      <String, Object>{'languageTag': languageTag},
    );
    return ok ?? false;
  } on MissingPluginException {
    throw UnsupportedError(
      'Switching the keyboard language is not supported on this platform.',
    );
  } on PlatformException catch (e) {
    if (e.code == 'unsupported') {
      throw UnsupportedError(
        e.message ??
            'Switching the keyboard language is not supported on this '
                'platform.',
      );
