста.
Есть предложения ??
