Validators 🌍

Usage

if you need

• simple true of false function to validate a input
• validate a normal flutter Form field

@override
Widget build(BuildContext context) {
return TextFormField(
     // use qValidator function and provider list of rules to apply on this field
    validator: qValidator([
      IsRequired(),
      IsOptional()
      IsEmail(),
      MinLength(8),
      MaxLength(30, "optionally you can override the failure if the validation fails"),
    ]),
  );
  }

customization

if you need to show a custom error message you can

• use the rule constructor (scooped for a single rule)
• use ValidatorsLocalization.on (scooped for the entire Type rules)

void main() {
    ValidatorsLocalization.on<IsRequired>((rule) => 'the new required message');
}

• if you use queen all the rules are localized out of the box 🎁 !
