## Getting Started
|
|
|
|
### Android
|
|
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](https://kotlinlang.org/docs/tutorials/kotlin-android.html#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.
|
|
|
|
### iOS
|
|
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>
