kotlin sure does look better

Is it worthwhile to learn Flutter? Or just sticking to Kotlin is a sure bet for the next decade.

@IgorGanapolsky флаттер - это немного про другое, это ненативный гуй абстрагированный от платформы в первую очередь, рисует уи на предоставленном контексте вполне кроссплатформенно и главное быстро, как в играх подход в целом

IMHO both are much better than JAVA
