dart-ffi

问题 I am developing a package in C++ to be used in a Flutter app (and therefore in Dart), using dart::ffi and I was wondering if there was a better way to debug (step by step, variable watch, that sort of things) the C++ code, other than logging messages. I've tried both in Android Studio and VS Code, with no success. 回答1: Android Studio (or VS Code) doesn't support native (C/C++) code debugging while in Flutter mode (yet). However, there is a workaround! In the project tree, right-click the

问题 What is difference between writing code using dart:ffi in flutter or writing code with the method chanel in flutter. 回答1: dart:ffi is used to call C/C++ code - typically to reuse an existing C/C++ library - often a CPU intensive operation, like codecs, image processing, cryptography. The C code has limited access to the system APIs. Method channels are used to access the underlying environment and its APIs - so are written in Kotlin or Java on Android, Swift or Objective C on iOS and macOS
