Java 用flatter打开谷歌定位

我想在android上用我的Flitter应用程序从WhatsApp location打开google locations，并获取[纬度，经度]数据在地图上绘制

我试过这个

在android.manifest.xml中

最后

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="geo" />
</intent-filter>

public class MainActivity extends FlutterActivity {

  private String sharedText;
  private static final String CHANNEL = "app.channel.shared.data";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    String type = intent.getType();
    String action = intent.getAction();

    if (Intent.ACTION_VIEW.equals(action) && type != null) {
      handleSendText(intent);
    }
  }

  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);

    new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), CHANNEL)
            .setMethodCallHandler(
                    (call, result) -> {
                      if (call.method.contentEquals("getSharedText")) {
                        result.success(sharedText);
                        sharedText = null;
                      }
                    }
            );
  }

  void handleSendText(Intent intent) {
    sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
  }
}

  void getSharedText() async {
    var sharedData = await platform.invokeMethod("getSharedText");
    if (sharedData != null) {
      setState(() {
        dataShared = sharedData;
      });
    }
  }
