Random 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.

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
A string representation of this object. [...]
