b - Base conversion

A Dart library for converting between different bases, e.g., decimal ↔ binary, octal ↔ hexadecimal

Usage

See example/main.dart

Hexadecimal ↔ Base58

final BaseConversion hexadecimalToBase58Converter = BaseConversion(
  from: '0123456789abcdef',
  to: base58,
);

final String base58Value = hexadecimalToBase58Converter('415a59758fb933b6049b050a556dd4d916b7b483f6966615');
// base58Value == '6xZA4Qt9vH7rePWeT5WLaVUZNjB6u6rGc'

final String hexadecimal = hexadecimalToBase58Converter.inverse()('GjWGF6jERR9ymrC1bHcGmsJYkLMDoaySr');
// hexadecimal == 'ac93c8d619c76f823f184110759b278f246cc7cc3cadcac3'

Decimal (emoji) ↔ Hexadecimal

final BaseConversion decimalEmojiToHexadecimalConverter = BaseConversion(
  from: '0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣',
  to: base16,
  zeroPadding: true,
);

final String hexadecimal = decimalEmojiToHexadecimalConverter('5️⃣1️⃣9️⃣6️⃣6️⃣');
// hexadecimal == '0CAFE'

final String decimalEmoji = decimalEmojiToHexadecimalConverter.inverse()('DEADC0DE');
// decimalEmoji == '3️⃣7️⃣3️⃣5️⃣9️⃣2️⃣9️⃣0️⃣5️⃣4️⃣'
