Seamless Interoperability: Harnessing JNIGen and FFIGen
summary
Shows concrete bridges between Flutter and native code: method and event platform channels for simple calls like battery level, a camera/AR demo that accesses native permissions, and Pigeon generates type-safe Dart + Kotlin/Swift stubs from annotated APIs so you avoid handwriting handlers. Covers Dart FFI for C libraries, FFIgen using libclang to parse headers for iOS, and JNIgen produces intermediate C bindings for Android (experimental) that call Java via JNI so existing C C++ Rust or Java code becomes callable from Dart.
