flutter/packages

This repository is a monorepo for Flutter plugins and supporting packages, providing cross-platform implementations for common device features such as camera access, file selection, video playback, and web views. It also includes utility packages for UI components, routing, and testing infrastructure. The codebase has been modernized by migrating native Android and iOS code to Kotlin and Swift, and standardizing platform communication using the Pigeon code-generation tool.

2023–2026 · Plugin modernization and UI decoupling

This period focused on modernizing native plugin implementations by migrating to Pigeon for type-safe platform channels and converting Android example apps to Kotlin. Simultaneously, the codebase expanded its modular architecture by decoupling Cupertino and Material UI widgets into standalone packages, while significantly increasing test coverage across the ecosystem.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 5 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 4e3f83d37f — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
