Uint64 class

Represents a 64-bit unsigned integer.

This class uses Dart's native number type BigInt and has a value check for big integers. BigInt will be translated correctly into JavaScript (supported by dart2js). Value range is 0 through 18446744073709551615.

Implemented types

Comparable<Uint64>

Constructors

Uint64.new([num value = 0, num value2 = 0]): factory

Methods

abs() → Uint64
compareTo(Uint64 other) → int: Compares this object to another object.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toBigInt() → BigInt: Returns this Uint64 as a BigInt.
toBytes() → Uint8List: Converts to 64-bit byte array.
