Get Categories

You can get your store's registered categories as a List<Category>, list of categories with the calling all() on categories like this :

Using await/async :

List<Category> allCategories = await YouCan.instance.categories.all();

Using a FutureBuilder:

FutureBuilder<List<Category>>(
    future: YouCan.instance.categories.all(),
    builder: (context, snapshot) {
      if (snapshot.hasData) {
        return Text(snapshot.data);
      } else if (snapshot.hasError) {
        return Text("Error: ${snapshot.error}");
      } else {
        return CircularProgressIndicator();
      }
    },
  ),
