what is flutter? Everything you need to know about it

What is Flutter?

Flutter is Google’s mobile app SDK for crafting high-quality native interfaces on Android and iOS in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.  Flutter works with existing code,  makes reactive UIs easy, runs on Android & iOS, and is extensible. In addition to being a full-fledged mobile development framework, Flutter also offers widgets and tools that allow you to create animations using Skottie, a FAB (floating action button) library called FlatButton, a TextField for capturing user input called FloatingLabelField, and more.

Flutter is a mobile UI framework that allows developers to build beautiful native applications for both Android and iOS from a single codebase.

In a nutshell, Flutter is Google’s mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. You can develop an app with both native platform look-and-feel as well as original branding. Flutter embraces reactive programming, which means your UI will always be up to date with the latest data.

  • Conclusion.
  • Closing Remark.
  • Code Migration Plugin can only transform the UI. Code customization is strictly limited to change the widgets and components inside of a flutter app. The purpose of this plugin is to make it easier to switch between native and flutter apps.
  • Putting code changes into separate plugins can be a very tedious process and it is hard to ensure that all the code is maintained regularly. We have seen how this freedom has given birth.
