What is Flutter?

Flutter is a Google-created free and open-source mobile UI framework that was introduced in May 2017. In a nutshell, it enables you to develop a native mobile app using only one codebase. This implies you can design two different apps using the same programming language and codebase (for iOS and Android).

You'll utilise the Dart programming language to create Flutter apps. Google established the language in October 2011, but it has come a long way in the last several years.

Dart is a front-end programming language that may be used to create mobile and online applications.

Dart is a typed object programming language that you may learn if you have some programming experience. Dart's syntax is comparable to JavaScript.

Why use Flutter?

Developers aren't limited to a single cross-platform mobile framework when it comes to creating apps. In fact, while the majority of developers (42 percent) prefer React Native, Flutter usage in 2020 (39 percent) has increased significantly from Flutter usage in 2019. (30 percent ).

Some features of Flutter:

• Hot-Reload: Flutter's hot reloading helps developers save time by allowing them to view the changes they've made in real time. This feature allows developers to be much more efficient and productive. Hot reload in Flutter is superior to similar capabilities in competitors. It enables the developer to pause code execution, make changes, and resume the code from the same location. This significantly accelerates development and allows for greater experimentation.
• Minimal code and access to native features: Flutter allows developers to use Dart, which is compiled straight into the ARM code of mobile devices and helps applications not only run faster but also launch faster.
• UI customization potential: A huge advantage of Flutter is the ability to customize everything you see on screen, regardless of the complexity of the element. The amount of effort required is fundamentally lower than that required on native platforms’ development software.

Simple Application - Quiz App
