app keeps stopping

[SamirRana5]

After adding flutter_mobile_vision_2, when closing the app I get "app keeps stopping" message.

Did you update the androidmanifest.xml file?

Can I see the code you are using?

what's wrong?

For Android, you must do the following before you can use the plugin:

Add the camera permission to your AndroidManifest.xml

<uses-feature android:name="android.hardware.camera" />

<uses-permission android:name="android.permission.CAMERA" />

Add the Barcode activity to your AndroidManifest.xml (after other activity nodes)
