Question

值得注意的是，我的应用程序可以按预期运行，但似乎会不断重建，而不是在进行更改时重建。如果删除getAllFavoriteRecipes函数，则除非来回导航，否则该应用程序将不会更新。即刷新状态。

body: StreamBuilder(
          stream:
              Firestore.instance.collection('users').document(uid).snapshots(),
          builder: (context, snapshot) {
            if (!snapshot.hasData) {
              return Loading();
            } else {
              favoriteIDs = snapshot.data['favorites'];
              getAllFavoriteRecipes(recipeNotifier, favoriteIDs);

获取所有收藏的食谱。

getAllFavoriteRecipes(RecipeNotifier recipeNotifier, favoriteIDs) async {
  //print('Service FavoriteIDs: $favoriteIDs');

  QuerySnapshot snapshot = await Firestore.instance
      .collection('recipes')
      .where('recipeID', whereIn: favoriteIDs)
      .getDocuments();
  List<RecipeList> _recipes = [];
  snapshot.documents.forEach((document) {
    RecipeList recipe = RecipeList.fromMap(document.data);
    _recipes.add(recipe);
  });
  recipeNotifier.recipeList = _recipes;
}

这是一条日志，显示在添加/删除项目时正确重建了该应用程序，但是该应用程序也在不断重建。
