The plugin qrscan uses a deprecated version of the Android embedding.

[viniciusddrft]

when I'm going to use the plugin I get this msg.

To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Hi, I get the same error!

Is this plugin abandoned? There is no update to plugin. Did you guys find any other solutions?

place
tools:replace="android:icon"

The android studio IDE suggested me to do that.

When I use drawable/ic_launcher.png
Instead of mipmap/ic_launcher.png

The IDE throws an error.

Here is my AndroidMenifest.xml file

Adding

tools:replace="android:icon"

this line inside tag fix this issue. Thank you!
