Bugfix - blinking loadingBuilder

[comerc]

I have blinking loadingBuilder when change focus. Solution - flag isLoading:

      suggestionsCallback: (String pattern) async {
        _isLoading = true;
        try {
          final data = await _load(pattern);
          return data;
        } finally {
          _isLoading = false;
        }
      },
      loadingBuilder: (BuildContext context) {
        if (!_isLoading) return null; // !!!
        return Align(
          alignment: Alignment.center,
          child: Padding(
            padding: const EdgeInsets.symmetric(vertical: 8.0),
            child: CircularProgressIndicator(),
          ),
        );
      },

I'm still seeing this error where LoadingBuilder is called before onSuggestionSelected during initial focus.
