Flutter: getPublicUrl

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

Parameters

• path

  (Required)

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

• download

  (Optional)

  Triggers the file to be downloaded rather than opened in the browser. Use `DownloadBehavior.withOriginalName` to keep the original file name or `DownloadBehavior.named('custom.png')` to override it.

• transform

  (Optional)

  Transform the asset before serving it to the client.

Examples

Returns the URL for an asset in a public bucket

final String publicUrl = supabase
  .storage
  .from('public-bucket')
  .getPublicUrl('avatar1.png');

With transform

final String publicUrl = await supabase
  .storage
  .from('public-bucket')
  .getPublicUrl(
    'avatar1.png',
    transform: TransformOptions(
      width: 200,
      height: 200,
    ),
  );

Trigger download

final String publicUrl = supabase
  .storage
  .from('public-bucket')
  .getPublicUrl(
    'avatar1.png',
    download: DownloadBehavior.withOriginalName,
  );
