uuid 4.5.1

RFC4122 (v1, v4, v5, v6, v7, v8) UUID Generator and Parser for Dart

Changelog

v4.5.1

• Add UuidValue.fromNamespace to let you make constant variants of the namespace, as due to language limitations on Enums, Namespace.*.uuidValue can't be constant.
• Added isV#(), isNil(), and isMax() functions to UuidValue for matching Dart standards.

v4.5.0

• Change to CryptoRNG by default, you will now need to use MathRNG explicitly if you want speed over security. (thanks @Rexios80)
  • This also works around a regression in the Dart SDK on WASM targets: https://github.com/dart-lang/sdk/issues/56609
• Deprecate the use of Uuid.NAMESPACE* and UuidV5.NAMESPACE, and switch to using a proper const enum for this. (thanks @bymoye)
  • These will be removed once sufficient time has been made for the deprecation notice to be seen. Most likely v5.0.
  • Please use the new Namespace enum in enums.dart.
• Re-add Uuid.NAMESPACE* and UuidV5.NAMESPACE in order to give deprecation time.
• Add missing MAX UUID option from RFC9562
• Add bytes getter to Namespace enum.
• [PARTIAL BREAKING CHANGE] Namespace is now an enum, and the entries are now of the Namespace type. They all have a value function to return the internal string

v4.4.2

• Revert meta depenency version upgrade, was breaking flutter_test. (thanks @techouse)

v4.4.1

• Fix UUIDv1 to use millisecondsSinceEpoch instead of microsecondsSinceEpoch. Matches UUIDv6 and passes vector tests.

v4.4.0

• Fix MathRNG with Seed being recreated on each use, generating the same list of bytes. (thanks @showband)
• Fix UUIDv5 UTF8 inconsistencies. (thanks @vjamrich)
• Use static state storage for random number generator to prevent MathRNG issue.
• Replace V1, v6, V7, V8 MathRNG preventively, the issue didn't exhibit there due to other factors in the UUID generation (primarily time, and clockseq)

v4.3.3

• Fix UUIDv7 in Javascript
  • Using bitshifts on anything over 32bits get truncated. Switched to a more naive solution for now. Hopefully dart2wasm fixes things.
• Remove unnecessary _randomData() functions
• Add fixnum package to handle issues in v6, time, and javascript.

v4.3.2

• Added toFormattedString() to UuidValue to handle cases where the UUID used has no hyphens but you wnt them for output.
• Changed constraint for meta to 1.10.0 to not conflict with flutter_test

v4.3.1

• Add additional optional parameters for parseing and validation for the new noDashes flag.

v4.3.0

• Update SDK constraints to >= 3.0.0
• Update Meta package to 1.11.0
• [PARTIAL BREAKING CHANGE] Changing MathRNG implementation to use 4 nextints, instead of 16 for optimization to match CryptoRNG. This will affect regenerating the same UUID from the same seed.
  • If you need the old behavior, please use MathRNGDeprecated() instead.

v4.2.2

• Fix CryptoRNG on Web generating a random number 0 always
• Add NoDashes support to the validator so that it validates UUIDs that don't have dashes but are otherwise valid.

v4.2.1

• Lower meta dependency to 1.9.1 so that it is compatible with Flutter Stable 3.13

v4.2.0

• [BREAKING CHANGE] Deprecate default/empty UuidValue constructor because it has a different behavior from the 3.x package version. (Thanks @davidmartos96)
  • Use UuidValue.fromString() instead, which has the same behavior. If you need to define a const UuidValue you can use UuidValue.raw(), but making sure the value is lowercase.
• Mark UuidValue as experimental with an annotation. (Thanks @Kaival-Patel)

v4.1.0

• [BREAKING CHANGE] In order to enforce lowercase strings in UuidValue, I have made the default const constructor private, and added a fromString factory constructor. Please migrate any direct UuidValue() usage to UuidValue.fromString() or UuidValue.withValidation().

