A package that allows you to use the native file explorer to pick single or multiple files, with extensions filtering support.

- Supports multiple platforms (Mobile, Web, Desktop and Flutter GO)
- Pick files using custom format filtering — you can provide a list of file extensions (pdf, svg, zip, etc.)
- Pick files from cloud files (GDrive, Dropbox, iCloud)
- Single or multiple file picks
- Different default type filtering (media, image, video, audio or any)
- Picking directories
- Load file data immediately into memory (
Uint8List
) if needed; - Open a save-file / save-as dialog (a dialog that lets the user specify the drive, directory, and name of a file to save)

Usage #
Quick simple usage example:
Single file
FilePickerResult? result = await FilePicker.platform.pickFiles();
if (result != null) {
File file = File(result.files.single.path);
} else {
// User canceled the picker
}
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
}
Multiple files with extension filter
FilePickerResult? result = await FilePicker.platform.pickFiles(
type: FileType.custom,
allowedExtensions: ['jpg', 'pdf', 'doc'],
);
Pick a directory
String? selectedDirectory = await FilePicker.platform.getDirectoryPath();
if (selectedDirectory == null) {
// User canceled the picker
}
Save-file / save-as dialog
String? outputFile = await FilePicker.platform.saveFile(
dialogTitle: 'Please select an output file:',
fileName: 'output-file.pdf',
);
if (outputFile == null) {
// User canceled the picker
}
Load result and file details #
FilePickerResult? result = await FilePicker.platform.pickFiles();
if (result != null) {
PlatformFile file = result.files.first;
print(file.name);
print(file.bytes);
print(file.size);
print(file.extension);
print(file.path);
} else {
// User canceled the picker
}
Pick and upload a file to Firebase Storage with Flutter Web
FilePickerResult? result = await FilePicker.platform.pickFiles();
if (result != null) {
Uint8List fileBytes = result.files.first.bytes;
String fileName = result.files.first.name;
// Upload file
await FirebaseStorage.instance.ref('uploads/$fileName').putData(fileBytes);
}
