Getting Started

1. Add this to your package's pubspec.yaml file:

dependencies:
  ...
  kterm: ^3.2.6

2. Create the terminal:

import 'package:kterm/xterm.dart';
...
terminal = Terminal();

Listen to user interaction with the terminal by simply adding a onOutput callback:

terminal = Terminal();

terminal.onOutput = (output) {
  print('output: $output');
}

3. Create the view, attach the terminal to the view:

import 'package:kterm/flutter.dart';
...
child: TerminalView(terminal),

4. Write something to the terminal:

terminal.write('Hello, world!');

Done!
