How to call the validator on a button click ? #707

Closed PKReejesh closed 1 week ago

PKReejesh commented 1 week ago

I wish to call the validator on a button click and highlight the error, is that possible with this widget ?

I have seen the autoValidateMode mode, but is there a manual way to trigger the validate method and show the error ?

Yes you can, use AutovalidateMode.disabled and validate your form in demand by calling formKey.validate() Where formKey is GlobalKey to be assigned to your Form .

don't forget to implement validator for your DropdownSearch

Take a look here .

Please don't hesitate to like the repo and the lib if it's helpful for you.
