I’m receiving data from an API that provides a weather info, for simplicity i will provide just an attribute of the received data:

final double feels_like;

and in json deserialization:

feels_Like = json['main']['feels_like']

But i got that Exception : type 'int' is not a subtype of type 'double', actually i solved it (using toDouble()) no problem here, the problem is in the following concept.

Suppose the returned value is an int, can’t a double hold it?

for example:

double feels_like = 30.1; // ok
double feels_like = 30; // also ok

Both data types are sub types of base num class and a double object can holds an int object but not vice versa.

So, Why is that happening while working with the API even if it returns an int.
