A simple Dart program to creates a tree-like visualization of the directory structure! 🎯

file_mapper.dart

import 'dart:io';
import 'dart:async';

void main() async {
  final rootDirectory = Directory.current;
  await printDirectoryTree(rootDirectory);
}

Future<void> printDirectoryTree(Directory directory, {String prefix = ''}) async {
  // List to store entries, sorted to ensure consistent output
  List<FileSystemEntity> entries;
  
  try {
    entries = await directory.list().toList();
    
    // Sort entries to make output more readable
    entries.sort((a, b) => a.path.compareTo(b.path));
  } catch (e) {
    print('Error accessing directory: $e');
    return;
  }

  for (int i = 0; i < entries.length; i++) {
    final entry = entries[i];
    final isLast = i == entries.length - 1;
    
    // Determine the appropriate connector
    final connector = isLast ? '└── ' : '├── ';
    
    // Skip hidden files and directories
    if (shouldSkipEntry(entry)) continue;

    // Get the relative path from the current directory
    final relativePath = entry.path.replaceFirst(directory.path + Platform.pathSeparator, '');
    
    // Print the current entry
    print('$prefix$connector$relativePath');
    
    // Recursively process directories
    if (entry is Directory) {
      await printDirectoryTree(
        entry, 
        prefix: prefix + (isLast ? '    ' : '│   ')
      );
    }
  }
}

bool shouldSkipEntry(FileSystemEntity entry) {
  final fileName = entry.path.split(Platform.pathSeparator).last;
  
  // List of directories and files to ignore
  final ignoredPatterns = [
    '.git',
    '.idea',
    '.vscode',
    'node_modules',
    'build',
    'out',
    'dist',
    '.dart_tool',
    '.packages',
    '.pub-cache',
    '.flutter-plugins',
    '.flutter-plugins-dependencies'
  ];

  return ignoredPatterns.any((pattern) => fileName.contains(pattern)) || 
         fileName.startsWith('.');
}
