Implementation

File? getInnoSetupExec({bool throwIfNotFound = true}) {
  if (!Directory(p.joinAll(innoSysDirPath)).existsSync() &&
      !Directory(p.joinAll(innoUserDirPath)).existsSync()) {
    if (throwIfNotFound) {
      CliLogger.exitError("Inno Setup is not detected in your machine, "
          "checkout our docs on how to correctly install it:\n"
          "${CliLogger.sLink(innoDownloadStepLink, level: CliLoggerLevel.two)}");
    }
    return null;
  }

  final sysExec = p.joinAll([...innoSysDirPath, "ISCC.exe"]);
  final sysExecFile = File(sysExec);
  final userExec = p.joinAll([...innoUserDirPath, "ISCC.exe"]);
  final userExecFile = File(userExec);

  if (sysExecFile.existsSync()) return sysExecFile;
  if (userExecFile.existsSync()) return userExecFile;

  if (throwIfNotFound) {
    CliLogger.exitError("Inno Setup installation in your machine is corrupted "
        "or incomplete, checkout our docs on how to correctly install it:\n"
        "${CliLogger.sLink(innoDownloadStepLink, level: CliLoggerLevel.two)}");
  }
  return null;
