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
- 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.
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. [...]
Operators
- operator ==(
Object other) → bool inherited - The equality operator. [...]
