# Barcode Scanner
|
|
|
|
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
|
|
|
|
### Features
|
|
- [x] Scan 2D barcodes
|
|
- [x] Scan QR codes
|
|
- [x] Control the flash while scanning
|
|
- [x] Permission handling
|
|
|
|
## 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" />`
|
|
|
|
* 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:
|
|
```groovy
|
|
buildscript {
|
|
ext.kotlin_version = '1.3.61'
|
|
// ...
|
|
dependencies {
|
|
// ...
|
|
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
|
|
}
|
|
}
|
|
// ...
|
|
```
|
|
|
|
Edit your app-level build.gradle file to look like this:
|
|
|
|
```groovy
|
|
apply plugin: 'kotlin-android'
|
|
// ...
|
|
dependencies {
|
|
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Now you can depend on the barcode_scan plugin in your pubspec.yaml file:
|
|
|
|
```yaml
|
|
dependencies:
|
|
# ...
|
|
barcode_scan: any
|
|
```
|
|
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
|
|
|
|
```xml
|
|
<dict>
|
|
<!-- ... -->
|
|
<key>NSCameraUsageDescription</key>
|
|
<string>Camera permission is required for barcode scanning.</string>
|
|
<!-- ... -->
|
|
</dict>
|
|
```
|
|
|
|
|
|
## Common problems
|
|
### Android "Could not find org.jetbrains.kotlin:kotlin-stdlib-jre..."
|
|
Change `org.jetbrains.kotlin:kotlin-stdlib-jre` to `org.jetbrains.kotlin:kotlin-stdlib-jdk`
