Isolates and Java threads share similarities, but they are not equal. Here’s a comparison: Similarities: Concurrency: Both isolates and threads enable concurrent execution of code. Separate execution: Both run independently, without blocking each other. Communication: Both allow communication between concurrent units (via messaging or shared state). Differences: Memory model: Isolates have separate heaps, while threads […]
What is a const Widget in Flutter? In Flutter, the const keyword is used to create constant widgets, which are widgets that do not change during the app’s runtime. A const widget is a compile-time constant, meaning its properties are fixed when the app is compiled, and it does not need to be recreated or […]
What is NKD? The NDK, or Native Development Kit, is a set of tools provided by Android for developers to write and implement performance-critical parts of their applications using native code languages like C and C++. This is particularly useful for tasks that require high performance, such as graphics-intensive applications, games, or algorithms that benefit […]
In Dart, futures and streams are fundamental concepts used for asynchronous programming. They provide a way to handle operations that may not immediately return a result, such as network requests, file I/O, or computations that take time to complete. Futures: Definition: A future represents a potential value or error that will be available at some […]
Isolates in Flutter In Flutter, isolates are a feature of the Dart language, which Flutter is built on. Isolates allow for concurrent execution of Dart code, enabling tasks to run in parallel without blocking the main UI thread. How many Isolates Flutter have in default In Flutter, by default, there is a single UI isolate […]
Learning artificial intelligence (AI) involves understanding various concepts, algorithms, and tools that enable machines to perform tasks that typically require human intelligence. Here’s a roadmap to help you get started and progress in your AI learning journey: Roadmap to Learning AI: 1. Prerequisites: Basic Programming Skills: Start with a programming language like Python, which is […]
Understanding the widget lifecycle in Flutter is crucial for managing the state of your widgets effectively, especially when dealing with stateful widgets. Flutter provides several lifecycle methods that allow you to respond to changes in your widget’s state, from creation to destruction. Here’s a comprehensive example illustrating the lifecycle of a stateful widget with explanations […]
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 […]
