To update Flutter in Playground, currently the following needs to be updated:

## Project files that declare minimal required versions as we desire, one per Flutter project:

## Generated project files with computed minimal versions given the package requirements, one per runnable Flutter app:

## Pinned versions for tools that work on our projects:

https://github.com/apache/beam/blob/d20d0b01c3c6bcde551420f36e13d794c930f1e2/playground/frontend/Dockerfile#L20

Need a single place to define the version instead.

## CI
