Flutter和Kotlin之间的区别

Flutter和Kotlin是用于构建移动应用程序的两种领先技术。 Flutter是一个框架,而Kotlin是一种编程语言。框架用于特定问题。在Flutter中,我们可以使用几种内置函数来完成应用程序,而编程语言对应用程序开发没有任何限制。在这里,我们将基于各种参数比较Flutter和Kotlin之间的差异。在进行比较之前,我们将简要讨论这些技术。

什么是flutter ?

是一个跨平台的UI工具包,它使我们能够使用Dart编程语言为移动,Web和桌面创建快速,美观,本地编译的应用程序。它使用一种编程语言和单个代码库构建应用程序。它是免费和开源的。 Google最初于2017年5月开发了它,现在通过ECMA标准进行管理。它是提供卓越的原生体验的一种日益普及的技术。

Google引入了它作为SDK(软件开发工具包)来创建适用于iOS和,iOS上的Objective C和Swift集成在一起。

flutter 的特征

以下是Flutter的基本功能:

开源: Flutter是一个用于构建桌面和移动应用程序的开源框架。

跨平台开发:它允许开发人员编写一次代码,并且可以在不同平台上运行。它节省了开发人员的时间,精力和金钱。

热重加载:如果我们修改了Flutter代码,则可以通过热重加载立即看到更改。由于此功能,开发人员可以立即修复错误。

小部件:小部件用于开发可定制的特定设计。 Flutter有两组小部件:Material Design和Cupertino小部件,可在所有平台上提供无故障的体验。

可访问的本机功能:通过此功能,我们可以轻松访问Flutter的本机代码,第三方集成和用于应用程序开发的平台API。

最少的代码: Flutter将Dart编程与JIT和AOT编译方法结合使用,以改善整体启动时间,功能和应用程序性能。 JIT无需费力即可刷新UI。

什么是科特林?

在JVM上运行的静态类型的语言,可以在使用Java的任何地方使用。我们可以使用它来开发Android应用程序,服务器端应用程序等等。它正在成为采用程度最高的技术。它是由JetBrains开发的,并于2010年通过一个小项目发布。 Kotlin的首次正式发布于2016年2月。它是根据Apache 2.0许可开发的。 Kotlin具有一个名为“ Kotlin Multiplatform ”的特殊功能,可以与JVM字节码,JavaScript或LLVM代码兼容。在Kotlin中开发的应用程序范围是无限的。

Kotlin的功能

以下是Kotlin语言的功能:

简洁: Kotlin语言允许开发人员减少使Kotlin更加简洁的额外代码的编写。

空安全性: Kotlin是空安全性语言。此功能的主要目的是从代码.Interoperable中消除NullPointerException。

互操作性:此功能使开发人员可以轻松调用Java代码,并且Java也可以使用Kotlin代码。

智能强制转换:它显式地转换不可变值,并自动将值插入其安全强制转换。

工具友好:我们可以使用命令行以及任何Java IDE来构建Kotlin程序。

扩展函数: Kotlin支持扩展功能和扩展属性,这些扩展功能和扩展属性有助于扩展类的功能,而无需接触其代码。

下面的比较表解释了Flutter和Kotlin之间的主要区别:

Parameters Flutter Kotlin
Definition It is a cross-platform mobile framework that provides mobile app SDK to the developers and designers to build modern mobile apps for iOS and Android. It is detailed as statically typed programming language for the JVM, Android, and the browser. It is 100% interoperable with Java.
Developed By It is a framework that was first introduced by Google. It is a programing language that was first introduced by JetBrains.
Released 2017 2010
Language Stack It uses Dart programming to build mobile apps. It is itself a programing language that uses Java, JVM, JavaScript, and Native for creating applications.
Popularity Its popularity on GitHub has 88.7k stars and 11.7k folks. Its popularity on GitHub has 31.1k stars and 3.8k folks.
Performance Its performance is amazing because it uses Dart programming, and there is no need to use JavaScript Bridge for starting interactions with the app. Its performance is slow because it uses JavaScript and 100% interoperable in Java that decreases the speed of an application.
Learning Curve In Flutter, developers must have to learn Dart programming to build an app. It has an easy learning curve because it is very similar to Java.
Documentation It has well organized and more informative documentation where we can get everything that we want in one place. It also provides well-structured documentation to the developers. Since it is in the development phase, its libraries can be changed at any time.
Testing Support It has a wide variety of testing features along with a unique widget testing feature. Its main focus is to deliver backend development services and uses Firebase as a secure backend option.
Hot Reload Supported Not Supported
App Size The size of the Flutter app is bigger. The size of the Kotlin app takes less size as compared to Flutter.
Integration of third-party libraries and tools Since Flutter is a UI tool, so it needs third-party libraries and tools to bridge a connection with the native environment. It does not require third-party libraries and tools to bridge a connection with the native environment.
Pricing It is entirely free to utilize Flutter system technologies and their libraries. It is also free, so there is no better choice in this matrix.
Deployment Options It can deploy on Mobile, Desktop, and Web. It can deploy on Mobile, Desktop, and Web.
Popular Apps Hamilton, Google Ads, Alibaba, Cryptograph, etc. Pinterest, Coursera, Evernote, etc.
