amap_flutter_map

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:

<key>io.flutter.embedded_views_preview</key>
<string>YES</string>

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）
