A highly customizable Flutter package for integrating a barcode scanner into your applications.

Flexible Barcode Scanner

A highly customizable and efficient barcode scanner library built with Flutter. This package uses the camera package and Google ML Kit Barcode Scanning capabilities to provide real-time barcode scanning with additional features like overlay animation and custom configurations.

• Customizable Camera View: Modify the camera preview with custom overlays and actions.
• Barcode Detection: Supports various barcode formats using Google ML Kit.
• Format Selection: Scan only specific barcode formats (QR codes, EAN-13, Code 128, etc.) or all formats. Uses built-in FlexibleBarcodeFormat enum - no extra imports needed!
• Animated Overlay: Includes a sleek animation for scanning feedback.
• Camera Switch: Easily switch between front and rear cameras.
• Flashlight Toggle: Enable or disable flashlight for better scanning in low light.
• Platform Compatibility: Fully supports both Android and iOS platforms.
