Basic Usage

import 'package:disk_usage/disk_usage.dart';

// Get total disk space
final totalSpace = await DiskUsage.space(DiskSpaceType.total);
print('Total space: $totalSpace bytes');

// Get free disk space
final freeSpace = await DiskUsage.space(DiskSpaceType.free);
print('Free space: $freeSpace bytes');

Convenience Methods

// Get total space (convenience method)
final totalSpace = await DiskUsage.totalSpace();

// Get free space (convenience method)
final freeSpace = await DiskUsage.freeSpace();

With Custom Path

// Get disk space for a specific path
final totalSpace = await DiskUsage.space(DiskSpaceType.total, '/custom/path');
final freeSpace = await DiskUsage.space(DiskSpaceType.free, '/custom/path');

Error Handling

try {
  final totalSpace = await DiskUsage.space(DiskSpaceType.total);
  if (totalSpace != null) {
    print('Total space: $totalSpace bytes');
  } else {
