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
- hashCode → int
read-only, inherited
-
The hash code for this object.
- runtimeType → Type
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.
