DropdownButton value: Instance of 'object'

[rodgav]

1. declare DropdownButtonFormField<object?> with List......
2. Run iOS or Android. open formView. ¡work...!
3. back homeView and enter formView. ¡error...!
   I'm call drains and close all streams un dispose().



the problem seems to be when the formView is re-entered. and dropdownbutton doesn't recognize that it should accept a null, as declared.

Can you provide flutter doctor -v and a complete minimal reproducible code sample along with steps to replicate that triggers this issue ?

Also, as a note, please don't post code and error in screenshots as we can't use them. Always post the details in properly formatted text.

Thanks.

@rodgav ¿Puede proporcionar flutter doctor -vuna muestra de código reproducible mínima completa junto con los pasos para replicar que desencadena este problema?

Además, como nota, no publique el código ni el error en las capturas de pantalla, ya que no podemos usarlos. Publique siempre los detalles en texto con el formato adecuado.

Gracias.
