New post on /r/flutterdev subreddit: The getter 'documents' isn't defined for the type 'QuerySnapshot<Map<String, dynamic>>' The type 'List<QueryDocumentSnapshot<Map<String, dynamic>>>' used in the 'for' loop must implement 'Iterable' with a type argument that can be assigned to 'Map<dynamic, dynamic>'.dart(for_in_of_invalid_element_type) Changed from this code:

class CategoryServices { String collection = "categories"; Firestore _firestore = Firestore.instance; Future<List<CategoryModel>> getCategories() async => _firestore.collection(collection).getDocuments().then((result) { List<CategoryModel> categories = []; for (DocumentSnapshot category in result.documents) { categories.add(CategoryModel.fromSnapshot(category)); } return categories; }); } 

To this, but getting an error. Where did I go wrong?

class CategoryModel { String? image; String? name; CategoryModel({this.image, this.name}); // receiving data from server factory CategoryModel.fromMap(map) { return CategoryModel(image: map['image'], name: map['name']); } // sending data to our server Map<String, dynamic> toMap() { return { 'image': image, 'name': name, }; } } class CategoryServices { String collection = "category"; FirebaseFirestore _firestore = FirebaseFirestore.instance; Future<List<CategoryModel>> getCategories() async => _firestore.collection(collection).get().then((result) { List<CategoryModel> categories = []; for (Map category in result.docs) { //error at this line categories.add(CategoryModel.fromMap(category)); } return categories; }); }

New post on /r/flutterdev subreddit: Tools and improvements for DX and testing. What do you use? Hi All,I have been recently working on certain tools to help improve my own workflow for flutter and for architecture in general and this got me curious. What do you guys use?The things I am interested in are the followingHow do you ensure good code quality?Are you guys using git hooks or something similar?What does your CI/CD pipeline consist of?Do you guys have any specific testing strategies?What tools do you use for debugging and logging?How do you ensure analytics-related code is not entangled with business logic?How do you manage different environments? (Staging, Production, etc) I think in general it's things like what do you do to ensure a scalable code base that is architecture agnostic?

New post on /r/flutterdev subreddit: Update on My Chat App using MQTT Protocol. Hello,Recently I posted my Repo of a Flutter application that uses MQTT Protocol as chatting protocol.Thank you for your nice words, and special thanks to those who raised issues.Some of you asked why not Firebase like 99% of online tutorials and packages. Those are some of my motivations:Price, Firebase could be really expensive if the app grows in the future.On-premise solution. Messages are sensitive data, and storing them on the cloud could not be a good option for enterprises.MQTT is quite a universal protocol which already used in different fields. Using MQTT spares you from the instability due to multipe updates of Firebase packages...And well... to give another choice to the community is a good thing :)I am thinking to do some cleansing and publish the core features as a package on pub dev. Before doing that I need you to evaluate the work and try it out, any feedback is welcome.This is the repo on GitHub. September 26, 2021 at 12:11PM by Coffee__2__Code https://ift.tt/3o9JOPy
