Android Studio配置：
1.配置 android\app\src\main\AndroidManifest.xml文件
在AndroidManifest.xml的application标签中配置Key(这一步不要搞错了。是application标签中配置Key)：
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="您的Key"/>
在AndroidManifest.xml中配置权限:
//地图包、搜索包需要的基础权限
<!--允许程序打开网络套接字-->
<uses-permission android:name="android.permission.INTERNET" />
<!--允许程序设置内置sd卡的写权限-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!--允许程序获取网络状态-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--允许程序访问WiFi网络信息-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--允许程序读写手机状态和身份-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--允许程序访问CellID或WiFi热点来获取粗略的位置-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
开始安装：
dependencies:
amap_location_fluttify: ^0.2.7+d2eb645
导入：
import 'package:amap_location_fluttify/amap_location_fluttify.dart';
使用：
await AmapCore.init('ios key');//IOS需要，安卓不需要
if (await requestPermission()) {
await AmapLocation.startLocation(
once: true,
locationChanged: (location) {
_location = location;
setState(() {});
},
);
}
