Hi Luke,
Request for QR flutter to add read capabilites, if its not too much trouble.
I'm sure you're busy with stuff but I'm having a rough time with what's available on pub.dartlang.org/flutter.
I've not been able to get any of these to work so far. All required a tweek of manifest.xml, build.gradle, app/build.gradle or pubspec.yaml, and that is just to make the given examples compile to an .apk. with gradle. It doesn't mean they have worked. Not a single one has activated the camera on my android phone.
I was going to write to the authors but then I realised that I would have to write to them all. I don't think I'm ready so start writing plugins so that leaves me seeking help elsewhere.
Various errors included (as i run these on Oreo 28 phone and 26-28 virtual devices):
'problems with minSDKVersion', having to set 'multiDexEnabled', etc.
qr_reader 0.1.3
https://pub.dartlang.org/packages/qr_reader#-readme-tab-
doesn't open|find camera.
qr_mobile_vision: ^0.0.7
'camera inactive' 'camera missing'
'I/flutter (19099): MissingPluginException(No implementation found for method start on channel com.github.rmtmckenzie/qr_mobile_vision)'
fast_qr_reader_view 0.1.2
https://pub.dartlang.org/packages/fast_qr_reader_view
'no camera found'. Scanning frame comes up as red box but no camera activated.
barcode_scan 0.0.4
https://pub.dartlang.org/packages/barcode_scan
no working
flutter_mobile_vision: ^0.1.1
'...refers, in an import, to the following library:
package:flutter_mobile_vision_example/barcode_detail.dart
That library is in a package that is not known. Maybe you forgot to mention it in your pubspec.yaml file?'
Sadly, or happily, the only plugin that I can get a camera even launching on is Camera. The example worked 'straight out of the box' , unlike all the above plugins, once I added 'path_provider' and 'video_player'.
camera 0.2.1
https://pub.dartlang.org/packages/camera
I think this is because it has 'flutter team' as part of the contributors along with at least 4 other programmers.
Although there are numerous applications of QR squares with the app i'm tinkering with now I'd like for flutter to be able to 'read and create' ethereum addresses with visuals and camera scan capabilities. Using qr_flutter I can create visual ethereum addrs easily
['0x' + 40 alphanumeric chars, something like 'final RegExp ethAddExp = new RegExp(r'0x[a-fA-F0-9]{40}');'].
Now I would also like for 2+ mobile devices to be easily able to exchange ethereum addresses with qr codes and camera access. Obviously, if I can get ethereum up and running it should be simple to add other blockchain coins with ease.
Anyway, just something for you to think about , Luke, if you wanted to make yourself useful! :-) If I end up releasing this app to the wide world then it would be in a month or two. Is that enough time for you?
Otherwise, let me know if you have any other temporary fixes or think I should take another look at one of these programmers and plugins, if possible.
Ciao,
