## Reborned🎉

Original [barcode_scan](https://pub.dev/packages/barcode_scan) was discontinued, so [barcode_scan2](https://pub.dev/packages/barcode_scan2) was borned with sound null safety support🎉

# barcode_scan2

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_scan2: 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>
```

### iOS 26+ Compatibility

This fork includes a fix for the 10-15 second delay when dismissing the scanner on iOS 26+. The fix is built-in - no additional configuration required.

## Usage

```dart
import 'package:barcode_scan2/barcode_scan2.dart';

void main() async {
  var result = await BarcodeScanner.scan();

print(result.type); // The result type (barcode, cancelled, failed)
  print(result.rawContent); // The barcode content
  print(result.format); // The barcode format (as enum)
  print(result.formatNote); // If a unknown format was scanned this field contains a note
}
```

## Advanced usage
You can pass options to the scan method:

```dart
import 'package:barcode_scan2/barcode_scan2.dart';

void main() async {

var options = ScanOptions(
    // set the options
  );

var result = await BarcodeScanner.scan(options: options);

// ...
}
```

### Supported options

## Development setup

###  Setup protobuf

Mac:

```bash
$ brew install protobuf
$ brew install swift-protobuf
```

Windows / Linux: https://github.com/protocolbuffers/protobuf#protocol-compiler-installation

Activate the protobuf dart plugin:

```bash
$ flutter pub global activate protoc_plugin
```

Install the`Protobuf Support` plugin for IDEA / Android Studio or `vscode-proto3` for VS Code

If you changed the protos.proto you've to execute the ./generate_proto.sh to update the dart / swift sources

## 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`
