|
||
|
||
基于[高德开放平台地图SDK](https://lbs.amap.com/api/)的flutter插件
|
||
|
||
## Usage
|
||
使用Flutter插件，请参考[在Flutter里使用Packages](https://flutter.cn/docs/development/packages-and-plugins/using-packages), 添加amap_map的引用
|
||
|
||
## 准备工作
|
||
* 登录[高德开放平台官网](https://lbs.amap.com/)申请ApiKey。Android平台申请配置key请参考[Android获取key](https://lbs.amap.com/api/poi-sdk-android/develop/create-project/get-key/?sug_index=2), iOS平台申请配置请参考[iOS获取key](https://lbs.amap.com/api/poi-sdk-ios/develop/create-project/get-key/?sug_index=1)。
|
||
* 引入高德地图SDK，Android平台请参考[Android Sudio配置工程](https://lbs.amap.com/api/android-sdk/guide/create-project/android-studio-create-project), iOS平台请参考[ios安装地图SDK](https://lbs.amap.com/api/ios-sdk/guide/create-project/cocoapods)
|

|
||
## 使用示例
|
||
``` Dart
|
||
import 'package:amap_map_example/base_page.dart';
|
||
import 'package:flutter/material.dart';
|
||
|
||
import 'package:amap_map/amap_map.dart';
|
||
import 'package:x_amap_base/x_amap_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<StatefulWidget> createState() => _ShowMapPageState();
|
||
}
|
||
|
||
class _ShowMapPageState extends State<_ShowMapPageBody> {
|
||
static final CameraPosition _kInitialPosition = const CameraPosition(
|
||
target: LatLng(39.909187, 116.397451),
|
||
zoom: 10.0,
|
||
);
|
||
@override
|
||
Widget build(BuildContext context) {
|
||
final AMapWidget map = AMapWidget(
|
||
initialCameraPosition: _kInitialPosition,
|
||
onMapCreated: onMapCreated,
|
||
);
|
||
|
||
return ConstrainedBox(
|
||
constraints: BoxConstraints.expand(),
|
||
child: Container(
|
||
height: MediaQuery.of(context).size.height,
|
||
width: MediaQuery.of(context).size.width,
|
||
child: map,
|
||
),
|
||
);
|
||
}
|
||
|
||
AMapController _mapController;
|
||
void onMapCreated(AMapController controller) {
|
||
setState(() {
|
||
_mapController = controller;
|
||
});
|
||
}
|
||
|
||
}
|
||
|
||
```
|
||
|
||
## 已知问题
|
||
1. [android] app 的 targetSDKVersion >= 30, 地图页返回闪退
|
||
|
||
在里的AndroidManifest.xml里的application里增加`android:allowNativeHeapPointerTagging="false"`
|
||
```xml
|
||
<application android:allowNativeHeapPointerTagging="false">
|
||
...
|
||
</application>
|
||
```
