KeyMap class abstract

A collection of key bindings forming a key map.

Implement this interface to provide key bindings for help views.

Example

class MyKeyMap implements KeyMap {
  final up = KeyBinding.withHelp(['up', 'k'], '↑/k', 'move up');
  final down = KeyBinding.withHelp(['down', 'j'], '↓/j', 'move down');
  final quit = KeyBinding.withHelp(['q', 'ctrl+c'], 'q', 'quit');

  @override
  List<KeyBinding> shortHelp() => [up, down, quit];

  @override
  List<List<KeyBinding>> fullHelp() => [
    [up, down],
    [quit],
  ];
}
