queen_validators package
provider validation rules from queen_validators package

example #
class GoodDto {
@MinLength(5)
@MaxLength(200)
final String name = 'queen';

@MinLength(5)
@MaxLength(200)
final String address = 'kingdom palace';

@IsEmail()
final String email = '[email protected]';
}

final failedRules = validateDto(GoodDto());
if(failedRules.isEmpty){
// * the dto passed the validation successfully
}else{
// * the dto has one or more failed rules
failedRules.forEach(print);
// the result will be formatted like this in case of any failed rules
/// '`$fieldName ${rule.errorMsg}'`
/// email failure
/// '`email is not valid email address'`
