Answer 1

Try below code hope its help to you.

Your var declaration:

double price = 109.95; 

Your Widget:

Using String Interpolation:

    Text(
        'Price: $price',
      ),

OR Using toString():

  Text(
         price.toString() ,
      ),

Result Screen->

Answer of @Ravindra is correct but you need to fix your model.

First, change price type to double

Second, change

price: json['price']

to

price: (json['price'] as num)?.toDouble()
