打开静态uri时flutter map_view崩溃

Question

我有一个map_view，并使用staticMapURI来显示完整视图的地图，但是当我点击地图时，应用崩溃了：

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(
    churchStaticMarkers,
    maptype: StaticMapViewType.roadmap,
    center: churchLocation
);

var churchMapContainer = new Container(

    },
  ),

);

Answer 1

即使Flutter是为跨平台开发的，但并非所有内容都是用Dart编写的。有些部分需要platform specific (native) code。因此，您需要在代码中添加一些内容（请参见pub.dartlang.org）

Android

您将对AndroidManifest.xml文件进行多次编辑。在Flutter项目中，您可以在android / app / src / main

下找到此文件位置

在您的AndroidManifest.xml中，在代码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"/>

在您的AndroidManifest.xml中，在application标记内添加以下行。确保用您生成的密钥替换your_api_key。

 <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.xml

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

在您的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Android设备或模拟器上运行您的应用程序。确认显示地图时您会看到地图详细信息。如果您仅看到米色屏幕，则可能是您的API密钥不正确。

iOS

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。 示例：

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

编辑：

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

initialCameraPosition: new CameraPosition(initialPosition)
