引入高德地图组件

#地图插件
 amap_flutter_map: ^3.0.0
 # 定位插件
  amap_flutter_location: ^3.0.0 
并执行命令
flutter pub get

由于高德地图Flutter插件内不包含基础SDK包,所以需要单独引入地图基础SDK,在android文件加下的build.gradle文件中添加如下代码:

添加目录  我在项目 > android > app > build.gradle中配置如下:
/高德地图Flutter插件内不包含基础SDK包,使用时请参考官网关于集成Android地图SDK和iOS地图SDK说明配置地图SDK
    implementation('com.amap.api:3dmap:9.4.0')

配置权限

我在项目 > android > app > src > main > AndroidManifest.xml中配置如下:

配置权限(AndroidManifest.xml)
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.tianxi_user">
   <application
        android:label="tianxi_user"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <!-- 配置定位Service -->
        <service android:name="com.amap.api.location.APSService"/>
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"

实现地图 添加一个地图组件

import 'package:amap_flutter_map/amap_flutter_map.dart';
import 'package:flutter/cupertino.dart';

import '../../map/const_config.dart';
/*政府端
* 实时监控*/
class GovernmentMonitorPage extends StatefulWidget{
  @override
  State<StatefulWidget> createState() =>GovernmentMonitorState();
}

class GovernmentMonitorState extends State<GovernmentMonitorPage>{
  AMapController? _mapController;

  @override
  Widget build(BuildContext context) {
    ///使用默认属性创建一个地图
    final AMapWidget map = AMapWidget(
      privacyStatement: ConstConfig.amapPrivacyStatement,
      apiKey: ConstConfig.amapApiKeys,
      onMapCreated: onMapCreated,
    );

    return Container(
      height: MediaQuery.of(context).size.height,
      width: MediaQuery.of(context).size.width,
      // child: Text('11'),
      child: map,
    );
  }


  void onMapCreated(AMapController controller) {
    setState(() {
      _mapController = controller;
      getApprovalNumber();
    });
  }

  // 获取审图号
  void getApprovalNumber() async {
    //普通地图审图号
    String? mapContentApprovalNumber =
    await _mapController?.getMapContentApprovalNumber();
    //卫星地图审图号
    String? satelliteImageApprovalNumber =
    await _mapController?.getSatelliteImageApprovalNumber();
  }
}

ConstConfig.dart:

import 'package:amap_flutter_base/amap_flutter_base.dart';
import 'package:amap_flutter_map/amap_flutter_map.dart';

class ConstConfig {
  ///配置您申请的apikey,在此处配置之后,可以在初始化[AMapWidget]时,通过`apiKey`属性设置
  ///
  ///注意:使用[AMapWidget]的`apiKey`属性设置的key的优先级高于通过Native配置key的优先级,
  ///使用[AMapWidget]的`apiKey`属性配置后Native配置的key将失效,请根据实际情况选择使用
  static const AMapApiKey amapApiKeys = AMapApiKey(
      androidKey: '您申请的Andriod平台的key',
      iosKey: '您申请的iOS平台的key');

  ///高德隐私合规声明,这里只是示例,实际使用中请按照实际参数设置[AMapPrivacyStatement]的'hasContains''hasShow''hasAgree'这三个参数
  ///
  /// 注意:[AMapPrivacyStatement]的'hasContains''hasShow''hasAgree'这三个参数中有一个为false,高德SDK均不会工作,会造成地图白屏等现象
  ///
  /// 高德开发者合规指南请参考:https://lbs.amap.com/agreement/compliance
  ///
  /// 高德SDK合规使用方案请参考:https://lbs.amap.com/news/sdkhgsy
  static const AMapPrivacyStatement amapPrivacyStatement =
  AMapPrivacyStatement(hasContains: true, hasShow: true, hasAgree: true);
}
