Storage class

Provides access to file storage.

Pass storageQuery to set the path and adapter on the remote storage side.

Specify the local path in upload and upload the file. It is also possible to upload with real data instead of paths by using uploadWithBytes.

Uploaded files can be downloaded at download. In that case, cache the file by specifying the local cache path.

You can delete files on the remote side with delete.

ファイルストレージへのアクセス機能を提供します。

storageQueryを渡してリモートストレージ側のパスやアダプターの設定を行ってください。

uploadでローカルのパスを指定しファイルのアップロードを行います。 uploadWithBytesでパスではなく実データでアップロードすることも可能です。

アップロード済みのファイルをdownloadにてダウンロードすることが可能です。 その場合、ローカルのキャッシュのパスを指定してファイルをキャッシュします。

deleteでリモート側のファイルを削除することが可能です。

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
delete() → Future<void>
Deletes the file on the remote side specified by storageQuery.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
download([String? localRelativePath]) → Future<StorageValue?>
Download the file on the remote side specified by storageQuery to localRelativePath on the local side.
fetchDownloadURI() → Future<Uri>
Get the URI to download the file.
fetchPublicURI() → Future<Uri>
Get a URL that can be made public. Use this URI when you want to retrieve images, etc. using Image.network, etc.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
toString() → String
A string representation of this object.
inherited
upload(String localFullPath) → Future<StorageValue?>
Uploads a file located at localFullPath on the local to the remote location specified by storageQuery.
uploadWithBytes(Uint8List uploadFileByte) → Future<StorageValue?>
Uploads a file with the actual data in uploadFileByte to the location on the remote side specified by storageQuery.

Operators

operator ==(Object other) → bool
The equality operator.
