1. Preface

The article 'Ultimate Cross-Platform Framework Selection: Flutter vs. React Native' provides a comprehensive comparison of React Native and Flutter from multiple perspectives. In today's diverse software development landscape, both Electron and Flutter are popular frameworks used by developers to build cross-platform desktop and mobile applications. Electron is primarily used for creating desktop applications, while Flutter was originally designed for mobile app development but now also supports desktop and web. This article will provide a comprehensive comparison of Electron and Flutter across multiple dimensions to help developers choose the right framework based on project requirements.
In the era of AI, using AI to generate high-quality code is a standout feature. Take AI Design for example, a tool that effortlessly converts screenshots into editable Figma UI designs. Simply upload an image of any app or website, and it smoothly handles the conversion process. Additionally, AI Code enhances this functionality by facilitating Figma-to-Code translations, supporting a wide range of platforms including Flutter, React, HTML, CSS, Vue, Android, iOS, macOS, etc., and ensures the creation of highly accurate code.

2. Technology Stack and Language

Electron:
Electron is a framework for building desktop applications using web technologies. It combines Chromium (an open-source web browser project) and Node.js, allowing developers to use HTML, CSS, and JavaScript to create applications. Electron's advantage is that it enables web developers to build desktop apps without having to learn new languages or frameworks.

Flutter:
Flutter is a UI toolkit from Google for creating high-performance, high-fidelity cross-platform applications from a single codebase that compiles into native code. It uses the Dart language, which is a client-optimized language developed by Google for fast development and execution. Flutter is characterized by its own rendering engine, which allows for smooth and consistent UI experiences.

3. Performance

Electron:
Electron apps typically consume more resources because each Electron app runs a full instance of the Chromium browser. This means that even the simplest Electron app can occupy a significant amount of memory and CPU resources, especially when creating multiple windows or complex applications. Performance issues often need to be addressed through optimization and careful design.

Key points summarized:

• Electron uses the Chromium engine to render application interfaces, meaning it can provide a powerful web experience, including high-quality web page rendering.
• Due to Chromium's sandboxing mechanism, Electron applications perform well in terms of security.
• However, due to the use of web technologies, Electron applications tend to consume more system resources, particularly in terms of memory and startup time.

Flutter:
Flutter apps generally perform better in terms of performance because they compile directly into native code. Flutter's rendering engine and framework code are pre-compiled, which typically makes Flutter apps faster in startup time and running efficiency compared to Electron apps.

Key points summarized:

• Flutter uses the Dart programming language and its own rendering engine to render interfaces, typically with excellent performance.
• Compared to Electron, Flutter applications are usually more lightweight, start up faster, and perform well on mobile devices.
• Since Flutter comes with its own UI widgets, the appearance and performance of applications are usually more consistent, which helps provide a better user experience.

4. User Interface

Electron:
The user interface of Electron applications is built using web technologies, which means developers can leverage the flexibility of HTML and CSS for design. However, this can also lead to consistency issues across different operating systems due to varying web rendering and behaviors.

Flutter:
Flutter offers a rich set of pre-made components (Widgets), allowing developers to create highly customized user interfaces. A major advantage of Flutter is its "write once, run everywhere" capability, ensuring consistent user experiences across all platforms.

5. Development Experience

Electron:
The development experience with Electron is very close to web development, making it very accessible for developers familiar with JavaScript, HTML, and CSS. Since Electron is based on Node.js, developers can easily access a vast array of npm modules. The Electron community provides a wealth of templates and tools to help developers get started quickly with projects.

Flutter:
Flutter uses the Dart language, which may require developers to invest time to learn, especially for those unfamiliar with Dart. However, once mastered, Flutter offers a fast hot reload feature that greatly enhances development efficiency and experience.

6. Development Tools

Electron:

• Electron typically uses web development tools familiar to developers, such as VS Code, WebStorm, etc.
• There is a wealth of debugging tools and plugins, making it relatively easy for front-end developers to get started.

Flutter:

• Flutter uses the Dart programming language, and developers need to learn Dart and the Flutter framework, which may take some time to adapt.
• Flutter provides a wealth of tools, such as Flutter DevTools, for debugging and performance analysis.

7. Community and Ecosystem

Electron:

• Electron has a strong ecosystem, and since it is based on web technologies, it can easily utilize various libraries and tools from the web.
• JavaScript libraries can be used to implement various functionalities, such as file operations, network requests, etc.
• Electron has a very mature community, with many popular desktop applications built using Electron, such as Visual Studio Code, Slack, and Atom. This provides developers with a wealth of learning resources, plugins, and third-party libraries.

Flutter:
Although Flutter is a relatively new framework, its community is growing rapidly. Google's strong support for Flutter and the ever-increasing library of packages and plugins are enriching its ecosystem. Flutter's community is active, providing a wealth of resources and support, including plugins, tutorials, and code samples.

8. Cross-Platform Capability

Electron:

• Electron is primarily used for desktop application development, supporting Windows, macOS, and Linux.
• While mobile applications can be achieved with additional work, it is not its primary use.

Flutter:
Flutter was originally designed for mobile app development, supporting iOS and Android. With recent updates, Flutter now also supports web, Windows, macOS, and Linux, becoming a truly all-platform framework. This makes Flutter a very attractive choice, especially for developers who want their applications to run on multiple platforms.

9. Packaging and Distribution

Electron:
Electron applications can be packaged and distributed using tools like Electron Forge, Electron Builder, etc. These tools support creating installers for different operating systems and can be integrated into automated build processes.

Flutter:
Flutter provides official command-line tools for compiling and packaging applications. For mobile apps, developers can upload them to the App Store or Google Play. For desktop applications, Flutter supports generating executables for the respective platforms, which can be provided to users through various distribution channels.

10. Conclusion

Electron and Flutter are both powerful frameworks for developing cross-platform applications, but they are suited for different types of projects. If you want to quickly develop desktop applications, especially those based on web technologies, then Electron might be the better choice. However, if you need high performance, consistent user experiences, and plan to deploy applications across multiple platforms, then Flutter might be more suitable for your needs. Developers should consider the performance requirements of the application, target platforms, development time, and the technical background of the individual or team when choosing a framework.
