TOP 12 Tech facts and history of creation and versions about Flutter Development
- Flutter is an open-source UI software development kit created by Google in 2015.
- The main goal of Flutter is to enable developers to build beautiful and high-performance apps for multiple platforms using a single codebase.
- Flutter uses a reactive and declarative programming model, which means that the UI is built based on the current state of the app and automatically updates when the state changes.
- The first stable release of Flutter was in December 2018, and it has since gained popularity among developers worldwide.
- Flutter was developed by a team led by Chris Sells and Tim Sneath at Google.
- One of the groundbreaking features of Flutter is its hot reload functionality, which allows developers to see the changes they make in the code instantly reflected in the app without losing the current app state.
- Flutter apps are written in Dart, a programming language also developed by Google, which offers a modern and efficient syntax.
- Flutter provides a rich set of pre-designed widgets, allowing developers to create beautiful and consistent UIs across different platforms.
- Flutter has a growing community of developers and contributors, which means that there is a wealth of resources and support available for those using the framework.
- Flutter has been adopted by major companies such as Alibaba, Tencent, and Philips, showcasing its suitability for building production-ready apps.
- Google has been actively investing in Flutter’s development and improvement, regularly releasing new versions and updates to address user feedback and add new features.
- Flutter’s performance is comparable to that of native apps, thanks to its use of the Skia graphics engine and its ability to compile directly to machine code.
Pros & cons of Flutter
8 Pros of Flutter
- Fast Development: Flutter uses a hot reload feature that allows developers to see the changes instantly, resulting in faster development cycles.
- Single Codebase: With Flutter, you can write a single codebase for both iOS and Android platforms, reducing development time and effort.
- Beautiful UI: Flutter provides a rich set of customizable widgets that can create visually appealing and native-looking user interfaces.
- High Performance: Flutter’s architecture allows it to directly access platform-specific features, resulting in high-performance applications.
- Excellent Documentation: Google, the creator of Flutter, provides comprehensive and up-to-date documentation, making it easier for developers to learn and use the framework.
- Open-source: Flutter is an open-source framework, which means it has a large and active community that continuously contributes to its improvement.
- Wide Range of Libraries: Flutter has a vast ecosystem of libraries and packages that extend its functionality, allowing developers to add features easily.
- Strong Support for Testing: Flutter has built-in support for testing, making it easier to write and run tests for your applications.
8 Cons of Flutter
- Large File Size: Flutter applications have larger file sizes compared to native applications due to the inclusion of the Flutter engine.
- Learning Curve: If you are new to Flutter or Dart (the programming language used with Flutter), there might be a learning curve to overcome before becoming proficient.
- Limited Native Features: Although Flutter provides access to platform-specific features, it may not support all the native functionalities available on iOS and Android.
- Third-party Dependencies: As Flutter is a relatively new framework, there may be limited third-party dependencies available compared to more established frameworks.
- Less Mature Ecosystem: While Flutter has a growing ecosystem, it may not be as mature as other frameworks like React Native or native development.
- Plugin Compatibility: Some plugins in Flutter may not be compatible with all platforms, requiring additional effort to find alternatives or workarounds.
- Platform-specific Bugs: Due to the differences between iOS and Android, there may be platform-specific bugs or inconsistencies that developers need to address.
- Limited IDE Support: Although Flutter has good IDE support with tools like Android Studio and Visual Studio Code, it may not have the same level of support as native development.
Cases when Flutter does not work
- Unsupported Platforms: Flutter is primarily designed to work on iOS and Android platforms. However, it does not support other less popular platforms such as Windows Phone, Blackberry, and Tizen. If you are targeting any of these platforms, Flutter might not be the ideal choice for your development.
- Performance Limitations: While Flutter offers excellent performance for most applications, it may not be suitable for highly complex and computationally intensive applications. In such cases, using native development languages like Java or Kotlin for Android, or Swift or Objective-C for iOS, could provide better performance.
- Limited Native Feature Support: Although Flutter provides access to many native features and APIs, it may not support all the features available on a particular platform. This can be a limitation if your app heavily relies on specific platform-specific functionalities that are not yet available in Flutter.
- Large App Size: Flutter apps tend to have a larger file size compared to native apps. This is because Flutter apps include a complete Flutter engine, which adds to the overall size. If minimizing app size is a critical requirement for your project, you may need to consider native development instead.
- Learning Curve: Flutter uses a unique programming language called Dart, which might not be familiar to all developers. If your development team does not have prior experience with Dart, there will be a learning curve involved in adopting Flutter. This could impact the development timeline and productivity initially.
