Such features can offer extra functionality and great-to-have during the development stage.
  • Easy Testing. Yet another reason to choose Ionic is that mobile app testing is far easier with the framework. It is simple to test it on a desktop browser or perform simulator testing for iOS and Android apps using Cordova commands.

The bottom line, choose Ionic when developing hybrid mobile and web apps with great native power and control, with first-class support for PWAs.

When to Choose Flutter for App Development?

Flutter app development

Now, let’s look at when you may choose Flutter for app development. Here are some compelling reasons:

  • Stability. Flutter’s code is compiled into the ARM code when it comes to the CPU. So, Flutter apps are not affected by any OS update or system customization, which spells stability.
  • Hot Reload. A unique feature to Flutter is where a developer can instantly see changes made to code with Hot Reload. What does this mean? Any updates are available to both designers and developers in seconds.
  • Rich Standard Library. For developers looking at using a rich standard library, Flutter is a great option. As it uses Dart, an object-oriented programming language, one can access a library including garbage collection, generics, strong typing, and async-awaits.
  • Custom Widgets. Yet, another compelling reason to use Flutter is the use of custom widgets. Developers get a flurry of widgets that help developers in their creation process.
  • Consistent UI. When you are looking at consistent UI across iOS and Android, Flutter widgets can help you. Developers can look forward to building powerful user interfaces for mobile apps.
  • Attract Investors with MVP. How about attracting more investors with an MVP? An MVP built on Flutter is compatible across different platforms and provides a high-quality user experience.
  • BLoC Architecture Pattern. For apps with a complex architecture and a significant amount of data, Flutter may be a great choice. It uses the BLoC (Business Logic Components) architecture pattern to eliminate delays in the app’s performance by utilizing async methods, structuring, and streams.
  • Pixel Perfect Apps. Yet another compelling reason to use Flutter is finding apps that look identical on all devices. So, for a pixel-perfect match, you can choose to use Flutter, which uses the Skia rendering engine, which supports iOS, Android, Windows, Ubuntu, and macOS.
