Can we convert Java code to Swift?

You cannot translate Java to Swift automatically . There are too many differences. To speed up an application, you have to find out which parts of the code consume most of the time, then redesign the program in such a way that it does it more efficiently.

The engine’s C and C++ code are compiled with Android’s NDK. The Dart code (both the SDK’s and yours) are ahead-of-time (AOT) compiled into a native, ARM and x86 libraries . Those libraries are included in a “runner” Android project, and the whole thing is built into an APK.

Flutter uses a flexible system that allows you to call platform-specific APIs in a language that works directly with those APIs: Kotlin or Java on Android .
