Keymap

A keymap widget letting a developer easily allow end users to use keyboard shortcuts and an associated help screen overlay to any app.

Getting started

dependencies:
  keymap: <latest-version>

Features

• Easily add keyboard shortcuts to any widget tree
• Clear, readable help screen
• Insert at any point in the widget tree
• Respects application theme colors and fonts

Usage

Add a KeyMap widget to your tree in the build method

@override
Widget build(BuildContext context) {
  return KeyboardWidget(
    bindings: [
      KeyAction(LogicalKeyboardKey.keyA,'increment the counter', () {
        setState(() {
          count++;
        });}, isControlPressed: true),
      KeyAction(LogicalKeyboardKey.keyD, 'decrement the counter', () {
        setState(() {
          count--;
        });
      }, isAltPressed: true, isControlPressed: true),
    ],
    child: Column(
      children: [
        const Text('Up arrow for adding, down arrow to subtract'),
        Text('count: $count'),
      ],
    ),
  );
}

You can optionally set the number of columns for the text shown in the help screen

  @override
  Widget build(BuildContext context) {
    return KeyboardWidget(
      columnCount: 2,
      child: Scaffold(

This creates keyboard shortcuts that call the referenced methods and a help screen that can be called up by pressing F1 (or any key you choose):

It will shift colors to match your app's theme (here in dark mode)

Additional information

This is pre-beta and the API will probably change in the future.
