Random abstract class

A generator of random bool, int, or double values.

The default implementation supplies a stream of pseudo-random bits that are not suitable for cryptographic purposes.

Use the Random.secure() constructor for cryptographic purposes.

Constructors

Random([int seed ])
factory

Creates a random number generator.

Random.secure()
factory

Creates a cryptographically secure random number generator.

Properties

hashCodeint
read-only, inherited

The hash code for this object.

runtimeTypeType
read-only, inherited

A representation of the runtime type of the object.

Operators

operator ==(other) → bool
inherited

The equality operator.

Methods

nextBool() → bool

Generates a random boolean value.

nextDouble() → double

Generates a non-negative random floating point value uniformly distributed in the range from 0.0, inclusive, to 1.0, exclusive.

nextInt(int max) → int

Generates a non-negative random integer uniformly distributed in the range from 0, inclusive, to max, exclusive.

noSuchMethod(Invocation invocation) → dynamic
inherited

Invoked when a non-existent method or property is accessed.

toString() → String
inherited

Returns a string representation of this object.
