  data1 ~/= data2; // el resultado es asignado a data1
  print('data1 ->: $data1');
}

• Operador bit

 var data1 = 132;
 var data2 = 5;

//multiplicacion
data2 = data1 << 2;  //132*2*2 = 528

//division
data2 = data1 << 2;  //132/2/2 = 33

• parse

var value = int.parse("10000100", radix: 2); //convertir binario a entero

POO

• Class

class vehiculo{

  late String color;
  late String modelo;
  late String marca;
}

• Ejemplo POO

class vehiculo{

  //Variables tardías
  late String color;
  late String modelo;
  late String marca;

  void Arrancar(){
    print("Arrancando Programacion orientada a objetos");
  }
  // primera funcion
  void CambiarValor(int numero){
    for(int i = 0; i<numero; i++){
      print("numero: $i");
    }
  }
  //segunda funcion
  void CambiarMarca(String marca){
    marca = marca;
    print(marca);
  }
}


void main(){
  var auto = new vehiculo();
  int numero = 10;

  auto.color = "Azul";
  auto.marca = "Toyota";
  auto.Arrancar();
  auto.CambiarValor(numero);
  auto.CambiarMarca("Ford");
}

• POO - Herencia

• Sobreescritura de metodos

 @override

• POO clases Abtractas

• Example

// INTERFASES
abstract class EsTransporte{
  void QueTranporteSoy();
}
