When starting a new Flutter project in Android Studio, it gives you the choice of android language between Java or Kotlin. so the question is:
Is my choice affecting any type of performance or compatibility? Application size or Error-handling ? Is there any difference at all ?
Same goes for Objective-C vs Swift ?
Use
Android -> Kotlin
IOS -> Swift
because these are the languages that apple and google recommend.
Pick Kotlin and Swift as they are the newer and more preferred languages of those platforms
Although it really doesn't matter. You won't use either of those languages much. You will mostly interact with Dart
My Recommended is to Go for kotlin in Android. and For IOS go for Swift
One of the best reason is Google and Apple recommended and preferred this languages.
Second things kotlin is very optimized language so it's reduce the codes and make your dart file more clear to understand.
Third things kotlin supports multiple platforms. where java have some limitations in it.
But at the end both of the language is very useful to developed a single app.
Note : If you start for Application development in native Android, First Go for Java language then you have to learn about kotlin. because Java is a Base of Native Android
