ID Generators

The standartized, easy-to-use and well-tested set for generate identifiers: globally unique, readable, time-dependency, transitive, incremental, decremental IDs. Feel free to use it in your projects.

Usage

Generate 4 UUIDs

About UUID (online generator): https://uuidgenerator.net

for (var i = 0; i < 4; ++i) {
  print(genUuid);
}

Output:

490833da-4976-4563-8c8a-9f5464a2bf7e
e82e3bf5-c3ea-46d6-a835-12644b99cf6e

Generate HID from language

Supported languages:

• Belarusian
• English
• Ukrainian

const gen = HumanIdGen(options: HumanIdGenOptions(lowerCase: true));
final hid = gen.get('Тема статті чи назва курсу');
print(hid);

Output:

tema-stati-chy-nazva-kursu

Generate Transit Integer ID

print(genTransitId);
// or
print(TransitId().next);

Output:

1
2

Generate Time Integer ID

print(genTimeId);
// or
print(genTimeIdMicro);

Output:

1705954581187
1705954581188687

Note that second ID does not fit into 53 bits (the size of a IEEE double). A JavaScript number is not able to hold this value.

Add HID and UID to Any Class

class Quant with HasStringIdMix {
  Quant({String? hid, String? uid}) {
    this.hid = hid;
    this.uid = uid;
  }
}

print(Quant().id);
print(Quant(hid: 'aerwyna').id);

Output:

92e6ee3e-537a-4dd3-b4e9-06b8fd366469
aerwyna
