[yj-abe]

Steps to reproduce

1. Write a program like the following.

      Column(
        children: [
          TextFormField(
            textInputAction: TextInputAction.next,
          ),
          TypeAheadField<String>(
            direction: VerticalDirection.up,
            itemBuilder: (context, value) {
              return Text(value);
            },
            onSelected: (value) {},
            suggestionsCallback: (search) {
              return ['test'];
            },
          ),
        ],
      ),

2. Enter text in the first TextFormField and click the next button on the keyboard.

Expected results

Focus moves to next TypeAheadField.

Actual results

TypeAheadField is not focused. If I set direction of TypeAheadField to VerticalDirection.down, it works fine.
