OtpCodeLetterSet enum

Which alphabet of characters is accepted by the OtpCodeVerificationField.

Some values are letters-portion sets that combine with OtpCodeType to add digits (aToZ, unicodeLetters, custom). Others are self-contained alphabets that imply both digits and letters and constrain OtpCodeType (binary, crockford, hexadecimal, base62, all). See the "Compatibility (asserts at construction)" section in the OtpCodeVerificationField class doc for the full rules.

Values

aToZ → const OtpCodeLetterSet

English ASCII letters: a-z and A-Z (26 letters).

unicodeLetters → const OtpCodeLetterSet

Any Unicode letter (Greek, Cyrillic, CJK, etc.).

all → const OtpCodeLetterSet

Any character accepted by Dart.

crockford → const OtpCodeLetterSet

Crockford alphabet: 'ABCDEFGHJKMNPQRSTVWXYZ0123456789' which is base32 without the easily-confused chars 0/O and 1/I/L. See: https://www.crockford.com/base32.html Note: A better way to implement this is for you to allow OtpCodeLetterSet.aToZ plus OtpCodeType.numbersAndLetters plus OtpCodeLetterCasing.uppercase, and then you'd get the resulting code and convert O to 0, and I/L to 1.

binary → const OtpCodeLetterSet

Only 0 and 1, for binary codes.

hexadecimal → const OtpCodeLetterSet

Digits 0-9 and letters A-F/a-f.

base62 → const OtpCodeLetterSet

Base62 alphabet: digits 0-9, plus letters A-Z and a-z (62 chars). Useful for short URL-safe codes. Pair with OtpCodeLetterCasing.mixed to keep both cases distinct.

custom → const OtpCodeLetterSet

Only chars specified by the OtpCodeVerificationField.customSet. If you specify this, you MUST provide a customSet string with the allowed characters, or you'll get an error.
