Ultra-fast, highly efficient download engine written in pure dart

:gear: About Brisk Engine

Brisk-Engine is the download engine that powers Brisk Download Manager now available as a separate library. It is written in pure dart and can be used in all devices without platform-specific dependencies.

:rocket: Features

• Dynamic Connection Spawn: Downloads begin with a single connection, with more connections dynamically added on the fly.
• Dynamic Connection Reuse: Completed connections are reassigned to assist other active connections, maintaining the maximum number of concurrent connections to maintaining the highest possible download speed.
• Automatic connection reset: Hanging connections will be reset automatically.

Example Usage

/// Build the download item either by using this method or manually building it
/// using HttpDownloadEngine.requestFileInfo(url). Note that buildDownloadItem(url)
/// automatically uses an isolate to request for file information while requestFileInfo
/// does so in the same isolate.
final downloadItem = await HttpDownloadEngine.buildDownloadItem(url);

/// Start the engine
DownloadEngine.start(
  downloadItem,
  settings,
  onButtonAvailability: (message) {
  /// Handle button availability. A download should only be paused or resumed
  /// when the buttons are available as notified in this method. Otherwise, it could
  /// lead to a corrupted file.
  },
  onDownloadProgress: (message) {
  /// Updates on the download progress will be notified here
  },
);

/// You can use the UID which is set on the downloadItem to pause/resume the download

/// Pause the download
DownloadEngine.pause(downloadItem.uid);

/// Resume the download
DownloadEngine.resume(downloadItem.uid);
