amap_flutter_demo: A Dart repository from CrassusX

迁移高德地图demo支持最新空安全 amap_flutter_map 基于高德开放平台地图SDK的flutter插件

Usage 使用Flutter插件，请参考在Flutter里使用Packages, 添加amap_flutter_map的引用

准备工作登录高德开放平台官网申请ApiKey。Android平台申请配置key请参考Android获取key, iOS平台申请配置请参考iOS获取key。引入高德地图SDK，Android平台请参考Android Sudio配置工程, iOS平台请参考ios安装地图SDK iOS端插件使用特殊配置:Flutter 1.22.0 之前(之后的版本可以不添加该配置)，iOS端的UiKitView还只是preview状态, 默认是不支持的, 需要手动打开开关, 需要在iOS工程的info.plist添加如下配置: io.flutter.embedded_views_preview YES 使用示例 import 'package:amap_flutter_map_example/base_page.dart'; import 'package:flutter/material.dart';

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

class ShowMapPage extends BasePage { ShowMapPage(String title, String subTitle) : super(title, subTitle); @override Widget build(BuildContext context) { return _ShowMapPageBody(); } }

class _ShowMapPageBody extends StatefulWidget { @override State createState() => _ShowMapPageState(); }

class _ShowMapPageState extends State<_ShowMapPageBody> { static final CameraPosition _kInitialPosition = const CameraPosition( target: LatLng(39.909187, 116.397451), zoom: 10.0, ); List _approvalNumberWidget = List(); @override Widget build(BuildContext context) { final AMapWidget map = AMapWidget( initialCameraPosition: _kInitialPosition, onMapCreated: onMapCreated, );

return ConstrainedBox(
  constraints: BoxConstraints.expand(),
  child: Stack(
    alignment: Alignment.center,
    children: [
      Container(
        height: MediaQuery.of(context).size.height,
        width: MediaQuery.of(context).size.width,
        child: map,
      ),
      Positioned(
          right: 10,
          bottom: 15,
          child: Container(
            alignment: Alignment.centerLeft,
            child: Column(
                mainAxisAlignment: MainAxisAlignment.start,
                children: _approvalNumberWidget),
          ))
    ],
  ),
);

}

AMapController _mapController; 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(); setState(() { if (null != mapContentApprovalNumber) { _approvalNumberWidget.add(Text(mapContentApprovalNumber)); } if (null != satelliteImageApprovalNumber) { _approvalNumberWidget.add(Text(satelliteImageApprovalNumber)); } }); print('地图审图号（普通地图）: $mapContentApprovalNumber'); print('地图审图号（卫星地图): $satelliteImageApprovalNumber'); } }

已知问题： Flutter插件在iOS端，MapView销毁时，一定概率触发Main Thread Checker的报警，经过对比测试确认是Flutter的bug所致；flutter/flutter#68490 （对比1.25.0-8.1.pre版本已修复，从github的issues中得知，有其它开发着反馈1.24.0-6.0.pre已修复；该问题依赖Flutter升级修复）
