PostalCodePattern class abstract Extensibility

A pluggable postal-code validation strategy.

Implement this class to plug country-specific postal-code validation into VString.postalCode. The core ships with UsZipPattern, CaPostalCodePattern and UkPostcodePattern. External packages (e.g. validart_br with CEP) can add more.

class BrCepPattern extends PostalCodePattern {
  const BrCepPattern();

  @override
  String get name => 'CEP';

  @override
  bool matches(String value) =>
      RegExp(r'^\d{5}-?\d{3}$').hasMatch(value);
}

V.string().postalCode(patterns: [const BrCepPattern()]);

See also:

• VString, which consumes patterns through its postal-code validator.
• UsZipPattern, CaPostalCodePattern and UkPostcodePattern, the built-in implementations.
