Upgrade from Stable Version

All Storage S3 plugin APIs now return an operation object rather than the result object. The operation object provides more control over the in-flight request, such as cancellation, pause, and resume capabilities (varies by API). The result Future can be retrieved via the .result property.

How to upgrade

Upload example

See documentation for details API usage example.

// before
final result = await Amplify.Storage.uploadFile(
    local: exampleFile,
    key: 'ExampleKey',
);
print('Uploaded file key: ${result.key}')

// after
final result = await Amplify.Storage.uploadFile(
    localFile: exampleFile,
    key: 'ExampleKey',
).result;
print('Uploaded file key: ${result.uploadedItem.key}');

Download example

See documentation for details API usage example.

// before
final result = await Amplify.Storage.downloadFile(
  key: 'ExampleKey',
  local: file,
);
print('Downloaded local file path: ${result.file.path}')


// after
final result = await Amplify.Storage.downloadFile(
  key: 'ExampleKey',
  localFile: file,
).result;
print('Downloaded file key: ${result.downloadedItem.key}');
print('Downloaded local file path: ${result.localFile.path}');

List example

See documentation for details API usage example.

// before
final result = await Amplify.Storage.list();
print('Listed items: ${result.items}');

// after
final result = await Amplify.Storage.list().result;
print('Listed items: ${result.items}');
print('Are there more items can be listed? ${result.hasNextPage}');
print('List nextToken: ${result.nextToken}');

Remove example

See documentation for details API usage example.

// before
final result = await Amplify.Storage.remove(
  key: key,
);
print('Removed file key: ${result.key}');

// after
final result = await Amplify.Storage.remove(
  key: key,
).result;
print('Removed file key: ${result.removedItem.key}');
