How do you pass arguments from command line to main in Flutter/Dart?

问题

How would you run a command and pass some custom arguments with Flutter/Dart so they can then be accessed in the main() call such as:

flutter run -device [my custom arg]

So then I can access it with:

void main(List<String> args) {
  print(args.toString());
}

Thank you.

There is no way to do that, because when you start an app on your device there are also no parameters that are passed.

If this is for development, you can pass -t lib/my_alternate_main.dart to flutter run to easily switch between different settings
where each alternate entry-point file calls the same application code with different parameters or with differently initialized global variables.
