Top 15 Flutter Alternatives to Consider for Cross-Platform Apps

Last Updated
Flutter Alternatives

Cross-platform apps have witnessed great demand across a broader audience, coupled with the advantages they offer in crafting successful and efficient mobile applications. This catalyzed software development companies to facilitate mobile app development services.

Currently, many platforms are available for mobile app development, but Flutter certainly stands tall amongst them. But, if you are an aspiring developer, a start-up entrepreneur, or even a medium-scale enterprise, well, you landed at the right place. In this blog, we brought forward the top 15 Flutter alternatives that are ideally suited for developing cross-platform apps.

What is Flutter?

Flutter, developed and supported by Google, is a user interface tool kit (UI) designed for developers to create visually appealing interfaces for various screen sizes and devices.

Flutter offers pre-built widgets, such as rows, columns, and stacks, for easy app layout. It also borrows concepts from web design, such as paddings, centers, and margins, which can be used to design and develop for almost any device, as it requires a blank window.

Moreover, Flutter draws on this blank window to render animations, interactions, and changes. This eliminates the need for making-to-iOS apps, the Apple way, or the Android apps, the Android way. Instead, developers can use pre-widgets from Flutter, such as floating action buttons or linear processing indicators, and integrate them into their app. This makes it easier for developers to create visually appealing interfaces for various devices.

Features of Flutter

  • Open-source- It is available for free as it is an open-source framework. Moreover, there are many design options available.
  • Cross-platform- Flutter allows developers to use the single code database on different platforms.
  • Hot reload- Code changes can be easily reflected in the UI.
  • Accessible native features & SDKs- This feature makes the development process easy and delightful through third-party integration and platform APIs.
  • Minimal code- The system is developed using Dart programming language, which enhances start-up time, functionality, and performance through JIT and AOT compilation.
  • Widgets- Flutter can create complex widgets customized to the app’s needs. Moreover, it has pre-built widgets for developers’ usage.

Flutter app development can help you leverage emerging features and leave a lasting impact on the tech-savvy era.

What is the main purpose of Flutter?

The core purpose of Flutter is to allow developers to build interactive native applications for mobile, desktop, and web devices, particularly with a single code base. Flutter is the right choice for developing high-branded designs.
