A value of type 'Object?' can't be assigned to a variable of type 'Map'. Its a Routing error

Question

The error is when I try to use the ModalRoute.of(context).settings.arguments I get an error. Also I want to save it in a map but can't.

Map data = {};
data = ModalRoute.of(context).settings.arguments; // this is the error;

Error: A value of type 'Object?' can't be assigned to a variable of type 'Map<dynamic, dynamic>'.

• 'Object' is from 'dart:core'.
• 'Map' is from 'dart:core'. data = ModalRoute.of(context).settings.arguments;

Answer 1

After passing so many problems, finally, the solution is surprisingly easy.

Map data = {};
data = ModalRoute.of(context).settings.arguments as Map; 

Answer 2

Try using:

data=ModalRoute.of(context)?.settings?.arguments as Map;

The ? is used for null safety

Answer 3

after lot of searching this coda works

Map data = {};
data = ModalRoute.of(context)?.settings.arguments as Map;

Answer 4

You can do that with the below code:

Map <String, Object>data = {}; // as the arguments passed from 
data = {"dataKey":ModalRoute.of(context).settings.arguments};

And later, access your arguments by calling

data["dataKey"] // it will return the arguments

I was facing a similar issue and I think this solution will help you

Map data = ModalRoute.of(context)!.settings.arguments as Map;

Answer 6

Put the below code inside of your StatefulWidget class

Map userdata = {};
userdata = ModalRoute.of(context)!.settings.arguments as Map;
print(userdata);

Your output looks like something this

flutter: {firstName: Dhaval, lastname: Gevariya}

Answer 7

1. Define the argument Like :

   class ProductDetailsArguments { final Product product;

   ProductDetailsArguments({required this.product});

   }

2. extracts the arguments Like

   final args = ModalRoute.of(context)!.settings.arguments as ProductDetailsArguments;

Answer 8

To solve the issue, I did :

Map <String, dynamic> data = {}; data = ModalRoute.of(context).settings.arguments as Map<String, dynamic>;
