nanoid2 2.1.0

A tiny, secure, URL-friendly, unique string ID generator, nanoid with a pure Dart API.

Changelog

2.1.0

• New Alphabet.crockfordBase32, Crockford's Base32, for ids a human reads out loud or types back in. Drops the lookalikes I L O, and U so ids are less likely to spell words (32 chars) #5

  nanoid(alphabet: Alphabet.crockfordBase32, length: 26); // F6J399SP385YMNBFMNEA1YB2YW
  

• New Alphabet.base58, as used by Bitcoin and IPFS. Drops the lookalikes 0 O I l and stays case sensitive, so it is shorter than Base32 at the same entropy (58 chars) #5

  nanoid(alphabet: Alphabet.base58, length: 22); // yKBEBzwwHC7pygkBPJkW52
  

• New Alphabet.cookieSafe, valid in a cookie value without quoting or escaping (77 chars) #5

• Fix The length ArgumentError messages named the wrong bounds, calling 2 and 255 invalid when both generate ids #3

• Fix repository pointed at the repository's old name, so pub.dev could not verify it. Added issue_tracker

• The README gained a Which alphabet? table listing every alphabet with its entropy per character #5, and a Collisions section that charts how many ids each alphabet and length is good for #7

2.0.0

Official Dart 3 support, breaking changes, and new Alphabet API.

Breaking changes:

• nanoid(10) is now nanoid(length: 10). The length parameter has been changed from an optional positional to an optional named parameter.
• The async API import 'package:nanoid/async.dart'; has been removed. Call await Future(() {}); or before calling nanoid() to achieve the same effect.
• Changed package name from import 'package:nanoid/nanoid.dart'; to import 'package:nanoid2/nanoid2.dart';
• The insecure API import 'package:nanoid/non-secure.dart'; has been removed. Call nanoid(random: Random()); instead to force a non-secure (and faster) random number generator. nonoid() automatically uses Random() instead of Random.secure() on platforms that do not provide a cryptographically secure source of random numbers.
• Removed the customAlphabet('custom', 10) API. Use nanoid(alphabet: 'custom', length: 10); instead.

New APIs:

• The Alphabet class provides a set of predefined alphabets for various use cases.

1.0.0
