Mixing native code with react-native

-

I'm just learning React Native for a cross platform app I am building.

I just need to know if it is (a) possible (b) supported (c) relatviely simple to mix native, platform specific code (java, swift, objc, etc.) into a react native project.

I want to do some pretty specific things with camera/hardware that will require writing some native code.

Hoping someone can point me in the right direction or at least tell me that what I want to do is supported by React Native before I dive in too far.

Yes to a, b, and c. See the official guides for iOS and Android.

I am trying to develop a flutter app which connects to the server and exchanges data using websocket. The server is in .Net Core and using Asp.Net Core Websockets to implement this functionality.

reinterpret_cast bug or UB? [duplicate]

-
This question already has an answer here: Observing weird behavior with 'auto' and std::minmax 1 answer structured bindings with std::minmax and rvalues 2 answers Consider following code: #include <cstdint> #include <algorithm> std::uintptr_t minPointer(void *first, void *second) { const auto pair = std::minmax( reinterpret_cast<std::uintptr_t>(first), reinterpret_cast<std::uintptr_t>(second) ); return pair.first; } and the assembly generated by GCC8 with -O3 on https://godbolt.org/z/qWJuV_ for minPointer: minPointer(void*, void*): mov rax, QWORD PTR [rsp-8] ret which clearly does not do what is intended by the code creator. Is this code causing some UB or is it GCC(8) bug? This is UB, but not for the reason you might think. The relevant signature o...
