Installation

First, add qr_code_dart_scan as a dependency in your pubspec.yaml file.

iOS

iOS 10.0 of higher is needed to use the camera plugin. If compiling for any version lower than 10.0 make sure to check the iOS version before using the camera plugin. For example, using the device_info plugin.

Add two rows to the ios/Runner/Info.plist:

• one with the key Privacy - Camera Usage Description and a usage description.
• and one with the key Privacy - Microphone Usage Description and a usage description.

Or in text format add the key:

<key>NSCameraUsageDescription</key>
<string>Can I use the camera please?</string>
<key>NSMicrophoneUsageDescription</key>
<string>Can I use the mic please?</string>

Android

Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle file.

minSdkVersion 21

It's important to note that the MediaRecorder class is not working properly on emulators, as stated in the documentation: https://developer.android.com/reference/android/media/MediaRecorder. Specifically, when recording a video with sound enabled and trying to play it back, the duration won't be correct and you will only see the first frame.

Using

      body: QRCodeDartScanView(

          // do anything with result
