Flutter app development boasts a unique feature called hot reload. This allows you to see the changes you make to your code reflected in the app in real time, without the need to recompile and restart the app. This significantly speeds up the development process, letting you iterate and test your ideas quickly.

Imagine you’re working on a new social media app and want to experiment with different button designs or animation effects.

With hot reload, you can make changes to the code, hit a key combination, and see those changes reflected in the running app within milliseconds.

This removes the friction of the traditional development cycle, where you’d have to compile and deploy the app each time to see your changes.

Native-like Performance: 

One of the biggest advantages of Flutter is its ability to create apps with performance that rivals native apps. Flutter uses a custom rendering engine called Skia, which allows for smooth animations, fast scrolling, and a truly native feel on both iOS and Android devices.

Benchmarks consistently show that Flutter apps perform on par with native apps, especially in terms of frame rates and responsiveness.

This is a significant advantage, as users have come to expect a seamless and lag-free experience on their mobile devices. 

A study by iKala compared the performance of a native Android app, a React Native app, and a Flutter app.

The Flutter app development achieved frame rates nearly identical to the native app, demonstrating its ability to deliver a high-quality user experience.

Rich UI and Widgets:

Flutter provides a rich set of customizable widgets that you can use to build visually appealing and interactive user interfaces. These widgets are pre-built UI elements that offer functionalities like buttons, text fields, sliders, and more.
