Hello, I heard about something called Flutter when looking into a new mobile app project. Is it for mobile apps, by any chance? How does it work, and what are its pros and cons? Could I get a general idea from you?
What is Flutter and how is it used?

Flutter is a UI framework developed by Google that can be used across a wide range of platforms, from mobile apps (iOS/Android) to web and even desktop applications. Its biggest advantage is that it allows you to create apps that run on all these platforms from a single codebase.
When compared to traditional native development (Swift/Kotlin/Java) or hybrid frameworks like React Native, it has some key differences. While it may lag slightly behind native development in terms of performance—especially in complex animations—it outperforms React Native, which relies on a JavaScript bridge. Flutter apps run directly on the device’s GPU. The downside, however, is that Flutter apps tend to have larger file sizes (typically an increase of 4-5MB), which can be an issue for apps that need to stay under 10MB.
On the plus side, its widget-based architecture makes UI development incredibly fast. For example, implementing Material Design or Cupertino styles can be done with a single line of code, whereas native development requires designing separate screens for each platform. Additionally, the "hot reload" feature makes the development process extremely efficient—you can see changes instantly without restarting the app after modifying the code.
