Introduction
Flutter is Google’s open source toolkit for helping developers build iOS and Android apps moreover it is one of the primary methods of developing applications for Google Fuchsia.Flutter uses C, C++, Dart, and Skia (a 2D rendering engine) as its backbone.
The Flutter framework makes it easy for you to build user interfaces that react smoothly in your app while reducing the amount of code required to synchronize and update your app's view.
Flutter makes it easy to get started building beautiful apps, You will get material Design in case of Android and Cupertino widgets in case of iOS.In simple, flutter provides a native experience to Users.For developers, Flutter lowers the bar to entry for building mobile apps. It speeds up development of mobile apps and reduces the cost and complexity of app production across iOS and Android.For designers, Flutter helps deliver the original design vision, without loss of fidelity or compromises. It also acts as a productive prototyping tool.
The initial question that arises as we here about a technology that supports multiple platforms is about its performance .flutter provides an excellent performance.Developers can easily achieve a constant 60fps. Flutter apps run via natively compiled code – no interpreters are involved. This means Flutter apps start quickly. Now about native API access.flutter gives access to some platform-specific services and APIs from the operating system.
Coding
How we are going to code?Do we have to use JAVA ?or KOTLIN? Or something else?
You'll write your Flutter apps in Dart.Dart is a general-purpose programing language developed by Google and its syntax is similar to Java, JavaScript, C#, or Swift. Dart is compiled using the standard Android and iOS toolchains for the specific mobile platform where your app needs to run.
