I have a simple TextFormField in my app, how can I make that when I press the first letter, there should be dropping down a list with every option that begins with that specific letter? And when I pressed the second letter, only the valid options remain, and so on and so on. What is the best way to do this?

Try using the flutter_typeahead package.

I think you could try dropdown_search https://pub.dev/packages/dropdown_search, this package seems helpful

instead of textformfield try to use the autocomplete widget
