# Barcode Scanner
A flutter plugin for scanning 2D barcodes and QR codes.
@ -13,7 +18,6 @@ Android: https://github.com/dm77/barcodescanner
- [x] Scan QR codes
- [x] Control the flash while scanning
- [x] Permission handling
- [ ] Support multiple barcode libraries
## Getting Started
@ -24,44 +28,55 @@ For Android, you must do the following before you can use the plugin:
`<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 = '1.3.21'
...
dependencies {
...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
...
```groovy
buildscript {
ext.kotlin_version = '1.3.61'
// ...
dependencies {
// ...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
// ...
```
Edit your app-level build.gradle file to look like this:
apply plugin: 'kotlin-android'
...
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
...
}
```groovy
apply plugin: 'kotlin-android'
// ...
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
// ...
}
```
Now you can depend on the barcode_scan plugin in your pubspec.yaml file:
dependencies:
...
barcode_scan: any
```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`

- `com.yourcompany.barcodescan`
- `com.apptreesoftware.barcode_scan`
With: `de.mintware.barcode_scan`
Detailed changes:
Android:
Kotlin Package: `com.apptreesoftware.barcodescan` -> `de.mintware.barcode_scan`
Manifest-Package: `com.yourcompany.barcodescan` -> `de.mintware.barcodescan`
Activity: `com.apptreesoftware.barcodescan.BarcodeScannerActivity` -> `de.mintware.barcode_scan.BarcodeScannerActivity`
iOS:
Bundle ID: `com.apptreesoftware.barcode.plugin.example` -> `de.mintware.barcode_scan.plugin.example`
Flutter:
Method channel: `com.apptreesoftware.barcode_scan` -> `de.mintware.barcode_scan`
pubspec.yaml:
- homepage updated
- deprecated author entry removed
- comments removed
- flutter.plugin.androidPackage: `com.apptreesoftware.barcode_scan` -> `de.mintware.barcode_scan`
