fl amap

高德地图定位flutter组件。
目前实现获取定位和监听定位功能。
1、申请一个key
http://lbs.amap.com/api/ios-sdk/guide/create-project/get-key
直接在dart文件中设置key
ios #

在info.plist中增加:

<key>NSLocationWhenInUseUsageDescription</key>
<string>要用定位</string>
copied to clipboard
如果ios定位没有返回逆地理信息,添加一下内容
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsForMedia</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>
/// 解决ios HTTP 警告,需要添加的
<key>NSExceptionDomains</key>
<dict>
<key>restios.amap.com/key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
</dict>
</dict>
</dict>

iOS 9及以上版本使用后台定位功能, 需要保证"Background Modes"中的"Location updates"处于选中状态

3.使用地理围栏
iOS14及以上版本使用地理围栏功能,需要在plist中配置NSLocationTemporaryUsageDescriptionDictionary字典描述,
且添加自定义Key描述地理围栏的使用场景,此描述会在申请临时精确定位权限的弹窗中展示。
该回调触发条件:拥有定位权限,但是没有获得精确定位权限的情况下,会触发该回调。此方法实现调用申请临时精确定位权限API即可;
** 需要注意,在iOS9及之后版本的系统中,如果您希望程序在后台持续检测围栏触发行为,需要保证manager的
allowsBackgroundLocationUpdates 为 YES,
设置为YES的时候必须保证 Background Modes 中的 Location updates 处于选中状态,否则会抛出异常。
android #

android/src/main/AndroidManifest.xml 添加以下内容 具体参考 example


<manifest>
<application>
/// 需要配置的
<meta-data android:name="com.amap.api.v2.apikey" android:value="您的Key" />
</application>
</manifest>

高德定位功能 #

设置key


Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();

final bool key = await setAMapKey(
iosKey: 'ios key',
androidKey: 'android key');

if (key != null && key) print('高德地图ApiKey设置成功');

runApp(MaterialApp(title: 'FlAMap', home: Home()));
}

初始化定位参数

Future<void> initialize() async {
/// 获取权限
if (getPermissions) return;

/// 初始化AMap
final bool data = await FlAMapLocation().initialize();
if (data) {
show('初始化成功');
}
}

copied to clipboard

单次获取定位

Future<void> getLocation() async {
/// 务必先初始化 并获取权限
if (getPermissions) return;
AMapLocation location = await FlAMapLocation().getLocation();
if (isAndroid) {
AMapLocation is AMapLocationForAndroid;
}
if (isIOS) {
AMapLocation is AMapLocationForIOS;
}
}

开启定位变化监听

Future<void> startLocationChange() async {
/// 务必先初始化 并获取权限
FlAMapLocation().addListener(

/// 连续定位回调 android & ios 均支持
onLocationChanged: (AMapLocation? location) {
locationState.value = location;
},

/// ios连续定位 错误监听 仅在ios中生效
onLocationFailed: (AMapLocationError? error) {
text.value = 'ios 连续定位错误:${error?.toMap()}';
},

/// 监听设备朝向变化 仅在ios中生效
onHeadingChanged: (AMapLocationHeading? heading) {
headingState.value = heading;
},

/// 监听权限状态变化 仅在ios中生效
onAuthorizationChanged: (int? status) {
text.value = 'ios 权限状态变化:$status';
});
}

copied to clipboard

关闭定位变化监听

void stopLocation() {
FlAMapLocation().stopLocation();
}
copied to clipboard

关闭定位服务

void dispose() {
FlAMapLocation().dispose();
}
copied to clipboard

开启前台任务 仅支持android 8.0 +
如需开启前台任务需要添加以下配置 至 android/src/main/AndroidManifest.xml 具体参考 example


<manifest>
/// 需要添加的权限
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<application>
/// 需要配置的服务
<service android:exported="false" android:foregroundServiceType="location" android:name="com.amap.api.location.APSService" />
</application>
</manifest>

void enableBackgroundLocation() {
FlAMapLocation().enableBackgroundLocation(
AMapNotificationForAndroid(
notificationId: 999,
title: '我在定位',
content: '我正在定位',
channelId: 'channelId',
channelName: 'name',
lightColor: Colors.red));
}

void disableBackgroundLocation() {
FlAMapLocation().disableBackgroundLocation();
}
