parseKeyBindings function

List<KeyBinding> parseKeyBindings(List<RawKeyBinding> raw)

Parse raw bindings (from [[keyboard.bindings]]) into Flutter bindings. Unknown keys are skipped (logged once); unknown actions become UnsupportedActionIntent; chars produces a SendEscapeIntent.

Implementation

List<KeyBinding> parseKeyBindings(List<RawKeyBinding> raw) {
  final out = <KeyBinding>[];
  for (final b in raw) {
    final key = _logicalForKeyName(b.key);
    if (key == null) {
      assert(() {
        debugPrint('flutter_alacritty: unknown key "${b.key}" in binding (skipped)');
        return true;
      }());
      continue;
    }
    final mods = _parseMods(b.mods);
    final activator = SingleActivator(
      key,
      control: mods.control,
      shift: mods.shift,
      alt: mods.alt,
      meta: mods.meta,
    );
    final Intent? intent;
    if (b.chars != null) {
      intent = SendEscapeIntent(utf8.encode(b.chars!));
    } else if (b.action != null) {
      intent = _intentForAction(b.action!);
    } else {
      intent = null;
    }
    if (intent == null) continue; // None/ReceiveChar/no action → no binding
    out.add(KeyBinding(activator, intent, mode: b.mode));
  }
  return out;
}
