Common Mistakes to Avoid

Ignoring Dependencies

One common mistake is neglecting to manage dependencies properly. Beginners often overlook the importance of ensuring all required libraries are included, leading to runtime errors. To avoid this, always check your dependencies and ensure they are correctly listed in your project configuration.

Not Testing on Devices

Many new developers fail to test their applications on actual devices. This oversight can result in performance issues that are not apparent in emulators. To prevent this, regularly test your app on multiple devices to ensure compatibility and performance.

Overcomplicating Code

Beginners often write overly complex code, making it difficult to maintain. This can lead to bugs and increased development time. To avoid this, focus on writing clean, simple code and utilize comments to clarify complex sections for future reference.

Neglecting Documentation

Failing to document code is a frequent error among new developers. Without proper documentation, understanding and maintaining the code becomes challenging. To mitigate this, consistently document your code and maintain a clear README file for your projects.
