Opa, boa tarde,

por exemplo ..eu tenho o JSON.

resultado do JSON

      Geo(

      pessoaJson['phone'],
      pessoaJson['website'],

  Pessoa(

class Enderaco {
  final String street;
  final String suite;
  final String city;
  final String zipcode;

  Enderaco(
    this.street,
    this.suite,
    this.city,
    this.zipcode,
  );
}




class Geo {
  final String lat;
  final String lng;

  Geo(
    this.lat,
    this.lng,
  );
}

O problema todo eh que eu nao consigo puxar os dados quando o JSON esta encadeado. por exemplo eu consigo acessar normalmente os dados de street que esta dentro de address, porem nao consigo acessar geo que esta dentro de address.
