Developers have it as one of their main options. Although it has some problems, it can help you build multiple platforms using the same software.

With Flutter's SDK, you can create applications for both iOS and Android in no time at all.

Additionally, it is a crucial tool for developing Fuschia apps for Google. Apps built with the Flutter framework are cohesive and dynamic, and they operate well on every platform. Using the Flutter technology, developers have built some very remarkable apps.


  • Developing a minimum viable product (MVP) is a breeze using Flutter. You may save time and effort by developing a single Flutter app that works just as well as native iOS and Android apps.
  • Flutter offers a complete collection of widgets inspired by Google's Material Design.
  • There are a lot of pre-built options for native iOS and Android applications that allow programmers to use Continuous Integration (CI) systems such as Jenkins.


  • The Flutter framework is not compatible with TV systems like Apple's or Android's. 
  • Despite being created by Google, a number of libraries already contain features that are ready to be implemented. When contrasted with native development, Flutter is still lacking.
  • The app's size tends to be larger when Flutter is used because it utilizes integrated widgets instead of platform widgets.


Ionic is a free application development framework for building cross-platform apps with a large collection of pre-made components that utilize web technologies such as HTML5 and JavaScript. It enables you to create apps with a single codebase that can run on several platforms. Creating powerful apps with many customization options, this tool works well with AngularJS. Similar to some frameworks on this list, code reusability is a massive advantage of Ionic, allowing developers to create mobile apps while saving a lot of time.


  • Ionic's development speed is much quicker than other frameworks. Its Angular foundation allows developers to see their work in progress on a web browser.
  • It is really easy to get going since there are pre-made application templates and settings already included.
  • You can reuse a huge chunk of code for other similar projects as well.
  • There are a number of UI components to choose from.


  • Programmers claim that testing an app is not always easy. Because of technical limitations, it is not possible to test the on-device features using a web browser;
  • Older Android phones and tablets will have a hard time operating Ionic applications since they utilize the default browser of the device. Smartphones running Android 4.0–4.3 will automatically launch the Android browser instead of Chrome;
  • Ionic is not going to be able to handle the project's complicated visuals.


When it comes to building programs that can run on several platforms, Node.js is unmatched. This cross-platform mobile development framework is based on the Chrome V8 JavaScript engine and is used to execute JavaScript programs. This open-source framework allows programmers to create flexible networking programs that run on the server side. The efficiency and responsiveness of Node.js cross-platform programs are intrinsic qualities of the language. The framework can manage several connections at once. Plus, it has a ton of useful JavaScript modules for creating web apps.


  • You can see some code on both the client and server sides, but not too much. An important point to keep in mind is that objects in the browser and the backend might have identical names but have totally distinct capabilities.
  • You have access to a passionate community. Web developers may create and distribute their own modules and packages thanks to the open code. In many cases, the components work well together.
  • Although there will be many recognizable instruments, there will also be new ones that you'll need to learn. The result is something that is easy to understand and use.
  • New features and upgrades are added all the time. Npm makes it easier for developers to access an ever-expanding collection of pre-built modules and third-party libraries.


  • Dealing with computationally intensive jobs degrades performance. With too many tasks pending, the app becomes complicated and it's hard to figure out the code.
