GlobalKey is a special key in Flutter that provides a way to uniquely identify a widget across the entire application. It allows you to reference and interact with a specific widget from anywhere in your code. Here’s how GlobalKey works: In summary, GlobalKey is a powerful tool in Flutter that allows you to uniquely identify and interact with widgets across […]
Flutter channels, often referred to as platform channels, are a crucial mechanism for enabling communication between Dart code (used in Flutter) and native code (used in Android and iOS). They allow Flutter apps to access platform-specific APIs and perform tasks that are not directly supported by Flutter itself. Here’s a detailed explanation: Purpose of Flutter […]
Flutter uses a combination of platform channels and plugins to handle platform-specific code for Android and iOS. Here’s how it works: In summary, Flutter handles platform-specific code by providing a flexible and robust mechanism for communication between Dart code and native code using platform channels. This allows developers to access platform-specific APIs and perform tasks […]
In Flutter, “AOT” and “JIT” are two different compilation modes that the Flutter framework uses to execute Dart code on different platforms. These modes have distinct characteristics and purposes: In summary, AOT (Ahead-of-Time) compilation is used for producing optimized, platform-specific release builds with better performance and faster start-up times. JIT (Just-in-Time) compilation is used during […]
In Flutter, keys are used to control the identity of widgets in the widget tree, especially when the widget tree changes or gets rebuilt. They play a crucial role in preserving the state of widgets, managing reorderable lists, and improving the efficiency of the frameworkâs diffing algorithm. Why Do We Need Keys in Flutter? When […]
BuildContext is an important concept in Flutter that represents the location of a widget in the widget tree. It provides information about the current context in which a widget is being built. Here are some key points about BuildContext: Location in the Widget Tree: Each widget in Flutter is associated with a BuildContext that identifies […]
The pubspec.yaml file is a critical file in a Flutter project. It serves several important purposes: Dependency Management: The pubspec.yaml file is used to manage the dependencies of a Flutter project. It lists all the external libraries and packages that the project relies on. These dependencies can include UI libraries, state management solutions, networking packages, […]
In Flutter, the “widget tree” refers to the hierarchical structure of widgets that are used to construct the user interface of an application. Widgets are the building blocks of a Flutter application, representing everything from simple UI elements like buttons and text to more complex layouts and interactive components. Here’s an explanation of the widget […]
Using Flutter for mobile app development offers several key advantages: Single Codebase, Multiple Platforms: Flutter allows you to write code once and deploy it on both Android and iOS platforms. This significantly reduces development time and costs compared to building separate apps for each platform. Hot Reload for Fast Development: Flutter’s hot reload feature allows […]
Dart is a programming language developed by Google. It’s designed for building modern, high-performance applications for a variety of platforms, including mobile, web, and server-side development. Dart is known for its performance, productivity features, and its strong support for object-oriented programming. Here’s why Dart is used with Flutter: Performance: Dart is optimized for fast execution. […]
