Open suggestions when focus on field

[stefanop1]

Thanks for this great library.
I am not sure if I missed this. It is possible to open the suggestions list when I go into field?

Hello @stefanop1! Yes you definitely can do this:

You just need two extra properties to test:
BoxController and FocusNode. Create and give them to your FieldSuggestion widget.

final boxController = BoxController();
final focusNode = FocusNode();

Then initialize a listener for the focusNode in initState:

 focusNode.addListener(() {
      boxController.show!();
      // Also you can do something else here ...
 });

If you're using the basic FieldSuggestion (I mean without custom builder) it'd open just an empty box the first time.
So, something like that:

So, to avoid this weird behavior, basically, you can use custom builder (that's the best solution). Or do something like that:

Set custom search function to your FieldSuggestion widget:
Which will always keep your box open until you close it.

customSearch: (_, __) => true,

And then convert your focusNode's listener like:

focusNode.addListener(() {
   boxController.show!();
   textController.text = ' ';
 });

The final result would be like that:
