Explanation of how the Dart VM makes our code work from Vyacheslav Egorov's blog.

This article explains the internal structure of the Dart VM:

👉🏻 Isolates and threads
👉🏻 Transformation into Abstract Syntax Tree, IL, and machine code
👉🏻 Common front-end
👉🏻 JIT/AOT compilation and optimizations
👉🏻 And much more

All of this is accompanied by clear diagrams and links to code from the SDK repository.

How to create a PDF viewer tool using Flutter?

The folks at Flutter Bounty Hunters discuss the process of working on this, starting with the exploration of paid/free packages and ending with their own solution with jaw-dropping optimizations.

The presentation includes a lot of visual representation of the problems and solutions encountered along the way.

An article about how "built-in" data types in Dart work "under the hood" by Igor Molchanov

The author dives deep into the language and, using examples from the SDK code, explains how Dart makes it all work across so many platforms.

The comparison between Flutter and React Native is a well-worn and often contentious topic, but this article attracts me with its thoughtful approach and very specific conclusions.

The author compares performance using three case studies:

👉🏻 Scrolling a ListView with 1000 items
👉🏻 A large number of image animations
👉🏻 A large number of Lottie animations

Each case is accompanied by graphs of various metrics (FPS, memory, CPU load, etc.) and a denoscription of what was measured and on which platform.

We have unfairly overlooked the implementation of the data class by Felix Angelov.

This package implements, using macros:

👉🏻 A constant constructor
👉🏻 A copyWith method
👉🏻 A toString method
👉🏻 Type equality

Currently, macros are available under the experiment flag and do not guarantee stable performance, but it's still worth playing around with the package.

It will be interesting to see the 'arms race' between Freezed and this package.

Useful information for those who work with rather old versions of SDK. Starting with the release of Dart 3.6, support for versions older than 3.0 will be discontinued, so tools may continue to work with these versions, but there will be no official support or fix of problems with these versions.

An interesting package that allows you to "protect" your application under certain circumstances. For example, when the app goes into the background, a screenshot cannot be taken without the user's knowledge.

Telegram has similar functionality in secret chats.

The package also allows you to respond to events related to "locking" and configure some aspects.
