Usage

See example/main.dart

Standard - I, V, X, L, C, D, M

final ToRoman standardToRoman = ToRoman();

final String roman = standardToRoman(3888);
// roman == 'MMMDCCCLXXXVIII'

final int decimal = standardToRoman.inverse()('MMMCMXCIX');
// decimal == 3999

Unicode - Ⅰ, Ⅴ, Ⅹ, Ⅼ, Ⅽ, Ⅾ, ↀ, ↁ, ↂ

final FromRoman unicodeFromRoman = FromRoman.unicode();

final String roman = unicodeFromRoman.inverse()(38888);
// roman == 'ↂↂↂↁↀↀↀⅮⅭⅭⅭⅬⅩⅩⅩⅤⅠⅠⅠ'

final int decimal = unicodeFromRoman('ↂↂↂↀↂⅭↀⅩⅭⅠⅩ');
// decimal == 39999

romanice-dart's Issues

Null safety

Very slick lib :)
But unfortunately it's not null safe...
Could you enable null safety so I can use it in null safe projects ?
