鸿蒙Flutter实战:19-Flutter集成高德地图,跳转页面方式

前言

在之前的文章现有Flutter项目支持鸿蒙II中,介绍了如何使用第三方插件,同时给出了非常多的使用案例,如
flutter_inappwebview,video_player, image_picker 等,本文将开始介绍如何集成高德地图。

整体方案

通过 MethodChannel 进行消息通信,在 Dart 侧调用原生API,在 ArkTS 侧收到相关调用后,根据参数跳转到指定页面

Dart 侧

  static Future<dynamic> redirectNative(String url) {
    return _methodChannel.invokeMethod("redirectNative", {
      "url": url,
    });
  }

ArkTS 侧

ohos/entry/src/main/ets/entryability 创建 OhosPlugin.ets 文件,这里收到到消息后,调用 router.pushUrl 方法跳转到指定页面

export default class OhosPlugin implements FlutterPlugin {
  ...
  onAttachedToEngine(binding: FlutterPluginBinding): void {
    this.channel.setMethodCallHandler({
      onMethodCall : (call: MethodCall, result: MethodResult) => {
        switch (call.method) {
          case "redirectNative":
            let url = String(call.argument("url"));
            router.pushUrl({ url: url})
            break;
          default:
            result.notImplemented();
            break;
        }
      }
    })
  }
}

插件写好后,需要在 EntryAbility 中注册:

this.addPlugin(new OhosPlugin())

添加原生页面,回到 DevEco,在 pages 目录右键,创建一个空页面, 命名为 Amap

ohos/entry/oh-package.json 文件中引入高德地图SDK:

  "dependencies": {
    "@amap/amap_lbs_common": ">=1.1.0",
    "@amap/amap_lbs_map3d": ">=2.1.1",
    ...
  }

调用高德地图SDK,显示地图组件:

import { AMap, MapsInitializer, MapView, MapViewComponent, MapViewManager, } from '@amap/amap_lbs_map3d';
// 配置 API KEY
MapsInitializer.setApiKey("xxx");
MapViewManager.getInstance().registerMapViewCreatedCallback((mapview?: MapView, mapViewName?: string) => {
  if (!mapview) {
    return;
  }
  let mapView = mapview;
  mapView.onCreate();
  mapView.getMapAsync((map) => {
    let aMap: AMap = map;
  })
})

@Entry
@Component
struct Index {
  build() {
    Row() {
      MapViewComponent()
        .width('100%')
        .height('100%')
    }
  }
}

调用

PlartformCall.redirectNative('pages/Amap');

注意事项

如果在运行时,遇到以下错误, 根据官方提醒, 需要配置 useNormalizedOHMUrl

 ERROR: Bytecode HARs: [@amap/amap_lbs_map3d, @amap/amap_lbs_common] not supported when useNormalizedOHMUrl is not true.

打开文件 /ohos/build-profile.json5, 添加以下配置

 		{
 		  "app": {
 		    "products": [
 		      {
 		         "buildOption": {
 		           "strictMode": {
		             "useNormalizedOHMUrl": true
 		           }
 		         }
 		      }
 		    ]
 		  }
 		}
