The Flutter plugin for iOS and Android to decoding QR codes.

First, add qr_code_tools as a dependency in your pubspec.yaml file.

Add one rows to the ios/Runner/Info.plist:

• one with the key Privacy - Photo Library Usage Description and a usage description.

Or in text format add the key:

<key>NSPhotoLibraryUsageDescription</key> <string>Can I use the photo library please?</string>

Nothing to do

import 'package:qr_code_tools/qr_code_tools.dart'; String _data; /// decode from local file Future decode(String file) async { String data = await QrCodeToolsPlugin.decodeFrom(file); setState(() { _data = data; }); }
