Build Status Key Listener

A library for transforming a stream of character code units into Key presses.

Quickstart

You can bind an input stream such as stdin to start listening for key presses.

new KeyListener(stdin).onKey(Key.A).listen((String keyName) {
    print('key $keyName was pressed');
});

Groups of keys can be monitored on a single stream.

new KeyListener(stdin).onKeySet([Key.A, Key.B]).listen((String keyName) {
    print('key $keyName was pressed');
});

// Or use one of the common key sets.
new KeyListener(stdin).onKeySet(KeySet.alphanumeric).listen((String keyName) {
    print('key $keyName was pressed');
});

If a key is missing from this library, its character codes will be emitted on KeyListener.onUnknownKey whenever the key is pressed.

Call KeyListener.deactivate when finished to close the input stream subscription.
