initLogging function

Implementation

void initLogging() async {
  // Log file
  var logfile = File(getLogFilePath());
  // Delete if file is larger than 1MB
  if (await logfile.exists() && await logfile.length() > 10 * 1024 * 1024) {
    await logfile.delete();
  }

  // File does not contain current version
  if (await logfile.exists() &&
      !(await logfile.readAsString()).contains(currentVersion)) {
    await logfile.delete();
  }

  // Check if file exists
  if (!await logfile.exists()) {
    await logfile.create();
    // Write header with version info and OS info
    await logfile.writeAsString(
        'WSL Manager v$currentVersion on ${Platform.operatingSystem} '
        '${Platform.operatingSystemVersion}\r\n\r\n'
        '============================================================'
        '\r\n\r\n');
