一、背景
flutter项目中有去调用其他第三方地图应用的关键字的路线搜索功能，故此做一个总结。
二、使用
1、添加插件：
url_launcher: ^5.4.2
2、iOS 配置 info.plist
<key>LSApplicationQueriesSchemes</key><array><string>iosamap</string><string>qqmap</string><string>baidumap</string></array>
3、编写工具类
说明一下，通过关键字去搜索地图路线的功能测试已经可以了，地图打开优先级：高德>百度>腾讯>IOS地图，安卓浏览器打开高德h5网页。通过经纬度去进行路线导航，在百度地图中导航需要将高德地图的经纬度转行成百度的经纬度才能使用，转换的逻辑需要自己处理。
