String query

The current query string shown in the AppBar.

The user manipulates this string via the keyboard.

If the user taps on a suggestion provided by buildSuggestions this string should be updated to that suggestion via the setter.


String get query => _queryTextController.text;
void query=(String value)


set query(String value) {
  assert(query != null);
  _queryTextController.text = value;
