What is Flutter and How Does it Work?

what is flutter?

Flutter apps are built using the widget approach. Widgets are small, reusable user interface elements that can be combined to form complex interfaces. Widgets in the Material Design library, for example, include buttons, text fields, and sliders, which are common Material Design elements.

Dart is a high-performance, fast-developing typed programming language. You can write a single codebase that compiles to both iOS and Android binaries when developing an app with Flutter. This means you can code your app once and deploy it to both app stores without maintaining two separate codebases.

Flutter includes a set of tools that enable you to test your app on multiple devices simultaneously. This includes emulators or simulators for each platform, as well as physical devices if available.

Flutter is also well-suited to continuous integration (CI) and deployment (CD). This means that you can build and deploy your app to TestFlight or App Store Connect automatically after each code change.
