DgisSearchWidget class

Виджет, представляющий собой поисковую строку и лист выдачи объектов или подсказок.

Пример кастомного билдера для результатов:

DgisSearchWidget(
  searchManager: searchManager,
  resultBuilder: (context, objects) {
    return SliverList(
      delegate: SliverChildBuilderDelegate(
        (context, index) {
          final item = objects[index];

          return item.fold(
            // Handle DirectoryObject
            (directoryObject) {
              return ListTile(
                title: Text(directoryObject.title),
                subtitle: Text(directoryObject.subtitle),
                onTap: () {
                  // Handle directory object selection
                  print('Selected: ${directoryObject.title}');
                },
              );
            },
            // Handle Suggest
            (suggest) {
              return ListTile(
                title: Text(suggest.title.text),
                subtitle: Text(suggest.subtitle.text),
                onTap: () {
                  if (suggest.handler.isObjectHandler) {
                    final item = suggest.handler.asObjectHandler!.item;
                    print('Selected object: ${item.title}');
                  } else if (suggest.handler.isIncompleteTextHandler) {
                    final queryText = suggest.handler.asIncompleteTextHandler!.queryText;
                    print('Complete search with: $queryText');
                  } else if (suggest.handler.isPerformSearchHandler) {
                    final searchQuery = suggest.handler.asPerformSearchHandler!.searchQuery;
                    print('Perform search query');
                  }
                },
              );
            },
          );
        },
        childCount: objects.length,
      ),
    );
  },
)

Важно при создании своего билдера:

  1. Билдер должен возвращать Sliver-виджет (SliverList, SliverGrid, etc.)
  2. Используйте fold чтобы обработать все возможные объекты DirectoryObject и Suggest
