Cannot add validation to the depend-on field

[bocanhcam]

I have this simple code that requires users to fill in the billing_name if is_billing is true.
However, the validation is not working at all. I still can submit the form without filling in the billing_name when is_billing is checked.
show() still works.

public function fields(NovaRequest $request)
    {
        return [
            Boolean::make('他に請求先を指定','is_billing')->onlyOnForms(),
            Text::make('請求先氏名','billing_name')
                ->hide()
                ->dependsOn(['is_billing'], function (Text $field, NovaRequest $request, FormData $formData) {
                    if ($formData->is_billing === true) {
                        $field->show()->rules(['required', 'max:50']);
                    }
                })
                ->placeholder('（半角50文字まで）')
                ->onlyOnForms(),
        ];
    }

Same in my app, rules set on field in dependsOn closure are not respected.

Bug occurs when other fields is depend on Boolean field (Select works correctly, I didn't check all fields).

Does $formData->bool('is_billing') === true worked for your use case?

@crynobone This worked. I'll close this issue.

$formData->boolean('is_billing') === true
