Answer 1

For the Android license issue, what happens when you run flutter doctor --android-licenses on the command line? Hopefully, it'll run you through the steps to accept the licenses.

For the unsupported class issue, does running a Gradle clean solve the problem? To do this, you should be able to navigate to the projects android directory on the command line and run gradlew clean .
