Trying to get validator to work. about prompt_dialog HOT 9 CLOSED

It appears that the validate function is never called.

TextButton(
  onPressed: () => Navigator.pop(context, value),
    child: (textOK != null) ? textOK : const Text('OK'),
),

should be something like this

TextButton(
  onPressed: () {
    if (_formKey.currentState!.validate()) {
      Navigator.pop(context, value);
    },
  child: (textOK != null) ? textOK : const Text('OK'),
),

See https://docs.flutter.dev/cookbook/forms/validation

from prompt_dialog.

Update I put a breakpoint and a print statement in the validate itself and neither gets hit so I suspect it's never invoked. Also at this point, I'm only debugging on web, not mobile.

Thanks for the nice clean widget.

+1, this widget is really good!

I can confirm the issue also happens on mobile (android)

@dakamojo Awesome!!

Could you make a pull request?

@gtgalone I'm making an attempt. But I'm unsure about how to get the key for the form to call validate. In the current implementation the key is based on keyCtr which is incremented every time the ShowPasswordIcon is pressed. Is there a reason the key needs to change? Or can the key be a GlobalKey that doesn't change?

from prompt_dialog.

I am working on this. It seems that the key has to be created from a Stateful Widget, a Stateful Builder doesn't work. I'm refactoring to use a private Stateful Widget but keeping the same functional signature.
