You can use file_picker package instead. Moreover, you may need to use the path_provider package along with the file_picker package. Complete documentation and examples can be found on the pub pages of the mentioned packages.
Here are some code samples:
To pick a single file:
FilePickerResult? result = await FilePicker.platform.pickFiles();
if (result != null) {
File file = File(result.files.single.path);
} else {
// User canceled the picker
}
To pick multiple files:
FilePickerResult? result = await FilePicker.platform.pickFiles(allowMultiple: true);
if (result != null) {
List<File> files = result.paths.map((path) => File(path)).toList();
} else {
// User canceled the picker
}
To pick multiple files with Extensions filters:
FilePickerResult? result = await FilePicker.platform.pickFiles(
type: FileType.custom,
allowedExtensions: ['jpg', 'pdf', 'doc'],
);
To pick a directory:
String? selectedDirectory = await FilePicker.platform.getDirectoryPath();
if (selectedDirectory == null) {
// User canceled the picker
}
The usage for path_provider package:
Directory tempDir = await getTemporaryDirectory();
String tempPath = tempDir.path;
Directory appDocDir = await getApplicationDocumentsDirectory();
String appDocPath = appDocDir.path;
