How to use the gulp-notify.logLevel function in gulp-notify

var handleError = function (error) {
  var lineNumber = (error.lineNumber) ? 'LINE ' + error.lineNumber + ' -- ' : '';

  notify({
    title: 'Task Failed [' + error.plugin + ']',
    message: lineNumber + 'See console.'
  }, notify.logLevel(0)).write(error);

  // Inspect the error object
  //console.log(error);

  // Easy error reporting
  //console.log(error.toString());

  // Pretty error reporting
  var report = '';

  report += chalk.white.bgRed('TASK:') + ' [' + error.plugin + ']\n';
  report += chalk.white.bgRed('ERROR:') + ' ' + error.message + '\n';
  if (error.lineNumber) { report += chalk.red('LINE:') + ' ' + error.lineNumber + '\n'; }
  if (error.fileName)   { report += chalk.red('FILE:') + ' ' + error.fileName + '\n'; }

  console.error(report);
