initialSelection property

T? initialSelection
final

The value used for an initial selection.

This property sets the initial value of the dropdown menu when the widget is first created. If the value matches one of the dropdownMenuEntries, the corresponding label will be displayed in the text field.

Setting this to null does not clear the text field.

To programmatically clear the text field, use a TextEditingController and call TextEditingController.clear on it.

Defaults to null.
