Here is a basic example of how to use the package:

import 'package:cep_finder/cep_finder.dart';

void main() async {
  final finder = CepFinder();

  try {
    final info = await finder.find("01001000");
    print("Address: ${info.logradouro}, ${info.localidade} - ${info.uf}");
    print("DDD: ${info.ddd}");
  } on CepNotFoundException {
    print("CEP not found.");
  } catch (e) {

Error Handling

The package includes custom exceptions to make error handling easier in your code:

• InvalidFormatException: Thrown when the CEP format is invalid or malformed.
• CepFinderException: Thrown for generic errors (connection failure, API error, etc.).
