Dart Reference v2.0

Create a bucket

Creates a new Storage bucket

Policy permissions required:
- buckets permissions: insert
- objects permissions: none
Refer to the Storage guide on how access control works

Parameters

REQUIRED

String

A unique identifier for the bucket you are creating.

bucketOptions

Optional

BucketOptions

A parameter to optionally make the bucket public.

public

REQUIRED

bool

The visibility of the bucket. Public buckets don't require an authorization token to download objects, but still require a valid token for all other operations. By default, buckets are private.

fileSizeLimit

Optional

String

Specifies the max file size in bytes that can be uploaded to this bucket. The global file size limit takes precedence over this value. The default value is null, which doesn't set a per bucket file size limit.

allowedMimeTypes

Optional

List<String>

Specifies the allowed mime types that this bucket can accept during upload. The default value is null, which allows files with all mime types to be uploaded. Each mime type specified can be a wildcard, e.g. image/*, or a specific mime type, e.g. image/png.


final String bucketId = await supabase
