Reactive programming is a programming paradigm that allows for event-driven, asynchronous programming by using reactive streams. Flutter provides support for reactive programming through the use of streams and the StreamBuilder widget.
In Flutter, a stream is a sequence of asynchronous events that can be listened to and responded to. StreamBuilder is a widget that listens to a stream and rebuilds its child widget tree whenever a new event is emitted by the stream. This allows for reactive updates to the UI in response to changes in the data or state of the app.
Dart, the programming language used by Flutter, provides a native implementation of reactive programming through the use of streams and the Stream API. This allows developers to easily create and manipulate streams of data within their Flutter apps.
Reactive programming can be particularly useful in Flutter apps that need to handle large amounts of data or complex user interactions, as it allows for efficient and responsive updates to the UI in real time. However, it does require a good understanding of asynchronous programming and reactive streams, which can be challenging for some developers who are new to these concepts.
How Flutter works
Flutter operates differently than other cross-platform frameworks, as it directly requests the platform for the canvas needed to draw the UI and access device resources such as Bluetooth, audio, or touchscreen, as seen in the figure below. Unlike other frameworks, Flutter doesn't require a bridge to convert widgets into native components, which can impact performance. Instead, Flutter takes on the responsibility of drawing pixels directly on the screen, resulting in a fast and highly responsive app.
Flutter's approach to UI rendering can be compared to a lightweight 2D game engine, where the framework handles all aspects of drawing and updating the UI elements efficiently. This design choice enables Flutter apps to deliver a superior user experience across different devices and operating systems. By minimizing the reliance on external components, Flutter ensures that the app's performance remains consistent, no matter the platform it is running on. Overall, Flutter's unique approach to cross-platform development makes it an ideal choice for building fast, efficient, and visually stunning mobile apps.
