Top 5 advantages of Using Flutter for mobile app owners


Here’s a list of the top five advantages of using Flutter from an app owner’s perspective.
Let’s have a look.

  • Single Codebase: With Flutter, your developers can write a single codebase for your two business apps outlining iOS as well as Android platforms. Having its own set of designs and widgets makes it platform-independent. What’s more interesting is that you can have the same app on two different platforms and easily differentiate those apps.
  • Fewer Checks: Having the same apps on two different platforms means fewer checks and testing issues. You can have a faster QA process. For QA experts, testing becomes easier as only one app is to be tested and analyzed. No doubt if your apps carry some unique change then the quality checks are to be made for both platforms accordingly.
  • Speedy Code Writing: Flutter helps your developers in creating a faster and dynamic mobile application development environment. It’s Hot Reload facility helps in rapid experimentation, debugging, and efficient addition of features in just a few seconds. It helps in attaining a collaborative relationship between developer and designer.
  • Rapid App Development: While scrolling, your business apps won’t show any kinds of cutting or hanging when built with Flutter. Developers get enough room for choosing from an array of widgets with their successful implementation. These ready-to-use widgets help in developing mobile applications rapidly.
  • Minimalistic Designs: Flutter helps in creating new widgets in an easy manner. Combining these widgets with the existing ones and even customizing them is another significance of this technology. This helps in bringing the best of the designs to the table alongside offering user-friendly experiences.

Does Flutter have any cons?

As a mobile app owner, you should have recognized all the benefits that Flutter offers with the above. However, there are a few areas that still need tweaks and modifications.

  • Third-party Libraries – Being a new technology, Flutter lacks enough third-party assistance. The currently available third-party libraries are limited which proves to be a downside.
  • File Size – Though current mobile devices have large storage capacities; it cannot be neglected that the size of native mobile apps developed with Flutter (in MB) is much larger than native Java (in KB).
  • Skill Requirement – Flutter is definitely easy to use and can even be learned by non-developers. However, to learn this technology you have to learn and understand the Dart programming language.

Reading all that’s being said till now, if you still think Flutter as your go-to solution to build business mobile apps, let’s go through some points when it should not be your choice:

· Building applications with rare native libraries
· Creating AR/VR apps
· Developing small-sized spontaneous web and mobile apps
