cnpj_cpf_helper_nullsafety

Description:

cnpj cpf helper nullsafety

Fork from, cnpj_cpf_helper, to null safety.
This library helps with CNPJ and CPF validations. Both of them are brazilian a documentation where CNPJ is a business document and CPF is a person document.
Usage #
A simple usage example:
import 'package:cnpj_cpf_helper_nullsafety/cnpj_cpf_helper_nullsafety.dart';

void main() {
// generate a random cnpj
var _cnpj = CnpjCpfBase.randomCnpj(withMask: true);
print('a random CNPJ: $_cnpj');

// masking a cnpj
var _fromCnpj = '26954374000130';
_cnpj = CnpjCpfBase.maskCnpj(_fromCnpj);
print('masking a CNPJ, from this: $_fromCnpj to this: $_cnpj');
// it's possible to masking partially
_fromCnpj = '2695437';
_cnpj = CnpjCpfBase.maskCnpj(_fromCnpj);
print('masking partially a CNPJ, from this: $_fromCnpj to this: $_cnpj');

// unmasking a cnpj
_fromCnpj = '03.451.682/0001-47';
_cnpj = CnpjCpfBase.onlyNumbers(_fromCnpj);
print('unmasking a CNPJ, from this: $_fromCnpj to this: $_cnpj');

// validate a cnpj
// there are two kinds of validation
// the first one (the simplest one) just returns a bool value
if (CnpjCpfBase.isCnpjValid(_cnpj)) {
print('$_cnpj is a valid CNPJ');
}

// the second one returns a enum that describe the status
_cnpj = '48.608.581/0005-00'; // invalid digit
var _status = CnpjCpfBase.cnpjValidate(_cnpj);
switch (_status) {
case EDocumentStatus.DIGIT:
print('CNPJ\'s digit is wrong!');
break;
case EDocumentStatus.FORMAT:
print('CNPJ\'s format is wrong!');
break;
case EDocumentStatus.EMPTY:
print('CNPJ is empty!');
break;
default:
print('$_cnpj is a valid CNPJ');
}

// generate a random cpf
var _cpf = CnpjCpfBase.randomCpf(withMask: true);
print('a random CPF: $_cnpj');

// masking a cpf
var _fromCpf = '89638567040';
_cpf = CnpjCpfBase.maskCpf(_fromCpf);
print('masking a CPF, from this: $_fromCpf to this: $_cpf');
// it's possible to masking partially
_fromCpf = '89638567';
_cpf = CnpjCpfBase.maskCpf(_fromCpf);
print('masking partially a CPF, from this: $_fromCpf to this: $_cpf');

// unmasking a cpf
_fromCpf = '510.867.680-86';
_cpf = CnpjCpfBase.onlyNumbers(_fromCpf);
print('unmasking a CPF, from this: $_fromCpf to this: $_cpf');

// validate a cnpj
// there are two kinds of validation
// the first one (the simplest one) just returns a bool value
if (CnpjCpfBase.isCpfValid(_cpf)) {
print('$_cpf is a valid CPF');
}

// the second one returns a enum that describe the status
_cpf = '';
_status = CnpjCpfBase.cpfValidate(_cpf);
switch (_status) {
case EDocumentStatus.DIGIT:
print('CPF\'s digit is wrong!');
break;
case EDocumentStatus.FORMAT:
print('CPF\'s format is wrong!');
break;
case EDocumentStatus.EMPTY:
print('CPF is empty!');
break;
default:
print('$_cpf is a valid CPF');
}
