This plugin package is not much but only for saving files in Android, iOS, Web, Windows, MacOS and Linux. The package depends on path_provider for Android and iOS and basic html anchor for Web The main reason I built this plugin was to avoid using html only for downloading files. The plugin is pretty simple and saves the file in Downloads folder in Windows, MacOS, Linux and directly downloads the file in Web, in iOS, the file is Saved in Application Documents Directory, and in Android it is saved in the applications files directory Android/data/

Getting Started

The plugin itself is pretty easy to use. Just call the method saveFile() with respective arguments.

    await FileSaver.instance.saveFile(String name, Uint8List bytes, String ext, mimeType: MimeType);

This saveFile() method takes 3 Positional Arguments. String name which takes the name of the file, Uint8List bytes which will be your actual encoded file, String ext this will be your file extension. 1 Optional Named Argument Specifically for Web MimeType type which will be your file type, MimeType is also included in my Package, I've included types for Sheets, Presentation, Word, Plain Text, PDF, MP3, MP4 and many other common formats

or you can call saveAs() only available for android and iOS at the moment

    await FileSaver.instance.saveAs(String name, Uint8List bytes, String ext, MimeType);

All the parameters in this method is same as the saveFile() method, the only difference is all the parameters here are positional

Storage Permissions:

These Settings are optional for iOS, as in iOS the file will be saved in application documents directory but will not be visible in Files application, to make your file visible in iOS Files application, make the changes mentioned below.


Go to your project folder, ios/Runner/info.plist and Add these keys:



Or in XCode:

Open Your Project in XCode (Open XCode -> Open a project or file -> Your_Project_Folder/ios/Runner.xcworkspace) Open info.plist Add these rows:

iOS Xcode


Go to your project folder, macOS/Runner/DebugProfile.entitlements

For release you need to open 'YOUR_PROJECT_NAME'Profile.entitlements

and add the following key:



Or in XCode:

Open Your Project in XCode (Open XCode -> Open a project or file -> Your_Project_Folder/macos/Runner.xcworkspace) Open your entitlement file (DebugProfile.entitlements & 'YOUR_PROJECT_NAME'Profile.entitlements)

Add these rows: MacOS Xcode

And You're done
