Not working when start Flutter Engine with FlutterFragment

## 🐛 Bug Report

Maybe method startListening() not being called when I start flutter engine with FlutterFragment. Because doesn't fired on onAttachedToActivity(@NonNull ActivityPluginBinding binding)?
So I getting this exception when trying to check permission: MissingPluginException(No implementation found for method checkPermissionStatus on channel flutter.baseflow.com/permissions/methods).
### Expected behavior

### Reproduction steps
When I call :
final PermissionStatus statusFuture = await PermissionHandler()
.checkPermissionStatus(PermissionGroup.contacts);
I getting this error:
