Type casting in model.fromJson map

[kidusdev]

Sale.fromJson(s)

factory Sale.fromJson(Map json) => Sale(
        id: json['id'],
        quantity: json['quantity'],
        // eg. quantity: double.tryParse("${json['quantity']}") 
       // this way it can convert String, int, num to double so you don't have to worry about the api data type 
        unitPrice: json['unit_price'],
        createdAt: switch (json['created_at']) {
          DateTime value => value,
          String value => DateTime.parse(value),
          _ => json['created_at']
        },
      );

in this example the Map json data is coming from an api but the quantity is either double or int but the model's quantity field only accepts double. can we parse and cast it to double or are there any other available methods to deal with. i could cast every field but it would be if we have this feature inside the model instead of all over my project

I am waiting for the official release of macros. Previously, FromJson and ToJson relied on code generate.
