Flutter导航管理插件galli_navigation的使用

galli_navigation 是一个Flutter插件，它通过添加导航功能扩展了Galli Vector插件。该插件允许你使用来自Galli Maps的矢量地图进行导航，并提供了路线计算和逐段导航等功能。

功能

• 逐段导航
• 多种方法（步行/驾驶/骑行）的路线计算
• 实时导航更新

安装

在 pubspec.yaml 文件中添加 galli_navigation：

dependencies:
  galli_navigation: latest

然后运行 flutter pub get 来安装新的依赖项。

使用

在Dart代码中导入插件：

import 'package:galli_navigation/galli_navigation.dart';

基本示例

以下是一个简单的使用 galli_navigation 插件的示例：

初始化galli_methods

/// 初始化galli_methods
GalliMethods methods = GalliMethods("authToken");

使用经纬度进行导航

/// 设置起点和终点
LatLng source = LatLng(latitude, longitude);
LatLng destination = LatLng(latitude, longitude);

/// 使用经纬度进行导航
methods.navigateWithLatLng(
  context: context,
  source: source,
  destination: destination,
  method: RoutingMethods.driving,
);

使用导航数据进行导航

/// 获取导航数据
var navJson = await methods.getNavigationData(
  source: source,
  destination: destination,
  method: RoutingMethods.walking,
);

/// 解析导航数据
NavigationModel navData = NavigationModel.fromJson(navJson["routes"].first);

/// 使用解析后的导航数据进行导航
methods.navigate(
  context: context,
  navData: navData,
  method: RoutingMethods.driving,
);
