Evaluate returns double instead int

When the number greater then 2147483647 in Dart I get double value.

Example:

2147483647 (JS) -> 2147483647 (Dart)
2147483648 (JS) -> 2147483648.0 (Dart)

In quickjs, integer larger than 2147483647 is stored in double
please see https://262.ecma-international.org/5.1/#sec-8.5
and https://bellard.org/quickjs/quickjs.html#Numbers

It may make sense to somehow change this behavior, because it is logical that the int in Javascript is compatible with int in Dart? It turns out that depending on the size of the number, we have to interpret the result differently.

For example: If the user is using the package built_value then this behavior creates problems (I know how to solve it with built_value, but it is unexpected behavior).

I do not know what behavior you want. Is there any problem that using num type in package built_value?

Currently type wrapper cannot tell whether the passed js float point value is integer or not.
