ios: trying to save shared image closes app without error

[esskar]

I am trying to save the image that i am sharing on iOS. The app crashes without notification/error

void _onSharePressed() async {
    try {
      final boundary =
          _qrCodeKey.currentContext.findRenderObject() as RenderRepaintBoundary;
      final image = await boundary.toImage(pixelRatio: 3);
      final byteData = await image.toByteData(format: ImageByteFormat.png);
      await WcFlutterShare.share(
          sharePopupTitle: 'share',
          subject: 'This is subject',
          text: 'This is text',
          fileName: 'test.png',
          mimeType: 'image/png',
          bytesOfFile: byteData.buffer.asUint8List());
    } catch (e) {
      print('error: $e');
    }
  }

Choosing to send the image by email, instagram, whatsapp works without problems. Saving to files works as well. Only save image crashes.

iPhone 8, ios 13.4.1

Have you set the required field in info.plist?

[aarajput]

@akshatjagga !! What fields ?

[imdangle]

@aarajput @esskar you should declare 2 fields in Info.plist to grant permission to access ios's library. It's only happend when build app for ios >= 10 or 11.

<key>NSPhotoLibraryAddUsageDescription</key>
<string>Message</string>    
<key>NSPhotoLibraryUsageDescription</key>   
<string>Message</string>
