Flutter: How to minimize width of DropdownButton
Wrap Dropdown button with ButtonTheme and add alignedDropdown = true like:
ButtonTheme(
alignedDropdown: true,
child: DropdownButton(...),
)
alignedDropdown will match the menu items' width with buttons. Then we need specific width, so wrap ButtonTheme with SizedBox or Container:
SizedBox(
width: 25, // Your width for dropdowns
child: ButtonTheme(...),
)
