There is a new crop of startups that are going full native, and not using things like React Native, and Flutter and other 'xchross platform' frameworks. They are falling out of the trend as they have the same problem that we have had since the Java Midlet times in the 90s, they tend to be: write once, debug everywhere.

So, keep using the native tools as close to the platform is smart strategy on the long term (as fads come and go).
