app_installer_plus

✨ New Features:

• Auto-Cleanup on Error: Added the deleteOnError parameter to downloadAndInstallApk. When set to true, the package will automatically delete incomplete APK files if the download fails due to a network or server error.
• Smart Cancellation: Added the deletePartialDownload parameter to cancelDownload. This gives developers explicit control to permanently delete the partial file when a user cancels an active download.

🛡️ Stability & Core Improvements:

• Concurrency Lock: Added bulletproof protection against concurrent downloads. Attempting to start a download while one is already active will now safely throw a DownloadErrorType.alreadyRunning exception instead of corrupting the file state.
• Storage Safety: Fixed an asynchronous race condition to guarantee orphaned or junk files are never left behind on the user's device after cancellations or unexpected HTTP status codes.
• Complete Documentation: Added comprehensive, pub.dev-compliant Dartdoc comments to all public classes, methods, and parameters for improved IDE Intellisense and perfect package scoring.

✨ New Features:

• Cancel Download: Added a new method to cancel an ongoing download request.
• Granular Progress Metrics: Added new callback parameters to downloadAndInstallApk for detailed UI updates:
  • onTimeLeft: Returns the estimated time remaining.
  • onSpeed: Returns the current download speed.
  • onTotalSize: Returns the total size of the file.
  • onDownloadedSize: Returns the currently downloaded file size.

⚠️ Deprecations & Updates:

• onError is Deprecated: You can still use the onError callback for now, and it will function without any issues. However, it is highly recommended to wrap your method call in a try-catch block to catch the new FileDownloadException instead.
• Future Removal: Catching the exception is the better approach for handling custom error messages, and the onError callback will be completely removed in future versions.

• Added GitHub repository link.

• Initial release of app_installer_plus.
• Support for downloading APK files from a direct URL.
• Progress tracking using onProgress callback.
• Secure APK installation using Android FileProvider.
• Example app demonstrating usage.
