Delete files with Cloud Storage on Flutter
Stay organized with collections
Save and categorize content based on your preferences.
After uploading files to Cloud Storage, you can also delete them.
Note: By default, a Cloud Storage bucket requires Firebase Authentication to
perform any action on the bucket's data or files. You can
change your Firebase Security Rules for Cloud Storage
to allow unauthenticated access. Since Firebase and your project's default
App Engine app share this bucket, configuring public access may make newly
uploaded App Engine files publicly accessible, as well. Be sure to restrict
access to your Cloud Storage bucket again when you set up Authentication.
Delete a File
To delete a file, first create a reference
to that file. Then call the delete()
method on that reference.
// Create a reference to the file to delete
final desertRef = storageRef . child ( "images / desert . jpg ");
// Delete the file
await desertRef . delete ();
Warning: Deleting a file is a permanent action! If you care about restoring
deleted files, make sure to back up your files, or
enable Object Versioning
on your Cloud Storage bucket.
Handle Errors
There are a number of reasons why errors may occur on file deletes,
including the file not existing, or the user not having permission
to delete the desired file. More information on errors can be found in the
Handle Errors section of the docs.
