File Picker

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

Currently supported features

• Uses OS default native pickers
• 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)

If you have any feature that you want to see in this package, please feel free to issue a suggestion. 🎉

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);
}
