Get file properties

Amplify Flutter v1 is now in Maintenance Mode until April 30th, 2025. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Flutter to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

You can get file properties and metadata without downloading the file using Amplify.Storage.getProperties.

import 'package:amplify_flutter/amplify_flutter.dart';
Future<void> getFileProperties() async {
try {
final result = await Amplify.Storage.getProperties(
key: 'example.txt',
safePrint('File size: ${result.storageItem.size}');
} on StorageException catch (e) {
safePrint('Could not retrieve properties: ${e.message}');
