TOptionTile class

A full-width, touch-friendly selectable row (at least 56dp tall).

Used by the tile mode of TRadioGroup, TCheckboxGroup and TSwitch, and directly for reason pickers and checklists on handheld screens where the small inline radio/check controls are too hard to hit.

TOptionTile(
  label: 'Customer unavailable',
  description: 'Nobody at the address',
  indicator: TOptionIndicator.radio,
  selected: reason == 'unavailable',
  onTap: () => setState(() => reason = 'unavailable'),
)
