It's not difficult to switch between mobile stacks. It's just companies make you believe that it is, to promote a "one codebase efficiency" mantra. For me, to be efficient with cross-platform solutions, you need a deeper knowledge with the underlying native frameworks. I started with Blackberry SDK plugin with Eclipse, then to Android, Windows Mobile (UWP) and iOS in that order. Majority of those projects I have worked are written in native. It's not that hard to switch since you can find familiar concepts in each frameworks and stacks. Of course, I have been also part with cross-platforms solutions but it just cannot cope up with the yearly updates and deprecation especially if your apps are critical.
