minted_contact

Email addresses and phone numbers as well-modelled value types.

Part of the minted family: pure-Dart value types built on parse, don't validate, so the parser is the only door in and anything that came through it is well-formed by construction. Once you hold an Email, it is a valid email.

Install

dart pub add minted_contact

minted comes with it, holding the vocabulary a parse hands back (ParseOutcome, MintedFailure), and so does minted_constraints for the primitives this package's getters return. Nothing here drags in another domain's engine.

What's in the box

Both check the real standard rather than a shape: the full RFC 5322 grammar, and phone metadata per region. PhoneNumberType is re-exported, so reading phone.type doesn't mean importing the engine behind it.

A quick taste

final email = Email.tryParse('Jane.Doe@Example.COM')!;
email.value;      // 'Jane.Doe@example.com'   (domain lower-cased for you)
email.domain;     // 'example.com'
email.mailtoUri;  // mailto:Jane.Doe@example.com

Email.tryParse('not-an-email');   // null, nothing thrown

// the domain is a String because it isn't always a hostname (address literals, IDNs):
email.domainAsHostname().getOrNull();   // Hostname('example.com'), null for those

// PhoneNumber normalises to E.164. National-format input takes a region hint;
// international ('+…') input doesn't:
final phone = PhoneNumber.tryParse('0 655 5705 76', region: 'FR')!;
phone.value;   // '+33655570576'
phone.type;    // PhoneNumberType.mobile
phone.telUri;  // tel:+33655570576

PhoneNumber.tryParse('0 655 5705 76');   // null, no region given

The runnable version is the example. Email.domainAsHostname is why this package carries minted_network too.

One shape, every type

• Type.tryParse(input) hands back the value, or null when the input isn't valid
• Type.parse(input) hands back a ParseOutcome: the value, or a typed failure (EmailFailure, PhoneNumberFailure) you can switch on, or read as a form-field message via .reasonOrNull. No door throws
• value equality, a canonical .value normalised on parse, and fromComponents for parts you already hold

The minted README is the family guide: the package index, handling failures, and the one caveat (never cast into a minted type).
