Since these tasks aren't being passed either of the include/exclude flags, they will all run twice: once on the 34 shards and once on the 33 shards, even though there's no difference.

We should either pass the flags to everything, to keep all the tasks for a given plugin together, and running only in one place, or we should remove these two tasks from the 33 version, so all builds and lints run on the 34 shards.

I would vote for the former, for consistency, but either should work.

You'll need to add matching stable shards, or we'll lose coverage on stable since they are running the same scripts. That can be done in the same prequel PR.

This PR is quickly becoming outdated and I have been doing some experimental changes to fix the path provider flake (such as https://ci.chromium.org/ui/p/flutter/builders/try/Linux_android%20android_platform_tests_shard_4%20master/2375/overview). Will fix path provider (#5098) and then open a PR for landing this change.
