CPF Utility

A simple package that provides CPF utilities.

A CPF is an 11 digit number which is the Brazilian individual identity number.

Example of a formatted CPF: 321.524.051-37

Usage

To generate a valid CPF simply:

String myCpf = Cpf.generate();

If you want to generate a valid CPF from a given Brazilian state you can use the State enum:

String myCpf = Cpf.generate(state: States.sp);

The CPF comes formatted by default, you can make it unformatted:

String myCpf = Cpf.generate(formatted: false);

If you have an unformatted CPF and want to format it:

String myCpf = Cpf.generate(formatted: false); // 32152405137
String formattedCpf = Cpf.format(myCpf);       // 321.524.051-37

Or maybe you want to strip your formatted CPF:

String unformattedCpf = Cpf.strip(formattedCpf); // 32152405137

And you can validate a formatted or unformatted CPF:

if (validateCpf(myCpf)) {
  print("CPF is valid");
} else {
  print("CPF isn't valid");
}
