sane_uuid

A properly designed, efficient UUID library for Dart.

• Supports v1, v4, v5 and v6 generation
• Immutable Uuid type with equality, comparison and accessors for properties defined by RFC 4122
  • The internal representation of the UUID is a byte array, not a String
• Support for all syntactically correct UUIDs (regardless of RFC4122 semantics)

Usage

A simple usage example:

import 'package:sane_uuid/uuid.dart';

// randomly generated using secure random number generator
final Uuid randomUuid = Uuid.v4();
// Prints properly formatted UUID, e.g.: a8796ef4-8767-4cd0-b432-c5e93ba120df
print(randomUuid);

// parse any common UUID string
final parsedUuid = Uuid.fromString(
  'a8796ef4-8767-4cd0-b432-c5e93ba120df',
);

// hyphens and capitalization don't matter
final parsedUuidDifferentFormatting = Uuid.fromString(
    'A8796EF487674CD0B432C5E93BA120DF',
);

// UUID objects with the same data are actually equal
assert(parsedUuid == parsedUuidDifferentFormatting);
