flutter 高德地图api使用 app内集成定位 地图搜索功能
amap_all_fluttify插件（现在不知道咋的没有了）
这个插件就是集成了amap_map_fluttify amap_search_fluttify amap_location_fluttify三个插件 分别在pubspec里导入就行
main.dart里先注册 获取andriod和ios的相关key
///地图基本功能-注册高德key
await AmapService.init(androidKey: 'xxxxxxx', iosKey: "yyyyyyy");
下面是关键代码
这里是点击选择后的跳转
（ios14有地图定位bug 一旦要定位自己的位置就会报错 所以ios14取消定位自己 只有地图显示 ios13及以下都没有问题 求助高德官方也无果 因为此插件非官方插件）
/*等待返回数据是异步操作*/
void chooseActAddress() async
// final result2 = await Navigator.push(//等待
// context,MaterialPageRoute(builder: (context)=> SelectLocationFromMapPage())
// );
var add = await Navigator.pushNamed(context, '/SelectLocation');
print(add);
Map tmp = add;
provinceName = tmp['provinceName'];
cityName = tmp['cityName'];
provinceName = provinceName.substring(0, provinceName.length - 1);
cityName = cityName.substring(0, cityName.length - 1);
district = tmp['district'];
addressTitle = tmp['title'];
latitude = tmp['latitude'];
longitude = tmp['longitude'];
print("addressTitle" + addressTitle);
if (mounted)
setState(()
textControllerAddress.text = tmp['title'];
);
// print(district);
print(provinceName + cityName);
这里是想要选择地址后的跳转代码
