deminearchiver/dart-flutter-packages ? reverse-engineered prompt

Build me a Dart and Flutter monorepo that groups a bunch of reusable packages together, like shared lint rules, color utilities for Material style themes, icon font helpers, layout tools, and a few Flutter plugins that use native code through FFI.

I want the repo set up so each package can be developed and published on its own, but still shares the same workspace rules and code quality setup. Please include a clean README, consistent analysis settings, and a sensible package structure for things like icons, framework pieces, and native integrations. Make it easy to add more packages later, and make the packages feel like they belong together.

If anything needs current package or tooling details, look up the latest docs online first.
