Use case

In the build and release on android page,
https://flutter.dev/docs/deployment/android#step-1---configure-proguard

There are indications that we need additional proguard rules for firebase products.

In the firebase launch checklist,
https://firebase.google.com/support/guides/launch-checklist#authentication

We are told to configure proguard rules to work with auth. But clicking on the link (https://firebase.google.com/docs/auth/android/start/#proguard) produces nothing at all.

This is kind of confusing. And the warnings during minification/obfuscation of release build are also very scary as to the stability of the release builds.

Proposal

Readme of the official plugins should come with their release build instructions, that include precise guidance of if there are additional configuration like proguard needed, and exactly what those rules are, and should be updated if those rules change.
