In the provider model I use context after await It shows warning Do not use BuildContexts across async gaps and I am unable to check with mounted because I use it in Provider class. so what I should do to remove this warning? Any help would be appreciated thanks.

class SoloStartSiteScanningProvider extends ChangeNotifier {
  FocusNode boxFocusNode = FocusNode();
  FocusNode locationFocusNode = FocusNode();
  Future checkBoxSealMatching(BuildContext context) async {
    try {    
      var barcode = await _scanBoxBarcode();
      if (barcode != "-1") {
        if (boxFieldController.text == barcode) {
          // Do not use BuildContexts across async gaps
          FocusScope.of(context).requestFocus(locationFocusNode);
        }
      }
    } catch (e) {
      print(" coll lactaion scanning Exception=== $e");
    }
  }
}
