问题 Is it possible to connect multiple devices with hot reload? Specifically, both Android and iOS emulators at the same time. 回答1: This works for me in Android Studio: Start both emulators Run your code with flutter run -d all Press r to hot reload 回答2: It doesn't work if you try to load it straight on Visual Code, but with few steps, you can code using VS Code or any other IDE and hot reload your code apart of the IDE Load iOS emulator in a terminal open -a Simulator Load Android emulator open
