I'd probably start simpler. I'd just start with either cbracken or matan's rules and see if I could get some basic Flutter projects building nicely with Bazel. Then I'd look to see how it would make sense to integrate with Flutter tools. I think there are still open questions as to what kinds of projects would want to use bazel. And if they do use bazel, what do they do for all the other services flutter_tools currently provides (like running on a device)? Inside Google they have different (bazel-specific) implementations for "run this app on an android device" so they don't use the `flutter` tool internally I don't think. I do think some of the internal bazel rules might call into `flutter` though? I'm not sure. Those are all question's I'd explore after having some working examples that I could stare at and decide if I liked the DX of them before proceeding further.
