[![pub package](https://img.shields.io/pub/v/flutter_barcode_scanner.svg)](https://pub.dartlang.org/packages/flutter_barcode_scanner)

![Demo gif](https://github.com/AmolGangadhare/MyProfileRepo/blob/master/flutter_barcode_scanning_demo.gif "Demo")

## Try example

Just clone or download the repository, open the project in `Android Studio/ VS Code`, open `pubspec.yaml` and click on `Packages get`.

Connect device and hit `run`. 

To run on iPhone you need to run from Xcode first time and just make `pod install` in `example/ios` then run from Xcode.

## Getting Started 

Follow the steps for Android and iOS

PLEASE FOLLOW **iOS** STEPS CAREFULLY

### Android

:zap:  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`. 

```

NSCameraUsageDescription

Camera permission is required for barcode scanning.

```

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

```  

dependencies:

  ...

  flutter_barcode_scanner: ^2.0.0

```

### 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

         });

```
