If you are here it means that you are facing a frustrating exception regarding Android licenses in Flutter.
More specifically the exception occurs when you try to run the following command:
$ flutter doctor --android-licensesand the output is something like this:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)

... 5 moreThe easiest fix I found is to install the Android SDK Command-line Tools.
In Android Studio open
File > Settings > Appearance & Behavior > System Settings > Android SDK > SDK Tools
then tick the corresponding element, install and restart Android Studio and everything shoul work like a charm.
