File and directory picker for Windows that uses common dialog controls.

This package builds on top of the package:win32 and provides a high-level abstraction over native registry APIs. It eliminates the need to work directly with FFI, raw pointers, or low-level Win32 calls while preserving performance and correctness.

✨ Features

• 📂 Open a single file or multiple files simultaneously
• 💾 Save a file
• 📁 Select a directory
• 🔍 Filter by file type with friendly display names
• 📌 Add custom places to the dialog's navigation pane
• 🪟 Pin to the correct window — always opens as a modal in front of your app

🚀 Getting Started

Add the package to your pubspec.yaml:

dependencies:
  filepicker_windows: ^3.0.0

Then import it:

import 'package:filepicker_windows/filepicker_windows.dart';

⚡ Quick Example

Show a file open dialog:

import 'package:filepicker_windows/filepicker_windows.dart';

void main() {
  final picker = OpenFilePicker()
    ..filterSpecification = {
      'Word Document (*.doc)': '*.doc',
      'Web Page (*.htm; *.html)': '*.htm;*.html',
      'Text Document (*.txt)': '*.txt',
      'All Files': '*.*',
    }
    ..defaultFilterIndex = 0
    ..defaultExtension = 'doc'
    ..title = 'Select a document';

  final file = picker.getFile();
  if (file != null) {
    print('Selected file: ${file.path}');
  } else {
    print('No file selected.');
  }
}

More examples — including multi-file selection, save dialogs, directory picking, and custom places — are available in the example directory.

For a more advanced demonstration, see example/wallpaper/, a Flutter app that uses the picker to select an image and set it as the desktop wallpaper.
