4 years ago Try again with this PR that I just submitted: https://github.com/giandifra/arcore_flutter_plugin/pull/63
You can specify a specific commit and git repo in pubspec.yaml. If you want to use my fork, which also has this fix, you can do the following:
arcore_flutter_plugin:
git:
url: https://github.com/BrutalCoding/arcore_flutter_plugin.git
Im trying to use this plugin with: import 'package:qrscan/qrscan.dart' as scanner;
But when i run: String barcode = await scanner.scan();
The app crashes, while if i dont put: ArCoreView( onArCoreViewCreated: _onArCoreViewCreated, enableTapRecognizer: true, ) In my code then it works.
How can i solve this? thank you!
