I encountered an error when using mapbox_maps_flutter.

まだ誰も着手していません。

When I am conducting real-device debugging with Flutter on a mobile phone running the HarmonyOS 4.2.0 system, the native channel always fails to be established, resulting in the failure of Mapbox.

HarmonyOS 4.2.0を実行している実機で失敗を再現し、package:mapbox_maps_flutter/src/pigeons/map_interfaces.dart の6246行目と、Flutterのplatform-channelおよびplatform-viewのエラーから開始します。ネイティブチャネルとplatform-viewの登録が失敗するかを追跡します。報告された2つのPlatformExceptionのどちらも発生せずにマップが初期化されれば完了です。
