Guid class final

Represents a globally unique identifier (GUID), a 128-bit value used to uniquely identify entities such as COM interfaces, class objects, and entry-point vectors (EPVs).

A GUID is typically represented as a 36-character string in the format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where each x is a hexadecimal digit.

Structure:

• 8 hex digits (32 bits)
• 4 hex digits (16 bits)
• 4 hex digits (16 bits)
• 4 hex digits (16 bits)
• 12 hex digits (48 bits)

Example: 6b29fc40-ca47-1067-b31d-00dd010662da

Constructors

Guid(int data1, int data2, int data3, Uint8List data4)

Creates a Guid from its raw binary components.

const

Guid.fromBytes(Uint8List bytes)

Creates a Guid instance from a 16-byte little-endian binary encoding.

factory

Guid.fromString(String guid)

Parses a Guid from a string in the canonical format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

factory

Guid.generate()

Generates a new GUID using a cryptographically secure random number generator.

factory

Guid.zero()

Creates a zero-initialized GUID (00000000-0000-0000-0000-000000000000).

Properties

data1 → int

The first 8 hexadecimal digits of the GUID.

final

data2 → int

final

data3 → int

The second group of 4 hexadecimal digits.

final

data4 → Uint8List

The last 8 bytes of the GUID.

final

hashCode → int

The hash code for this object.

no setter, override

isZero → bool

Whether the GUID is a zero-initialized GUID.

no setter

runtimeType → Type

A representation of the runtime type of the object.

toBytes() → Uint8List

Available on Guid, provided by the GuidExtension extension

Converts the Guid into its standard 16-byte little-endian binary representation.

toString() → String

Converts the GUID into its canonical string representation: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

Operators

operator ==(Object other) → bool

The equality operator.
