int
Integer values no larger than 64 bits.

double
64-bit (double-precision) floating-point numbers.

Both int and double are subtypes of num. The num type includes basic operators such as +, -, /, and *, and is also where you’ll find abs(), ceil(), and floor(), among other methods.

  // String -> int
  var one = int.parse('1');
