Flutter : Update text using Valuenotifier

I am using valuenotifier to update a text as an alternative to having a stateful widget and calling setstate. I was able to get the selected value from the dropdownFormFieldbut could not display it.

Simply add this to the onChanged method:

_text.value = value.toString();

This will update the value of your ValueNotifier and the ValueListenableBuilder will catch it and rebuild.
