focusIndex property

int get focusIndex

Sometimes it's necessary to know current field index to be able to focus next one, in case a field might lose focus for some time.

e.g. LiteDatePicker uses this

Implementation

int get focusIndex {
  final allFields = liteFormController
      .getAllFieldsOfForm(
        formName: _formName!,
        mountedOnly: true,
      )
      .toList();
  return allFields.indexOf(this);
}
