Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The download package provides a cross-platform file downloader for Dart and Flutter applications, enabling seamless file downloads across Android, iOS, Web, macOS, Windows, and Linux. It offers a simple API to initiate downloads, monitor progress, and handle file storage with platform-specific optimizations. Designed for reliability and ease of use, it supports background downloads and integrates smoothly into apps requiring offline content or media retrieval.

Use cases

  • Downloading files from URLs in mobile apps
  • Fetching assets for offline use
  • Supporting background downloads on all platforms
  • Integrating with media or document management features
  • Enabling app updates via downloadable bundles

Key features

  • Cross-platform compatibility
  • Progress tracking during downloads
  • Background download support

Suitable for

  • Mobile and desktop Flutter apps
  • Apps needing offline content

  • Projects requiring reliable file retrieval
  • Developers seeking minimal setup for downloads

Considerations

  • Requires proper permissions on Android and iOS

Features

Supports these platforms:

  • Android
  • iOS
  • Linux
  • MacOS
  • Web
  • Windows

There are a few caveats about this package:

  • On the web it caches the contents in a Blob and eventually saves the file in browser's default location.
  • On desktop it saves the file in absolute or relative path.
  • On mobile it saves the file in absolute or relative path, but we should ask/ensure if the app has the required permissions.
  • On the web, not supported in IE or Edge (prior version 18), or in Safari (prior version 10.1).

Getting started
