return TRTCCloudVideoView(
      key: const ValueKey("_bigVideoViewId"),
      viewType: TRTCCloudDef.TRTC_VideoView_TextureView,
      onViewCreated: (viewId) async {
        controller.bigVideoViewId = viewId;
        controller.openCamera();
      },
    );


  Future startCapturePicture() async {
    String path = Services.system.getCacheFilePath(
        "${Utils.getNowTimeFmt(Utils.yyyyMMddhhmmssSSS)}.jpg");

    final Completer _completer = Completer();

    void _listener(type, params) {
      if (type == InterviewEvent.onSnapshotComplete) {
        _completer.complete(params);
      }
    }

    _interview.registerListener(_listener);
    await _interview.mTRTCCloud
        .snapshotVideo(null, TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_BIG, path);
    final result = await _completer.future;
    _interview.unRegisterListener(_listener);

    if (result["errCode"] == 0) {
      bool find =
          await HmCameraViewController.shared.findFace(result["path"]) ?? false;
      if (find) {
        Get.showNotice(message: "find face");
      } else {
        Get.showNotice(message: "not find face");
      }
    }
    Log.d("$result");
  }
}

调用startCapturePicture() 程序崩溃
