### 近期 TODO:
#### Android
- 完善坐标转换
- 添加一些常用的方法

#### iOS
- 完善坐标标转换
- 完善 Cluster（点聚合）
- 添加一些常用的方法

Marker icon 的实现参考了 https://github.com/react-native-community/react-native-maps 的相关代码。

### Dev & Test 开发和测试说明
react-native doesn't support symlinks. see https://stackoverflow.com/questions/44061155/react-native-npm-link-local-dependency-unable-to-resolve-module. Can't install local package by using `npm link`.

react-native 不支持软链，参考：
https://stackoverflow.com/questions/44061155/react-native-npm-link-local-dependency-unable-to-resolve-module
所以不能使用 npm link 的方式安装本地的包


### Environments 环境要求
1.JS
- node: 12+
- react-native: 0.50.+
2.Android
- Android SDK: api 28+
- gradle: 4.10.1
- Android Studio: 3.1.3+

3.iOS
- XCode: 11.3+


### 初始化
#### Android
AndroidManifest.xml 设置

必要的权限

```
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
```

application 下添加名为 com.baidu.lbsapi.API_KEY 的 meta，如

```
<meta-data
        android:name="com.baidu.lbsapi.API_KEY"
        android:value="uDRdqQMGQeoPGn5CwMmIYicdUIVv1YST" />
```

#### iOS
使用 BaiduMapManager.initSDK 方法设置 api key，如
```
import { BaiduMapManager } from 'react-native-baidu-map'
BaiduMapManager.initSDK('sIMQlfmOXhQmPLF1QMh4aBp8zZO9Lb2A');
```
