高德地图定位flutter组件。
目前实现直接获取定位和监听定位功能。
注意:随着flutter版本的提升, 本项目也会随之更新,
感谢群友 @a396901990 ,目前已经修复了因为使用simple_permissions导致ios不能编译使用的问题
xcode10下如果出现 Multiple commands produce这个错误,参考这篇https://www.jianshu.com/p/8a8444acdca5,亲测可以解决。
如果有疑问或者对这个库感兴趣,可以加qq群:854192563一起探讨
A new flutter plugin project.
Getting Started #
集成高德地图定位android版本 #
1、先申请一个apikey
http://lbs.amap.com/api/android-sdk/guide/create-project/get-key
2、修改 你的项目目录/app/build.gradle
在android/defaultConfig节点修改manifestPlaceholders,新增高德地图key配置
android {
.... 你的代码
defaultConfig {
.....
manifestPlaceholders = [
AMAP_KEY : "aa9f0cf8574400f2af0078392c556e25", /// 高德地图key
]
}
...你的代码
dependencies {
/// 注意这里需要在主项目增加一条依赖,否则可能发生编译不通过的情况
implementation 'com.amap.api:location:latest.integration'
...你的代码
}

集成高德地图定位ios版本 #
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
import 'package:amap_location/amap_location.dart';
void main(){
AMapLocationClient.setApiKey("你的key");
runApp(new MyApp());
}
copied to clipboard
2、在info.plist中增加:
注意必须要描述清楚app使用定位的目的,苹果审核的时候要看,
如果写的不清楚,可能会被苹果拒绝上架,作者有过几次惨痛经历 :(
<key>NSLocationWhenInUseUsageDescription</key>
<string>要用定位</string>

怎么用 #
先导入dart包
修改pubspec.yaml,增加依赖:
dependencies:
amap_location:
copied to clipboard
在要用的地方导入:
import 'package:amap_location/amap_location.dart';
copied to clipboard
先启动一下
await AMapLocationClient.startup(new AMapLocationOption( desiredAccuracy:CLLocationAccuracy.kCLLocationAccuracyHundredMeters ));
copied to clipboard
直接获取定位:
await AMapLocationClient.getLocation(true)
copied to clipboard
监听定位
AMapLocationClient.onLocationUpate.listen((AMapLocation loc){
if(!mounted)return;
setState(() {
...
});
});
AMapLocationClient.startLocation();
copied to clipboard
停止监听定位
AMapLocationClient.stopLocation();
copied to clipboard
不要忘了在app生命周期结束的时候关闭
@override
void dispose() {
//注意这里关闭
AMapLocationClient.shutdown();
super.dispose();
}
copied to clipboard
注意点: #
在android6以上最好手动获取定位权限
在example中以simple_permissions这个库为例:
void _checkPersmission() async{
bool hasPermission = await SimplePermissions.checkPermission(Permission.WhenInUseLocation);
if(!hasPermission){
bool requestPermissionResult = await SimplePermissions.requestPermission(Permission.WhenInUseLocation);
if(!requestPermissionResult){
Alert.alert(context,title: "申请定位权限失败");
return;
}
}
AMapLocationClient.onLocationUpate.listen((AMapLocation loc) {
if (!mounted) return;
setState(() {
location = getLocationStr(loc);
});
});
AMapLocationClient.startLocation();
}
