Many layout options are available like: width, height, margin, padding, colors, etc.
To add a logo on top of a QrCode, use Flutter's composing abilities while increasing the error recovery density:
Stack(
alignment: Alignment.center,
children: [
BarcodeWidget(
barcode: Barcode.qrCode(
errorCorrectLevel: BarcodeQRCorrectionLevel.high,
),
data: 'https://pub.dev/packages/barcode_widget',
width: 200,
height: 200,
),
Container(
color: Colors.white,
width: 60,
height: 60,
child: const FlutterLogo(),
),
],
)
