Flutter: State Management-2

-
Image
   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 &...

Thread Synchronization In Java

-
Synchronization in java is the capability to control the access of multiple threads to any shared resource.Java Synchronization is better option where we want to allow only one thread to access the shared resource.The synchronization is mainly used to To prevent thread interference. To prevent consistency problem. Types of Synchronization There are two types of synchronization: Process Synchronization Thread Synchronization Here, we will discuss only thread synchronization. Thread Synchronization: There are two types of thread synchronization mutual exclusive and inter-thread communication. Java synchronized method: If you declare any method as synchronized, it is known as synchronized method. Synchronized method is used to lock an object for any shared resource. When a thread invokes a synchronized method, it automatically acquires the lock for that object and releases it when the thread completes its task.

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...
