get method

Future<Object> get(String fileId, { bool? acknowledgeAbuse, String? includeLabels, String? includePermissionsForView, String? projection, String? revisionId, bool? supportsAllDrives, bool? supportsTeamDrives, bool? updateViewedDate, String? $fields, DownloadOptions downloadOptions = commons.DownloadOptions.metadata, })

Gets a file's metadata or content by ID.

If you provide the URL parameter alt=media, then the response includes the file contents in the response body. Downloading content with alt=media only works if the file is stored in Drive. To download Google Docs, Sheets, and Slides use [files.export](/drive/api/reference/rest/v2/files/export) instead. For more information, see [Download & export files](/drive/api/guides/manage-downloads).

Request parameters:

fileId - The ID for the file in question.

acknowledgeAbuse - Whether the user is acknowledging the risk of downloading known malware or other abusive files.

includeLabels - A comma-separated list of IDs of labels to include in the labelInfo part of the response.

includePermissionsForView - Specifies which additional view's permissions to include in the response. Only published is supported.

projection - Deprecated: This parameter has no function. Possible string values are:

• "BASIC" : Deprecated.
• "FULL" : Deprecated.

revisionId - Specifies the Revision ID that should be downloaded. Ignored unless alt=media is specified.

supportsAllDrives - Whether the requesting application supports both My Drives and shared drives.

supportsTeamDrives - Deprecated: Use supportsAllDrives instead.

updateViewedDate - Deprecated: Use files.update with modifiedDateBehavior=noChange, updateViewedDate=true and an empty request body.

$fields - Selector specifying which fields to include in a partial response.

downloadOptions - Options for downloading. A download can be either a Metadata (default) or Media download. Partial Media downloads are possible as well.

Completes with a

• File for Metadata downloads (see downloadOptions).

• commons.Media for Media downloads (see downloadOptions).

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.
