delete method

Future<void> delete(String bucket, String object, { String? generation, String? ifGenerationMatch, String? ifGenerationNotMatch, String? ifMetagenerationMatch, String? ifMetagenerationNotMatch, String? userProject, String? $fields, })

Deletes an object and its metadata.

Deletions are permanent if versioning is not enabled for the bucket, or if the generation parameter is used.

Request parameters:

bucket - Name of the bucket in which the object resides.

object - Name of the object. For information about how to URL encode object names to be path safe, see Encoding URI Path Parts.

generation - If present, permanently deletes a specific revision of this object (as opposed to the latest version, the default).

ifGenerationMatch - Makes the operation conditional on whether the object's current generation matches the given value. Setting to 0 makes the operation succeed only if there are no live versions of the object.

ifGenerationNotMatch - Makes the operation conditional on whether the object's current generation does not match the given value. If no live object exists, the precondition fails. Setting to 0 makes the operation succeed only if there is a live version of the object.

ifMetagenerationMatch - Makes the operation conditional on whether the object's current metageneration matches the given value.

ifMetagenerationNotMatch - Makes the operation conditional on whether the object's current metageneration does not match the given value.

userProject - The project to be billed for this request. Required for Requester Pays buckets.

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

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.
