A value of type 'Object?' can't be assigned to a variable of type 'Map<dynamic, dynamic>'. Its a Routing error
Solution 1:
After passing so many problems, finally, the solution is surprisingly easy.
Map data = {};
data = ModalRoute.of(context).settings.arguments as Map;
Solution 2:
Try using:
data=ModalRoute.of(context)?.settings?.arguments as Map;
The ? is used for null safety
