Flutter Barcode Scanner SDK - Getting Started

Installation​

The Scanbot Barcode Scanner SDK Flutter Plugin is available as a Flutter Dart package barcode_scanner on pub.dev. You can simply add it as a dependency to your app.

Add the barcode_scanner plugin to your pubspec.yaml file as dependencies:

dependencies:
  barcode_scanner: ^3.6.0  # use the latest plugin version

Use the Flutter CLI (or your IDE) to fetch and install the packages:

$ flutter pub get

Android​

In the top-level android/build.gradle file:

  • Update Kotlin version to at least 1.3.61 or higher. Typically defined via ext.kotlin_version variable:

    ...
    buildscript {
        ext.kotlin_version = '1.3.61'
        ...
    }

In the app-level android/app/build.gradle file:

  • Add the following packagingOptions

      android {
          ...
          packagingOptions {
              pickFirst 'META-INF/atomicfu.kotlin_module'
              pickFirst 'META-INF/proguard/coroutines.pro'
              exclude 'META-INF/LICENSE.txt'
              exclude 'META-INF/NOTICE.txt'
              exclude 'META-INF/LICENSE'
              exclude 'META-INF/NOTICE'
          }
      }

In the android/app/src/main/AndroidManifest.xml file:

  • Add the CAMERA permission:
    <uses-permission android:name="android.permission.CAMERA" />

iOS​

For iOS you need to adjust the Podfile and install or update the Pods:

Make sure you have specified a global platform version in the ios/Podfile file, like:

platform :ios, '9.0'

Then run:

$ cd ios/
$ pod install

In your Info.plist file add the required NSCameraUsageDescription property:

NSCameraUsageDescription - "Privacy - Camera Usage Description". Describe why your app wants to access the camera.

Please note that without this property the app will crash on camera access!
