FileSystem Picker

FileSystem file or folder picker dialog.

Allows the user to browse the file system and pick a folder or file.

Getting Started

In your flutter project add the dependency:

dependencies:
  ...
  filesystem_picker: ^1.0.3

Import package:

import 'package:filesystem_picker/filesystem_picker.dart';

Usage

To open the dialog, use the asynchronous FilesystemPicker.open method. The method returns the path to the selected folder or file as a string. The method takes the following parameters:

• context - widget tree context, required parameter;
• rootDirectory - the root path to view the filesystem, required parameter;
• rootName - specifies the name of the filesystem view root in breadcrumbs, by default "Storage";
• fsType - specifies the type of filesystem view (folder and files, folder only or files only), by default FilesystemType.all;
• pickText - specifies the text for the folder selection button (only for fsType = FilesystemType.folder);
• permissionText - specifies the text of the message that there is no permission to access the storage, by default: "Access to the storage was not granted.";
• title - specifies the text of the dialog title;
• folderIconColor - specifies the folder icon color;
• allowedExtensions - specifies a list of file extensions that will be displayed for selection, if empty - files with any extension are displayed. Example: ['.jpg', '.jpeg'];
• fileTileSelectMode - specifies the mode for selecting the file item (checkmark on the right or whole tile), by default: checkmark;
• requestPermission - specifies the callback to request storage permission, callers can use e.g. permission_handler.

Android permissions

To access the filesystem in Android, you must specify access permissions in the AndroidManifest.xml file, for example:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

  title: 'Save to folder',

  folderIconColor: Colors.teal,
);
