+## Supported platforms
+
+Flutter ZXing supports the following platforms:
+
+- Android (minimum API level 21)
+- iOS (minimum iOS 11.0)
+- MacOS (minimum osx 10.15) (beta)
+- Linux (beta)
+- Windows (beta)
+
+Note that flutter_zxing relies on the Dart FFI (Foreign Function Interface) feature, which is currently only available for the mobile and desktop platforms. As a result, the plugin is not currently supported on the web platform.
 
-- Scan barcode from camera stream, image path or url
-- Scan multiple barcodes from camera stream, image path or url
-- Create barcode from text
-- Return scanned barcode position points
-- Flashlight and pinch to zoom support
+In addition, flutter_zxing uses the camera plugin to access the device's camera for scanning barcodes. This plugin is only supported on mobile platforms, and is not available for desktop platforms. Therefore, some features of flutter_zxing, such as scanning barcodes using the camera, are not available on desktop platforms.
