Dart Reference v2.0

Retrieve public URL

Retrieve URLs for assets in public buckets

The bucket needs to be set to public, either via updateBucket() or by going to Storage on supabase.com/dashboard, clicking the overflow menu on a bucket and choosing "Make public"
Policy permissions required:
- buckets permissions: none
- objects permissions: none
Refer to the Storage guide on how access control works

The path and name of the file to generate the public URL for. For example folder/image.png.

int

The width of the image in pixels.

height

Optional

int

The height of the image in pixels.

ResizeMode

Specifies how image cropping should be handled when performing image transformations. Defaults to `ResizeMode.cover`.

quality

Optional

int

Set the quality of the returned image. A number from 20 to 100, with 100 being the highest quality. Defaults to 80

RequestImageFormat

Specify the format of the image requested. When using 'origin' we force the format to be the same as the original image. When this option is not passed in, images are optimized to modern image formats like Webp.
