7. Limited access to native APIs: In cross-platform or hybrid apps, access to native APIs may be limited, limiting developers’ ability to utilize device-specific functionality fully.
8. Maintenance overheads: Maintaining a single codebase for multiple platforms can result in higher maintenance overheads due to the constant updates required for each platform’s specific features or changes.
9. Third-party dependencies: Many cross-platform and hybrid development tools rely heavily on third-party libraries and plugins, which can introduce additional complexities when updating or maintaining the app’s codebase.
Overall, maintaining good code quality in cross-platform or hybrid apps requires careful planning, constant communication among team members working on different platforms, thorough testing across all target devices, and keeping an eye out for platform-specific updates or limitations.
