CodePudding user response：

You are assigning PointdeVente object to bool object

I think you're using like this

bool? result = await Navigator.of(context).pushNamed(YourScreen.route):

and in YourScreen you pop like this

Navigator.pop(context,PointdeVente());

You have to do something like this. Example:

PointdeVente? result = await Navigator.of(context).pushNamed(YourScreen.route):

if you are expecting PointdeVente then you should pop like this in YourScreen

Navigator.pop(context,PointdeVente());
