decorateInput method

@override Widget decorateInput(Widget field)

Extra chrome a style paints around an input (inset shadow, frost, clay drop…). Applied to the single-field otpField and to every digit box of otpBox, so both looks stay identical. Not used for the underline input style, which is chrome-less in every design.

Implementation

@override
Widget decorateInput(Widget field) {
  return _frosted(
    fill: theme.inputBackground,
    radius: inputRadius,
    child: field,
  );
}
