这里介绍的是不需要自己开发地图,直接通过给定的经纬度,跳转到三方地图APP调用导航的方式一种是写的工具类,一种是通过调用三方库
map_launcher
实现的

Flutter 跳转地图软件调起导航:百度、高德、腾讯、苹果
Flutter 实战调起三方地图导航(高德、百度、腾讯、苹果)
插件:
map_launcher
flutter_map
maps_launcher
实现
在 pubspec.yaml 文件中添加依赖插件:
c
# url打开工具 https://pub.flutter-io.cn/packages/url_launcher
url_launcher: ^6.1.14
# 打开地图工具 https://pub.flutter-io.cn/packages/map_launcher
map_launcher: ^2.5.0+1
