A flutter plugin for scanning 2D barcodes and QR codes.

This provides a simple wrapper for two commonly used iOS and Android libraries:

iOS: https://github.com/mikebuss/MTBBarcodeScanner

Android: https://github.com/dm77/barcodescanner

• Scan 2D barcodes
• Scan QR codes
• Control the flash while scanning
• Permission handling
• Support multiple barcode libraries

For Android, you must do the following before you can use the plugin:

• Add the camera permission to your AndroidManifest.xml

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

• Add the BarcodeScanner activity to your AndroidManifest.xml. Do NOT modify the name.

  <activity android:name="com.apptreesoftware.barcodescan.BarcodeScannerActivity"/>

• This plugin is written in Kotlin. Therefore, you need to add Kotlin support to your project. See installing the Kotlin plugin.

Edit your project-level build.gradle file to look like this:

buildscript {
    ext.kotlin_version = '1.2.31'
    ...
    dependencies {
        ...
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
...

Edit your app-level build.gradle file to look like this:

apply plugin: 'kotlin-android'
...
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    ...
}

Now you can depend on the barcode_scan plugin in your pubspec.yaml file:

dependencies:
  ...
  barcode_scan: ^0.0.3

Click "Packages get" in Android Studio or run flutter packages get in your project folder.

To use on iOS, you must add the the camera usage description to your Info.plist

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