Developed by Google, Flutter is an open-source and UI application software development kit (SDK) used to develop mobile applications for iOS, Android, Windows, Mac, Linux, etc. Flutter empowers the developers to code smooth and easy cross-platform mobile applications. Various ways that indicate Flutter is setting the trend in mobile app development are:

1. Active code writing and app testing
The Flutter application development process is very efficient. Flutter is a single codebase framework and therefore it eases and accelerates the process, making it easier and more effective. Flutter's single codebase approach helps in cutting down the development time allowing developers to reuse it with diverse plugins. Furthermore, when it comes to testing, a mere quality assurance method is adequate to check the features, program, and functionality of a cross-platform mobile app.

2. Single codebase
The write-once approach feature of the Flutter makes it stand out amongst its likes. It outdoes the traditional barriers of cross-platform approaches where developers had to write various codes for various platforms.
Flutter is considered by most of the developers as Flutter mobile app developers now only have to code once and not individually for both Android and IOS operating systems. Being a hybrid application development framework, Flutter lessens the daily efforts of both – developers and users. Therefore they can promptly update the design, speed, and quality of the application.

3. Best befitted for MVP
Choosing Flutter for application development can aid you in displaying your MVP to the investors. With Flutter, there is no obligation of developing two applications for iOS and Android. Flutter lets you discuss your business model with higher simplicity and aids you in acquiring funding. By skipping the process of testing and developing project prototypes can help you save both resources and time. Flutter honors MVP development. Application development becomes uncomplicated with Flutter as it increases the pace of the development process. Flutter is also compatible with Firebase and hence doesn’t require you to part backends for building easy MVP. Therefore, the Flutter mobile application for businesses will turn out to be a grand success.

4. Utilization of widgets
These days widgets are a very crucial part of the application interface. Applications integrated with Flutter provide a broad range of widgets including fonts, navigation, scrolling, etc that are customizable despite the screen size. Undoubtedly, compared to another cross-platform framework, Flutter mobile apps provide a very fluid UI experience.

5. Hot reloading
Due to its features like “Hot Reloading” or “Hot Restart”, Flutter cross-platform application development is trending amongst the developers. These traits of Flutter allow developers to inspect changes in the code within a second.

Or simply one can say that Flutter allows developers to see the progress side by side while coding. Thus, this increases the productivity of the developers, and also, it is extraordinary for fixing bugs.

6. Simple set up and maintenance
Flutter is comparatively easy to develop and maintain as it is a single codebase framework. As compared to any other app development platform, Flutter enhances the performance of the application and reduces maintenance efforts. Due to the simple and single code used in programming, maintenance of flutter is easy. Modifications are made quickly without the hustle of going back and forth on the codes again and again, once the bug is detected by the team members. Therefore, Flutter comes easy on the pocket as developers do not have to spend additional money on mighty machines.

7. Simple development language
Flutter uses Dart programming language which is based on the in-house language of Google. Dart programming language is a general-purpose and one-source language, and hence developers with even a little knowledge find the language relatively easy and smooth to access than other languages. Dart is not only used for mobile application development framework, but it is also broadly available for developing server, desktops apps, and web.

The single codebase Flutter is not going to stop anytime soon now. Everyone is aware of how swiftly it is advancing towards businesses’ success, keeping in mind the future plots. Flutter has taken over several application development frameworks efficiently and has established itself as an ideal choice for developers and users.
