Implementation

@override
Future<bool> run() async {
  // Check for template param
  String? tempName = templateName;
  final needsTemplate = tempName?.isEmpty ?? true;
  final closer = logger.printFixed("   👀 Checking templates");

  // If no template was specified
  if (needsTemplate) {
    tempName = await _selectTemplate();
    if (tempName == null || tempName.isEmpty) {
      return false; // Fail out, cannot proceed without a template
    }
  }

  // Validate provided template exists in list
  final tempList = await _getTemplateList();
  if (!tempList.contains(tempName)) {
    return false; // Fail out, cannot proceed with an invalid template
  }

  // Download selected template to temp dir
  final tempDir = await _downloadTemplate(name: tempName!);
  if (tempDir == null || tempDir.isEmpty) {
    return closer(false, 'Template download failed.');
  }

  // Deploy without overwriting existing files
  await _deployTemplateFiles(tempDir: tempDir);

  // Run the template installer
  await _installTemplate();

  // Delete temp dir and template repo
  if (tempDir.isNotEmpty) {
    await _deleteTemplateLocal(tempDir: tempDir);
  }

  return closer(true, tempName);
