Small misuses that do not directly break functionality can be no less dangerous than regular bugs. And sometimes even more dangerous. A bug is obvious: it is easy to notice and fix it. But such “trifles” remain in the shadows for a long time, but over time they accumulate and can seriously reduce application performance.

In his article, Majid Hajian gives examples of such misuses in working with asynchronous operations.

A big move from Flutter, which has been desired for a long time in the community, is a reality now. The process of separating the design libraries from the framework has started.

📌 The design document and tracking project are available at the links.

Meet the new Dart 3.9.0 version, which includes:

👉 Dart 3.9 assumes null safety when computing type promotion, reachability, and definite assignment. This makes these features produce more accurate results for modern Dart programs
👉 Support for tag-pattern in git tags for pubspec dependencies
👉 Outstanding async code now checks and cancels itself after a hot restart if it was started in a different generation of the application before the restart

A rather "ancient" article, but cool enough to still talk about after all these years 😎

The author shares their experience creating an app that opens their garage as they approach it 😁

The app executes a Dart callback in the background on the platform side and uses the device's geofencing API.

The article is packed with technical details, accompanied by links to the repository.

The new episode of Package of the Week is dedicated to a Storybook equivalent for widgets, aptly named Widgetbook 😄

This package allows you to generate code to create your own "catalog" of widgets for demonstration and testing purposes.

Recently, a new concept called Native Assets has appeared in the language, but what are they and why are they needed?

The Dart team answers these and some other questions. This article describes key concepts in sufficient detail to provide a basic understanding of why Native Assets are needed, what Build Hooks are, and how to make them work together.

The latest episode of Observable Flutter is dedicated to working with AI, but this time it looks like a genuinely good way to eliminate boilerplate code related to implementing an app's design system.

As a guest, Muhammad Hamza will demonstrate how, using Figma MCP, much of the implementation of things like theming, assets, typography, and so on can be delegated to a neural network based on Figma mockups.

Recently, my team and I have been working extensively on creating an SDK that integrates into native applications and operates under a strict protocol. We used Pigeon, but faced limitations: the specifics required us to develop custom solutions, and thus Golubets was born.

Everything we’ve managed to achieve and build is consolidated within this fork.

Currently, Golubets supports (Swift and Kotlin only):
👉 Default parameters in classes
👉 Suspend/Async functions for Swift and Kotlin
👉 Generics in classes
👉 Nested sealed classes in Kotlin
👉 Enum sealed classes in Swift
👉 Fixed some bugs

The fork is regularly synchronized with its "parent" but is already evolving with its own unique features.

In the plans:
👉 Add existing functionality for other languages
👉 Continue fixing existing bugs
👉 Implement features that have been untouched for years

We welcome everyone! Plus, we don’t hand out silent bans 😁
