Remove line decoration under every form item

[christianarduino]

Is there a fast way to remove this blue line that is automatically added under each item on the form?

Hi @christianarduino.
Yes, you can! In your InputDecoration, set border to InputBorder.none.

You can apply this to the whole form by setting the attribute in your inputDecorationTheme.

Maybe I'm the one who puts something wrong?

FormBuilderSlider(
  attribute: "slider",
  validators: [FormBuilderValidators.min(6)],
  min: 0.0,
  max: 10.0,
  initialValue: 1.0,
  divisions: 20,
  decoration: InputDecoration(
    labelText: "Number of things",
    border: InputBorder.none,
  ),
),

The blue border always remains also for other elements of the form (such as checkboxes).
The widget in the real code is inserted in a FormBuilder obviously

It doesn't seem like it. I'm testing locally and everything seems to be working a-okay - I know classic answer ;-)
Which version of the package are you using?

[christianarduino]

I think the latest: flutter_form_builder: ^3.8.2

Okay, I found the solution. I had set inputDecorationTheme enabledBorder and focusedBorder. This way InputBorder.none doesn't work for individual elements of the form
