   @override
    Widget build(BuildContext context) {
        return Scaffold(
            appBar: AppBar(
                title: const Text('Terminal'),
            ),
            body: TerminalView(Terminal())
        );

I use Android Studio from Flatpak, Flutter from snap & Ubuntu 22.04.4 LTS.

It needs a backend shell to work. Xterm is just a front-end framework. Use the flutter_pty package to connect Xterm with the Android shell.

Otherwise, you need to bundle an arm64 cross-compiled bash binary with your app using jniLibs. Then, use flutter_pty to connect with your custom bash. It isn't very easy, so the first method is recommended.
