Flutter provider vs rxdart12/27/2023 There is also the option it on the device's browser, ability to share a story, or have it added to the user's list of favourites. Tapping on a story will be default, open it "in-app". Settings page - for toggling on and off dark mode and how stories should be opened.Favourites page - for keep track of favourite stories.Top stories page - for displaying top stories.New stories page - for displaying new stories.Overview and architectureīreaking down the app, it essentially consists of four pages This is a basic application that connects to the Hacker News API to display stories and is hosted on GitHub here. To illustrate, lets dissect an application I've written called SUpNews. Reactions - responsible for reacting to changes in state.Actions - responsible for mutating state.Observables - represents part of your application's state.It makes use of three core concepts as described here Code generation can also make it easier for developers to work by reducing the amount of code developers need to write to wire everything up. MobX provides similar capabilities that doesn't require dealing with streams. Some developers may consider working with streams a complex topic and that setting up the BLoC pattern involves too much effort although there are packages that can help get around that. app has progressed from loading data to finish loading) and the StreamBuilder widget will rebuild the UI in response. ![]() The stream, which may be implemented using RxDart, will contain information on if the state has changed (e.g. To summarise though, it requires using the StreamBuilder widget that is wired up to listen to a stream (which that may reside in, say, a view model. There are quite a few resources that have gone through the BLoC pattern so I won't dwelve into it much detail. Whilst researching for ways that could help manage updating the UI within Flutter apps that were similar how I would normally do so in the past, two approaches that stood out to me were the BLoC pattern and MobX. The UI would written in XAML and with the ability to wire up the UI with a view model through data binding. NET applications, MVVM has become the standard architectural pattern. Having come from a background where I've worked on building mobile and desktop. When looking at building applications for Flutter, state management has become a hot topic that there's now a dedicated section on it on the official Flutter website. I have updated the code to use the latest version of provider etc Besides that, the rest of the article should still be of use to developers looking to use MobX. This includes a change to how I now recommend structuring applications whereby dependencies are passed directly to via constructor. Readers should also check as I've contributed to the official documentation on how to use ProxyProvider. I may look at updating the app to make use of it at a later stage. ![]() Import './widgets/profile_picture_widget.Note: at the time of writing this article, the ProxyProvider class wasn't available in the provider package. The next step is to create the registration page view and layout the widgets: import 'package:flutter/material.dart' The goal is to replicate this design and build a fully functional registration experience. I imported all the packages I need in pubspec.yaml. Here is the current MeetUp app registration design: MeetUp Registration Page Design The exercise was designed to be a learning experience so you may have a better way to build such an app. To get familiar with Flutter, I decided to build a registration application. I copied the registration page design from the MeetUp app and built a clone in Flutter. Below is the process I used to build the app. The possibility to build Flutter apps and extend them to work on the Web with project Hummingbird, as well as native applications for desktop operating systems like Windows, Linux and Mac OS with Flutter Desktop Embedding.Robust widget libraries for iOS and Material Design.Good IDE support with Android Studio (my preferred IDE for Flutter development).Flutter seemed to solve many of the rough edges I faced when working with other mobile technologies: XAML. I started going down that path too until I saw Flutter. Many enterprise developers will feel right at home working in Xamarin because of C# and Mobile apps are fun to build. I’ve explored building apps for iOS using Objective-C and Swift and I’ve also built apps using Java for Android. While both platforms and technologies have advantages and disadvantages, it’s frustrating building the same application twice for both platforms, especially if you’re a single developer. When Microsoft acquired Xamarin I immediately saw a tremendous improvement in opportunities and tooling around Xamarin.
