What Makes Flutter Unique?

Unlike maintaining separate libraries in Java, JavaScript, Swift, Kotlin, and all these tech stacks for developing a single application on multiple OSes, Flutter covers all your code in a single language.

And this results in saving time, effort, stress, and more. Here are a few characteristics of Flutter that make it unique:

  • Rich UI and native performance: Flutter offers you widgets, which are a set of pre-designed UI components that can be customized to maintain the aesthetic identity of your branding. These widgets allow you to maintain native-like performance on cross-platforms, facilitating high performance and smooth animations.
  • Integration capabilities: Flutter provides easy integration capabilities with third-party libraries and existing native codes. Integrations such as platform-specific APIs, Firebase, REST APIs, State management libraries, In-app purchases, Payment gateways, etc. are done in a hassle-free manner.
  • Open-source: Flutter is entirely free to use with multiple integration capabilities, be it video, voice, chat, advertisements, and more. Moreover, Flutter developers are active in enhancing the framework, fixing bugs, adding new features, creating additional packages and plugins, etc. Due to its wide range of community support, Flutter stands alone in upgrading user experiences.

These are some of the key points that make Flutter unique. Yet there are a lot more reasons for a developer to build their video call app in Flutter. 

The Challenges of Making Flutter Video Chat Applications

Even though it offers enormous benefits and unique features, Flutter does have some challenges in making video chat apps. Such as

  • Lack of libraries: As a developer, you might need third-party libraries for certain functionalities in your software. But Flutter fails in it as of now. Since it is a new framework constantly evolving and improving, it currently doesn’t offer third-party library support, which is free and open-source.
  • Continuous Integration: Integrating Flutter with continuous integration (CI) platforms like Github, Travis, Jenkins, etc. can be challenging. You have to create and maintain separate scripts for building, testing, and deploying Flutter apps in the continuous integration process.
  • Hanging iOS Features: Flutter is backed by Google, which left the supporting features of iOS hanging. It doesn’t offer proper support on iOS, such as deleting the EXIF data while taking pictures, which might result in improper orientation, location, and gamma. Even some unique iOS accessibility features like voiceover, guided access, captioning, and audio descriptions are not supported in Flutter.

As a fast-growing software, Flutter should be focusing on these cons to make it to the top. But currently, these issues are being faced by developers mostly while building a secure chat application in Flutter with a video call feature.

Top 6 Flutter Video Call App Features in 2024

Flutter facilitates advanced and modern features for video call apps. Yet here are the top six features that rule the market:
