Flutter: State Management-2

   The BLoC pattern — ViewModel + Reactiveness ️⚡️ We can use pure dart class as ViewModel and keep the properties as reactive streams. The view layer can add an action in the ViewModel using StreamController’s Sink or Subject from the RxDart package. Those actions can be processed and converted to the View representable property streams in the ViewModel. From the View layer, widgets can react to the ViewModel streams using the StreamBuilder widget. This is the purest reactive form of state management where we can rebuild the necessary widgets by using specific property stream in the StreamBuilder. Following this pattern has additional challenges though. As there will be multiple Sinks for accepting different actions and multiple streams exposed for UI reactivity, it’s very easy to lost tracking the data flow. Let’s see what our rising community has done to solve this problem 😄. 4. The BLoC package The BLoC package mixes the ideology of the BLoC pattern &...

  Introduction to Flutter Installation In this section, let us see how to install Flutter SDK and its requirement in a windows system. Step 1 − Go to URL, https://flutter.dev/docs/get-started/install/windows and download the latest Flutter SDK. As of April 2019, the version is 1.2.1 and the file is flutter_windows_v1.2.1-stable.zip. Step 2 − Unzip the zip archive in a folder, say C:\flutter\ Step 3 − Update the system path to include flutter bin directory. Step 4 − Flutter provides a tool, flutter doctor to check that all the requirement of flutter development is met. flutter doctor Step 5 − Running the above command will analyze the system and show its report as shown below − Doctor summary (to see all details, run flutter doctor -v): [√] Flutter (Channel stable, v1.2.1, on Microsoft Windows [Version 10.0.17134.706], locale en-US) [√] Android tool chain - develop for Android devices (Android SDK version 28.0.3) [√] Android Studio (version 3.2) [√] VS Code, 64-bit ed...

Dart: mixins

  Mixins in Dart The mixin keyword was introduced in dart 2.1 and it is analogous to abstract class in some ways and different from it in other way. Like abstract class , you can declare abstract methods in mixins and it cannot be instantiated. But unlike abstract , you can’t extend a mixin. You can either use the keyword mixin , abstract class or a normal class as a mixin. Let’s take a look at how we can solve the above problem with mixins. Always keep in mind that mixin is not multiple inheritance instead they are just a way to reuse our code from a class in multiple hierarchies without needing to extend them. Its like being able to use other people assets without being their children When mixing classes, the classes used as mixins are not parallel but instead on top of the class using it. This is the reason why methods do not conflict with one another, allowing us to use codes from multiple classes without having to deal with the vulnerabilities of multiple inheritan...
