List files

Amplify Flutter v1 is deprecated as of April 30th, 2025. No new features or bug fixes will be added. Dependencies may become outdated and potentially introduce compatibility issues.

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 list all files uploaded under a given path.

This will list all files located under path album that:

  • have private access level
  • are in the root of album/ (the result doesn't include files under any sub path)
import 'package:amplify_flutter/amplify_flutter.dart';
import 'package:amplify_storage_s3/amplify_storage_s3.dart';
Future<void> listAlbum() async {
try {
String? nextToken;
bool hasNextPage;
do {
final result = await Amplify.Storage.list(
path: 'album/',
options: StorageListOptions(
accessLevel: StorageAccessLevel.private,
pageSize: 50,
nextToken: nextToken,
pluginOptions: const S3ListPluginOptions(
excludeSubPaths: true,
),
),
).result;
safePrint('Listed items: ${result.items}');
nextToken = result.nextToken;
hasNextPage = result.hasNextPage;
} while (hasNextPage);
} on StorageException catch (e) {
safePrint('Error listing files: ${e.message}');
rethrow;
}
}

Pagination is enabled by default. The default pageSize is 1000 if it is not set in the StorageListOptions.

You can also list all files under a given path without pagination by using the pluginOptions and S3ListPluginOptions.listAll() constructor.

This will list all public files (i.e. those with guest access level):

import 'package:amplify_flutter/amplify_flutter.dart';
import 'package:amplify_storage_s3/amplify_storage_s3.dart';
Future<void> listAllWithGuestAccessLevel() async {
try {
final result = await Amplify.Storage.list(
options: const StorageListOptions(
accessLevel: StorageAccessLevel.guest,
pluginOptions: S3ListPluginOptions.listAll(),
),
).result;
safePrint('Listed items: ${result.items}');
} on StorageException catch (e) {
safePrint('Error listing files: ${e.message}');
rethrow;
}
}
