An arbitrarily large integer.
Note: When compiling to JavaScript, integers are implemented as JavaScript numbers. When compiling to JavaScript, integers are therefore restricted to 53 significant bits because all JavaScript numbers are double-precision floating point values. The behavior of the operators and methods in the int class therefore sometimes differs between the Dart VM and Dart code compiled to JavaScript.
It is a compile-time error for a class to attempt to extend or implement int.
