Calling C/C++ from Flutter - Richard Heap (Flutter Week) 

Just want to clarify that is possible to call Rust code using FFI if it exposes a function using "extern C", i.e. it generates a C-like symbol in the final library.

Great video! Very well explained how ffi works, and specially since there aren't that many out there. One question though, what about the implementation of the write() method? I couldn't find it in the video

Thank you for this well explained demonstration. There are many difficulties when trying to do this in practice. I had this issue with the typedefs: This compiles fine as the lib.lookup to NativeFunction resolves typedef native_messagebus_dispose = Int8 Function(Pointer); typedef dart_messagebus_dispose = int Function(Pointer); _messagedispose = myLib.lookup('messagebus_dispose') .asFunction(); however this does not resolve typedef native_messagebus_dispose = Void Function(Pointer); typedef dart_messagebus_dispose = Void Function(Pointer); How to resolve such method types?

Does this work for flutter desktop too?

callbacks are also supported: github.com/dart-lang/sdk/issues/34452#issuecomment-638666612

i'm trying to build flutter linux desktop application that with opening camera and taking picture functionalities. I wrote my native code that is working fine if i run itself without dart. it is not working at all when i integrate it. Is it even possible to build it?

can you do ffi for web with webassembly?
