Getting Started

Follow the steps for Android and iOS

PLEASE FOLLOW iOS STEPS CAREFULLY

Android

⚡ Don't worry, you don't need to do anything.

iOS - Requires Swift support

Deployment target : 12

1. Fresh start:

1. Create a new flutter project. Please check for Include swift support for iOS code.
2. After creating new flutter project open /ios project in Xcode and set minimum deployment target to 12 and set Swift version to 5.
3. After setting up the deployment target and swift version, close the Xcode then run pod install in /ios in flutter project.

You have done with basic configuration now proceed to section How to use.

2. Adding to existing flutter app:

If your existing ios code is Swift then you just need to do following.

1. Set minimum deployment target to 12 and set Swift version to 5.
2. Close the Xcode and run pod install in /ios in flutter project.
3. Now proceed to section How to use.

If your existing ios code is Objective-C then you need to do following.

1. Create a new flutter project with same name at different location (Don't forget to check Include swift support for iOS code while creating)
2. Just copy newly created /ios folder from project and replace with existing /ios.
3. Open ios project in Xcode and set minimum deployment target to 12 and set Swift version to 5.
4. Run pod install in /ios

Note: If you did any changes in ios part before, you might need to make these configuration again

How to use ?

To use on iOS, you will need to add the camera usage description. To do that open the Xcode and add camera usage description in Info.plist.

<key>NSCameraUsageDescription</key>
<string>Camera permission is required for barcode scanning.</string>

After making the changes in Android ans iOS add flutter_barcode_scanner to pubspec.yaml

dependencies:
  ...
  flutter_barcode_scanner: ^1.0.4

One time scan

1. You need to import the package first.

import 'package:flutter_barcode_scanner/flutter_barcode_scanner.dart';

2. Then use the scanBarcode method to access barcode scanning.

String barcodeScanRes = await FlutterBarcodeScanner.scanBarcode(
                                                    COLOR_CODE, 
                                                    CANCEL_BUTTON_TEXT, 
                                                    isShowFlashIcon, 
                                                    scanMode);

Here in scanBarcode,

COLOR_CODE is hex-color which is the color of line in barcode overlay you can pass color of your choice,

CANCEL_BUTTON_TEXT is a text of cancel button on screen you can pass text of your choice and language,

isShowFlashIcon is bool value used to show or hide the flash icon,

scanMode is a enum in which user can pass any of { QR, BARCODE, DEFAULT }, if nothing is passed it will consider a default value which will be QR. It shows the graphics overlay like for barcode and QR.

NOTE: Currently, scanMode is just to show the graphics overlay for barcode and QR. Any of this mode selected will scan both QR and barcode.

Continuous scan

• If you need to scan barcodes continuously without closing camera use FlutterBarcodeScanner.getBarcodeStreamReceiver params will be same like FlutterBarcodeScanner.scanBarcode e.g.

FlutterBarcodeScanner.getBarcodeStreamReceiver("#ff6666", "Cancel", false, ScanMode.DEFAULT)
         .listen((barcode) { 
         /// barcode to be used
         });
