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 = '1.3.21'
...
dependencies {
...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
...
Edit your app-level build.gradle file to look like this:
apply plugin: 'kotlin-android'
...
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
...
}
Now you can depend on the barcode_scan plugin in your pubspec.yaml file:
dependencies:
...
barcode_scan: any
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>
