Explain the concept of futures and streams in Dart.

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 […]

What are Flutter channels and why are they used?

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 […]

What is (AOT) and just-in-time (JIT)

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 […]
