Widget Life Cycle In Flutter

Image
  Widget Life Cycle In Flutter Flutter has two types of widgets Stateless Widget, and Stateful Widget. Stateless Widget Stateless Widgets are rendered only once when the widget is loaded. We can't rebuild a Stateless widget based on any user events or changes. Stateful Widgets Stateful Widgets can be rebuilt and have their own Widget Lifecycle to create, update and destroy the widgets. In Flutter, widgets have several lifecycle methods that the framework calls during different stages of their lifecycle. Here are the most important ones: createState(): This method is called during the construction stage of a Stateful widget and creates a corresponding state object. initState(): This method is called during the initialization stage of stateful widget and is used to initialize any resources the widget needs. didChangeDependencies(): This method is called during the dependecies resolution stage of a widget, and is used to handle any changes to the widget's dependencies. build():

Sync&Async with flutter

 Sync & Async Flutter Asynchronous (async) and synchronous (sync) programming are fundamental concepts in modern   software development, especially in mobile application development using Flutter.   Synchronous Programming Synchronous programming, often referred to as "sync," is a straightforward approach where tasks are executed sequentially. In this model, each task waits for the previous one to complete before it starts. This can lead to a blocking operation where the application becomes unresponsive if a task takes a long time to complete.   Example:    void main() {   print('Task 1');   print('Task 2');   print('Task 3'); } Output Task 1 Task 2 Task 3 Each task waits for the previous one to complete, ensuring a predictable and ordered execution.   Asynchronous Programming   Asynchronous programming, or "async," allows multiple tasks to run concurrently without waiting for each other to complete. This is partic

Url Launcher using Flutter

  Exploring the URL Launcher Package in Flutter: A Comprehensive Guide Introduction: In the world of Flutter app development, integrating external functionalities like opening URLs, making phone calls, sending emails, and more is essential for creating robust and user-friendly applications. This is where the URL Launcher package comes into play. This package provides a simple and efficient way to interact with external resources and services directly from your Flutter app. What is a URL Launcher? The URL Launcher package is a Flutter plugin that allows developers to launch various types of URLs and perform actions such as opening web pages, making phone calls, sending emails, and launching map applications. It abstracts the platform-specific code required for these tasks, making it easy to incorporate these functionalities into your Flutter apps regardless of the platform (Android or iOS). Installation: To start using the URL Launcher package in your Flutter project, follow these simpl

Web View Flutter

Exploring WebView in Flutter: Enhancing Mobile Apps with Web Content Introduction: In today's digital age, integrating web content seamlessly into mobile applications has become increasingly important for providing rich and dynamic user experiences. One powerful tool for achieving this integration in Flutter is the WebView widget. In this comprehensive guide, we will delve into the world of WebView in Flutter, exploring its capabilities, use cases, and best practices for leveraging web content within mobile apps. Understanding WebView:   WebView is a Flutter widget that allows developers to embed web content, such as web pages, HTML documents, or web applications, directly within their Flutter apps. This widget acts as a container for displaying web content within the app's user interface, providing users with a cohesive and integrated browsing experience without leaving the app. Key Features and Capabilities: Cross-Platform Compatibility: WebView is supported on both Android a

Permission Handler using flutter

  Permission Handler using flutter   The permission handler in Flutter refers to a software package or library that facilitates the management of permissions within a mobile application developed using the Flutter framework. Specifically, it simplifies the process of requesting, checking, and handling permissions required to access device features or sensitive data on both Android and iOS platforms. The permission handler typically provides a unified API that abstracts away platform-specific differences, allowing developers to interact with permissions in a consistent manner across different devices and operating systems. This abstraction streamlines the development process and ensures that permission-related tasks can be implemented efficiently within the Flutter application codebase. Key functionalities of a permission handler include: Requesting Permissions: Enables developers to programmatically request permissions from the user at runtime, typically through a dialog or system pro