v4.0.0

• toBytes on UuidValue now does not validate by default, but has the option validate that can be set to true if you need validation when calling it. (Thanks @Erhannis)

v4.0.0-beta3-1

• Ensure that any custom RNG implementation produces Uint8Lists of length 16. (Thanks @wph44)

v4.0.0-beta3

• [BREAKING CHANGE] Replacing UuidUtil rng functions with RNG classes.
  • UuidUtil.mathRNG() is replaced with MathRNG().generate().
  • UuidUtil.cryptoRNG() is replaced with CryptoRNG().generate().
  • Custom crypto implementations just need to implement the RNG abstract class.
  • namedArgs and positionalArgs have been removed from GlobalOptions
  • You may use LegacyRNG() if you need to use the old function style RNG.
• Fix a bug with the usage of Uint64List in Dart2js by not using it. (Thanks @hambergerpls)

v4.0.0-beta2

• [BREAKING CHANGE] The Uuid class now takes a GlobalOptions class instead of a Map<String, dynamic>.
• Added options classes to eventually replace the Map parameter.
• [BREAKING CHANGE] Since v6,v7,v8 are new for 4.0, I have made it so they only take the new options class.
• Reworked the constructors, and moved state out of the classes. Const is now supported properly again
• Switched tests to use const Uuid to catch regressions.
• Set the options parameter in v1, v4, and v5 to deprecated.
• [BREAKING CHANGE] Make UuidValue properly const also
  • Can no longer run validation on the const variant.
  • Added UuidValue.withValidation() to handle this usecase, it can't be const.
  • If you need const and validation. Create the UuidValue with the UUID, then call the validate() function on it.

v4.0.0-beta1-1

• Mostly cleanup, linting, updating depedencies, etc.

v4.0.0-beta1

• Break up versions into individual objects that can be used standalone.
• No more colliding global states between versions
• Added UUID v6, v7, v8 from the new RFC.
• Add time, version, and variant functions to UuidValue

v3.0.7

• Fixed parse to allow buffers larger than 16 bytes to be used. [Thanks @hoylen]

v3.0.6

• Enable avoid_dynamic_calls linting and fix appropriately. (Thanks @devoncarew)

v3.0.5

• Global options were incorrectly being ignored. #76 (Thanks @Skycoder42)
• V4 Global Options were incorrectly named. #76 (Thanks @Skycoder42)
• Global state was static, not per instance. #76 (Thanks @Skycoder42)
• Additional tests to make sure the above doesn't regress. #76 (Thanks @Skycoder42)

v3.0.4

• isValidUUID now handles some Microsoft GUIDs better that only deviate in the Variant setting. (Thanks @FluentChange)
• Improve error output so that it better explains how to handle the above change in your code if you encounter it. (Thanks @FluentChange)
• Improve validation logic to better handle multiple validation cases, error output, and feedback to developers. (Thanks @FluentChange)

v3.0.3

• [Experimental] Fixed UuidValue to properly check things are valid. (Thanks @FlorianUlivi)
• [Experimental] Added new constructors fromByteList and fromList to UuidValue
• [Experimental] Added == operator override and hashcode override. (Thanks @giorgiofran for suggestion)
• Added parseAsByteList to offer a direct output to Uint8List
• [Experimental][BREAKING CHANGE] Change toBytes in UuidValue to return Uint8List instead of List<int>
• [Experimental][BREAKING CHANGE] isValidUuid function signature has changed, now takes 2 optional parameters fromString and fromList that will do the appropriate validation on different sources.

v3.0.2

• [Experimental] Add flags to UuidValue constructor and parse to disable validation of the UUID, primarily to allow Microsoft GUIDs to not break things.

v3.0.1

• Fix RNG to not need shuffling and improve performance/memory usage (Thanks @julemand101)

v3.0.0

• Release nullsafety version.

v3.0.0-nullsafety.1

• [BREAKING CHANGE] Changed parse() to throw a FormatException instead of returning NIL uuids or partially handled UUIDs.
• Changed Uuid constructor to be constant, and adjusted all the code accordingly.
• New isValidUUID function for validating UUIDs.
• [BREAKING CHANGE] parse and unparse are now static functions.
• [Exprimental] Object version of the UUID instead of a string or list of bytes.
