A linter runs for the Dart code and Objective-C/Swift code in the flutter/plugins and flutter/packages repos.

This issue tracks enabling it for Java and Kotlin.

We should be able to just use the command provided by gradle:
See https://developer.android.com/studio/write/lint

gradlew lint
./gradlew lint

I would imagine we would initially need a config file to exclude plugins and fix the lint warnings incrementally.
