打开静态 URI 时颤振map_view崩溃

Question

我有一个map_view并使用staticMapURI显示完整的视图地图，但是当我点击地图的那一刻，应用程序崩溃了：

我在其他帖子中读到您需要确保您的依赖项匹配等，但是当我尝试链接帖子中显示的内容时，我似乎可以让它工作。

我当前的依赖项如下所示：

任何人都可以深入了解如何解决此问题吗？

更新：

import 'package:map_view/map_view.dart';
import 'CompositionSubscription.dart';
import 'package:flutter/material.dart';
class CustomMap extends StatefulWidget {
String mapTitle;
List markers;
CameraPosition initialPosition;
CustomMap(this.mapTitle, this.markers, this.initialPosition);
@override
CustomMapState createState() => new CustomMapState(this.mapTitle, this.markers, this.initialPosition);
}
class CustomMapState extends State<CustomMap>  {
final String mapTitle;
final List<Marker> markers;
final CameraPosition initialPosition;
CustomMapState(this.mapTitle, this.markers, this.initialPosition);
MapView mapView = new MapView();
var compositeSubscription = new CompositeSubscription();
@override Widget build(BuildContext context) {
mapView.show(
new MapOptions(
mapViewType: MapViewType.normal,
showUserLocation: true,
initialCameraPosition: initialPosition,
title: mapTitle),
toolbarActions: [new ToolbarAction("Back", 1)]
);
var setMarkers = mapView.onMapReady.listen((_) {
mapView.setMarkers(markers);
mapView.zoomToFit(padding: 100);
});
compositeSubscription.add(setMarkers);
var toolbarAction = mapView.onToolbarAction.listen((id) {
if (id == 1) {
Navigator.pop(context);
mapView.dismiss();
compositeSubscription.cancel();
}
});
compositeSubscription.add(toolbarAction);
return new Scaffold();
}
}

在点击地图的上一个屏幕中。

var churchStaticMarkers = [ new Marker("Church", "St Dunstan's Church", 51.0206245,0.2605629, color: Colors.red)];
var churchLocation = new Location(51.0206245, 0.2605629);
var staticMapProvider = new StaticMapProvider("XXXXX");
var churchStaticMapUri = staticMapProvider.getStaticUriWithMarkers(

尽管 Flutter 是为跨平台而制作的，但并非所有内容都是用 Dart 编写的。某些部分需要特定于平台的(本机(代码。因此，需要将一些内容添加到代码中(请参阅 pub.dartlang.org(

人造人

您将对 AndroidManifest.xml 文件进行多次编辑。在你的 Flutter 项目中，你可以在 android/app/src/main 下找到这个文件位置。

在 AndroidManifest.xml 中，在标记上方添加以下使用权限。

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

在 AndroidManifest.xml 中，在应用程序标记中添加以下行。请务必将your_api_key替换为生成的一个。

<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your_api_key"/>
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>

将 MapActivity 添加到您的 AndroidManifest 中.xml

<activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/>

在你的android/build.gradle文件中。在 buildScript 依赖项下添加：

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-4'

在安卓设备或模拟器上运行您的应用程序。确认在显示地图时会看到地图详细信息。如果您只看到米色屏幕，则可能是您的 API 密钥不正确。

苹果

地图插件将在需要时请求您的用户位置。 iOS 要求您在 Info.plist 文件中解释此用法 在ios/Runner/Info.plist中设置NSLocationWhenInUseUsageDescription。 例：

<key>NSLocationWhenInUseUsageDescription</key>
<string>Using location to display on a map</string>

编辑：

此外，您还应该将 MapOptions initialCameraPosition Location 包装在 CameraPosition 中

initialCameraPosition: new CameraPosition(initialPosition)
