Dart numbers can be classified as: The int data type is used to represent whole numbers. The double data type is used to represent 64-bit floating-point numbers. The num type is an inherited data type of the int and double types .
Read moreWhat does int mean in Dart?
In the Dart programming language, an integer is represented by the int keyword. As we may know, integers include whole numbers (i.e., non-decimal positive and negative numbers). For every integer, four bytes are allocated in the memory.

int class Null safety. An integer number . The default implementation of int is 64-bit two’s complement integers with operations that wrap to that range on overflow. Note: When compiling to JavaScript, integers are restricted to values that can be represented exactly by double-precision floating point values.

Declaring Variables In Dart Variables are declared using the var keyword followed by variable name that you want to declare . Dart is a type inferred language, which allows compiler automatically infer(know) the type of data we want to store based on the initial value we assign.

Numbers come in two flavors in Dart: integers of arbitrary size and decimal 64 bit doubles as specified by the IEEE 754 standard. Both int and double are subinterfaces of num. num is the supertype, int and double extend num. The num interface defines the basics like +, -, /, and *.

var random = Random(); var n1 = random. nextInt(16); var n2 = random. nextInt(15); if (n2 >= n1) n2 += 1; This ensures that the first number can assume all 16 values, and the second number can assume any of the remaining 15 values, and with as even a distribution as the random generator allows.

The doubles() method of Random class returns a stream of pseudorandom double values, each conforming between zero and one . The second syntax effectively returns an unlimited stream of pseudorandom double values, each conforming to the given randomNumberOrigin and randomNumberBound.
