Shell commands in Flutter

Question

I am developing a desktop UI in Flutter and I need to create buttons to execute shell commands.

I already can execute some commands simple such as ls -l and it shows its results nicely in the console.

However I need a way to show the results in the main app and not in the console, I have tried the snackbar but it is not so nice and it does not get the outputs from other commands that gives dynamic outputs.

I would like to watch dynamic outputs such as tail -f and top.

How could I open a new window in the flutter app to show the execution of a command?

For now, I have this:

class LsButton extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: RaisedButton(
          onPressed: () {
            Process.run('ls', ['-l']).then((ProcessResult results) {
              Flushbar(
                title: "Output",
                message: results.stdout,
                duration:  Duration(seconds: 15),
              )..show(context);
            });
          },
          child: Text('Show dir contents!',
          style: TextStyle(
            fontSize: 10,
          ),)
      ),
    );
  }}

Solution

Flutter doesn't yet support multiple windows, so currently if you want to do that you'd have to do it via native code, controlled via platform channels.
