How to determine if path is file or folder using Dart

I need to determine if a path is folder or a file using Dart.

The FileSystem class has methods: isDirectory and isFile.

I don't understand how to access FileSystem class and these class methods.

Could you please provide your suggestions.

Thank You

You can try something like that:

import 'dart:io';

Future<String> isFileOrDirectory(String path) async {
  try {
    final isDirectory = await Directory(path).exists();
    final isFile = await File(path).exists();

    if (isDirectory) {
      return 'directory';
    } else if (isFile) {
      return 'file';
    } else {
      return 'error';
    }
  } catch (e) {
    return 'error';
  }
}

void main() async {
  String result = await isFileOrDirectory('./mydirectory');
  print(result);
}

Feel free to adapt this code to your needs

===EDIT===

According to @pskink, you can also use this:

Future<String> isFileOrDirectory(String path) async {
  FileSystemEntityType type = await FileSystemEntity.type(path);

  return type.toString();
}

void main() async {
  String result = await isFileOrDirectory('./mydirectory');
  print(result);
}
