iOS/Android: once permissions are denied camera will flash when the user tries to scan

[natalieeeflores]

The app will briefly open the camera when a user denies camera permissions. I am able to reproduce this behavior with the example app in this repo.

Steps to reproduce:

1. Press scan button
2. Deny camera permissions
3. Press scan button again

barcode_scan version: 2.0.1

Devices reproduced on:
iPhone 10R, iOS 13.3.1
Samsung Galaxy S9, Android 10

Please check if the fix in PR #186 works for you🙂

I've been having some issues testing the fix on android. I keep getting build failures when I try to run my project: Execution failed for task ':barcode_scan:compileDebugKotlin'.
However, I have been able to run the project on an iOS device and can confirm that the bug is still reproducible

Please run flutter clean and then open the Android Module directly (Android Studio -> Right click on your project root -> Flutter -> Open Android Module in Android Studio)

Unfortunately, my project still isn't running on android after following those steps. Here's the output from android studio:
/.pub-cache/git/flutter_barcode_reader-ea67104d0024de29a73602a8c35c279900db20b7/android/src/main/kotlin/de/mintware/barcode_scan/BarcodeScannerActivity.kt: (33, 30): Unresolved reference: it

I'm running it on a new project that I've created, I followed the instructions in the readme, and copy-pasted the code in example/lib/main.dart. Thanks for your help in all this!

In 2.0.2 the problem was resolved: https://pub.dev/packages/barcode_scan/versions/2.0.2
