removeFilesSync static method

void removeFilesSync(String path, { Pattern? pattern, })

根据指定条件删除文件

TODO 需要实现异步方法

path 需要删除的路径 pattern 过滤器

Implementation

static void removeFilesSync(
  String path, {
  Pattern? pattern,
}) {
  if (!existsSync(path)) {
    return;
  }
  void fnDel(FileSystemEntity entity) {
    bool needRemove = true;
    final p = entity.path;
    if (pattern != null) {
      final size = pattern.allMatches(p).length;
      needRemove = size > 0;
    }
    if (needRemove) {
      Logger.info('[Remove]', p);
      entity.deleteSync();
    }
  }

  final type = typeSync(path);
  if (type == FileSystemEntityType.file) {
    fnDel(File(path));
  } else if (type == FileSystemEntityType.directory) {
    // 读取目录，并拿到子项
    final files = Directory(path).listSync();
    // 循环执行，如果是文件执行删除方法，如果目录则执行递归
    for (final f in files) {
      if (isFileSync(f.path)) {
        fnDel(f);
      } else if (isDirectorySync(f.path)) {
        removeFilesSync(f.path, pattern: pattern);
      }
    }
  }
}
