FilePickerCross class - file_picker_cross library

Constructors

FilePickerCross(Uint8List _bytes, {String? path, FileTypeCross type = FileTypeCross.any, String fileExtension = ''})

Properties

directory → String: Returns the directory the file is located in. This it typically everything before the last / or \. Note: Even on Windows and web platforms, where file paths are typically presented using \ instead of /, the path's single directories are separated using /.
no setter
fileExtension → String: The allowed file extension of the file to be selected
final
fileName → String?: Returns the name of the file. This typically is the part of the path after the last / or \.
no setter
hashCode → int: The hash code for this object.
no setterinherited
length → int: Returns the file's length in bytes
no setter
path → String?: Returns the path the file is located at
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
type → FileTypeCross: The allowed FileTypeCross of the file to be selected
final

Methods

exportToStorage({String? subject, String? text, Rect? sharePositionOrigin, String? fileName, bool share = true}) → Future<String?>: Export the file to the external storage. This shows a file dialog allowing to select the file name and location and will return the finally selected, absolute path to the file.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
saveToPath({required String path}) → Future<bool>: Save the file to an internal path. This does not allow you to save the file to the device's public storage like Documents, Downloads or Photos but saves the FilePickerCross in an app specific, internal folder for later access by this app only. To export a file to the local storage, use exportToStorage instead.
toBase64() → String: Returns the file as base64-encoded String.
toMultipartFile({String? filename}) → MultipartFile: Returns the file as MultiPartFile for use with tha http package. Useful for file upload in apps.
toString() → String: Returns a sting containing the file contents of plain text files. Please use it in a try {} catch (e) {} block if you are unsure if the opened file is plain text.
override
toUint8List() → Uint8List: Returns the file as a list of bytes.

Operators

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

Static Methods

delete({required String path}) → Future<bool>: finally deletes a file stored in the given path of your application's fake filesystem
fromInternalPath({required String path}) → Future<FilePickerCross>: Creates a FilePickerCross from a local path. This does not allow you to open a file from the local storage but only a file previously saved by saveToPath. If you want to open the file to the shared, local memory, use importFromStorage instead.
importFromStorage({FileTypeCross type = FileTypeCross.any, String fileExtension = ''}) → Future<FilePickerCross>: Shows a dialog for selecting a file from your device's internal storage. If thee selected file is a Null byte, a NullThrownError is thrown. If the file selection was canceled by the user, a FileSelectionCanceledError is thrown.
importMultipleFromStorage({FileTypeCross type = FileTypeCross.any, String fileExtension = ''}) → Future<List<FilePickerCross>>: Imports multiple files into your application. See importFromStorage for further details.
listInternalFiles({Pattern? at, Pattern? name}) → Future<List<String>>: Lists all internal files inside the app's internal memory
pick({FileTypeCross type = FileTypeCross.any, String fileExtension = ''}) → Future<FilePickerCross>: Deprecated. Use importFromStorage instead
quota() → Future<FileQuotaCross>: returns the maximally available storage space
save({FileTypeCross type = FileTypeCross.any, String fileExtension = ''}) → Future<FilePickerCross>: Deprecated. Use saveToPath or exportToStorage instead.
