final
endPoint → String
endPoint is a host name or an IP address.
final
hashCode → int

maximum part size for multipart uploads.
final
maxObjectSize → int

Methods

bucketExists(String bucket) → Future<bool>
Checks if a bucket exists.
completeMultipartUpload(String bucket, String object, String uploadId, List<CompletedPart> parts) → Future<String>
Complete the multipart upload. After all the parts are uploaded issuing this call will aggregate the parts on the server into a single object.
copyObject(String bucket, String object, String srcObject, [CopyConditions? conditions]) → Future<CopyObjectResult>
Copy the object.
findUploadId(String bucket, String object) → Future<String?>
Find uploadId of an incomplete upload.
getBucketNotification(String bucket) → Future<NotificationConfiguration>
Return the list of notification configurations stored in the S3 provider
getBucketPolicy(dynamic bucket) → Future<Map<String, dynamic>?>
Get the bucket policy associated with the specified bucket. If objectPrefix is not empty, the bucket policy will be filtered based on object permissions as well.
getBucketRegion(String bucket) → Future<String>
Gets the region of bucket. The region is cached for subsequent calls.
getObject(String bucket, String object) → Future<MinioByteStream>
get a readable stream of the object content.
getObjectACL(String bucket, String object) → Future<AccessControlPolicy>
getPartialObject(String bucket, String object, [int? offset, int? length]) → Future<MinioByteStream>
get a readable stream of the partial object content.
initiateNewMultipartUpload(String bucket, String object, Map<String, String>? metaData) → Future<String>
Initiate a new multipart upload.
listAllObjects(String bucket, {String prefix = '', bool recursive = false}) → Future<ListObjectsResult>
Returns all Objects in a bucket. This is a shortcut for listObjects. Use listObjects to list buckets with a large number of objects.
listAllObjectsV2(String bucket, {String prefix = '', bool recursive = false}) → Future<ListObjectsResult>
Returns all Objects in a bucket. This is a shortcut for listObjectsV2. Use listObjects to list buckets with a large number of objects. This uses ListObjectsV2 in the S3 API. For backward compatibility, use listAllObjects instead.
listBuckets() → Future<List<Bucket>>
List of buckets created.
listenBucketNotification(String bucket, {String? prefix, String? suffix, List<String>? events}) → NotificationPoller
Listen for notifications on a bucket. Additionally one can provider filters for prefix, suffix and events. There is no prior set bucket notification needed to use this API. This is an MinIO extension API where unique identifiers are regitered and unregistered by the server automatically based on incoming requests.
listIncompleteUploads(String bucket, String prefix, [bool recursive = false]) → Stream<IncompleteUpload>
Returns a stream that emits objects that are partially uploaded.
listIncompleteUploadsQuery(String bucket, String prefix, String? keyMarker, String? uploadIdMarker, String delimiter) → Future<ListMultipartUploadsOutput>
Called by listIncompleteUploads to fetch a batch of incomplete uploads.
listObjects(String bucket, {String prefix = '', bool recursive = false}) → Stream<ListObjectsResult>
Returns all Objects in a bucket. To list objects in a bucket with prefix, set prefix to the desired prefix.
listObjectsQuery(String bucket, String prefix, String? marker, String delimiter, int? maxKeys) → Future<ListObjectsOutput>
list a batch of objects
listObjectsV2(String bucket, {String prefix = '', bool recursive = false, String? startAfter}) → Stream<ListObjectsResult>
Returns all Objects in a bucket. To list objects in a bucket with prefix, set prefix to the desired prefix. This uses ListObjectsV2 in the S3 API. For backward compatibility, use listObjects instead.
listObjectsV2Query(String bucket, String prefix, String? continuationToken, String delimiter, int? maxKeys, String? startAfter) → Future<ListObjectsV2Output>
listObjectsV2Query - (List Objects V2) - List some or all (up to 1000) of the objects in a bucket.
listParts(String bucket, String object, String uploadId) → Stream<Part>
Get part-info of all parts of an incomplete upload specified by uploadId.
listPartsQuery(String? bucket, String? object, String? uploadId, int? marker) → Future<ListPartsOutput>
Called by listParts to fetch a batch of part-info
makeBucket(String bucket, [String? region]) → Future<void>
Creates the bucket bucket.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
presignedGetObject(String bucket, String object, {int? expires, Map<String, String>? respHeaders, DateTime? requestDate}) → Future<String>
Generate a presigned URL for GET
presignedPostPolicy(PostPolicy postPolicy) → Future
presignedPostPolicy can be used in situations where we want more control on the upload than what presignedPutObject() provides. i.e Using presignedPostPolicy we will be able to put policy restrictions on the object's name bucket expiry Content-Type
presignedPutObject(String bucket, String object, {int? expires}) → Future<String>
Generate a presigned URL for PUT. Using this URL, the browser can upload to S3 only with the specified object name.
presignedUrl(String method, String bucket, String object, {int? expires, String? resource, Map<String, String>? reqParams, DateTime? requestDate}) → Future<String>
Generate a generic presigned URL which can be used for HTTP methods GET, PUT, HEAD and DELETE
putObject(String bucket, String object, Stream<Uint8List> data, {int? size, int? chunkSize, Map<String, String>? metadata, void onProgress(int)?}) → Future<String>
Uploads the object. Returns the ETag of the uploaded object.
removeAllBucketNotification(String bucket) → Future<void>
Remove all bucket notification
removeBucket(String bucket) → Future<void>
Remove a bucket.
removeIncompleteUpload(String bucket, String object) → Future<void>
Remove the partially uploaded object.
removeObject(String bucket, String object) → Future<void>
Remove the specified object.
removeObjects(String bucket, List<String> objects) → Future<void>
Remove all the objects residing in the objectsList.
setBucketNotification(String bucket, NotificationConfiguration config) → Future<void>
setBucketPolicy(String bucket, [Map<String, dynamic>? policy]) → Future<void>
Set the bucket policy on the specified bucket.
setObjectACL(String bucket, String object, String policy) → Future<void>
statObject(String bucket, String object) → Future<StatObjectResult>
Stat information of the object.
toString() → String
A string representation of this object.

The equality operator.
