Developers should know how to manage platform-specific code in cross-platform applications. In React Native, they must be able to create files with platform-specific extensions, like Component.ios.js and Component.android.js. For Flutter, they should know how to use Method Channels to call platform-specific code from Dart., Xamarin involves defining interfaces in the shared code and implementing them in the platform-specific projects.

How do you approach automated testing in cross-platform projects?

Automated testing ensures your app behaves consistently and correctly across different platforms. They must define the testing strategy, such as types of tests like Unit Tests, Integration Tests, UI Tests, and more. Then, developers should have knowledge of essential testing tools and frameworks. They must be able to set up a testing environment and write and organize tests.

How do you handle performance optimization in cross-platform applications?

A good knows different strategies to optimize cross-platform apps, which include Profiling and Benchmarking, Code Optimization through minimizing re-renders efficient data handling, and UI/UX optimization. Besides, they can use Platform-Specific Optimization techniques: for React Native, one can use libraries to optimize navigation, the Hermes JavaScript engine for better performance, and more. Besides, utilize the ‘flutter analyse’ command to identify performance issues in Flutter apps.

What security features do you incorporate in Cross-platform?

Coders can incorporate many security features in an app, like a Secure Authentication and Authorization System, Data Encryption Techniques, and Network Security, such as using HTTPS to secure API communications. Besides, one can even use Input Validation and sanitisation to prevent injection attacks, secure coding practices, and platform-specific security features.
