Input Formatting in Flutter's Drop Down Menu text field

I want to use DropDownMenu's text field with Input Formatter but I couldn't find any option. Is there a way to capitalise first alphabets of all words in DropDownMenu's field while user is entering info using keyboard (web or mobile)?

Where DropDownMenu is not required, I have used inputFormatters property of TextFormField. But for this case filterable/searchable DropDownMenu is required.

Other methods using Stack to build my own searchable DropDownMenu does not work when I want to select a menu item by tapping.

Thanks.

Solution

  • DropdownMenu widget now supports inputFormatters property like TextFormField in flutter channle beta. It should be flowing down to stable channel soon.

    Example:

    DropdownMenu(
  dropdownMenuEntries: /*....*/ ,
  inputFormatters: []
)
