Access scanned preview
First of all, thanks for this amazing scanner, it works really fast.
However, after a barcode is scanned, I need to access the preview image, to pass it as a background for another screen/page.
I tried copying the _buildPreview
method into my project, and use it with the CameraController
as follows
var background = _buildPreview(
CameraController.instance.state.previewConfig!);
However, when compiling the project, I get the following error
Error: Member not found: 'instance'.
lib/…/scanner/scanner_widget.dart:112
CameraController.instance.state.previewConfig!);
Any help will be greatly appreciated
Update. This happens in version 2.0.0-dev.2
, did a downgrade to 1.1.4
and now I can get access to CameraController.instance
Hey, sorry for leaving you so long.
You are right, v2 does not use CameraController.instance
anymore. Instead you can just call CameraController()
to get an instance of the controller. Behind the scenes it behaves just like a singleton.
Is your issue solved or do you have suggestion for new features in v2?
