How to effectively serialize data in Dart & Flutter?
There is a very sophisticated way:
Dart has a built-in package called "dart:convert" that includes codecs for UTF8, json, base64, ASCII, and other formats that you may already be using.

Rust is an amazing language for FFI in Dart
All you need to do is define the extern C function, run cbindgen to generate a C header file, and then run ffigen, which generates safe Dart bindings.
Here is how I implemented upscale using Rust's "image" crate, which is 50x faster than dart's "image" package.
I think this is not the best solution and if you know how to improve it, it would be greatly appreciated! :)

When updating dependencies in a Pub Workspace, use "dart pub upgrade," which automatically resolves to the correct version and updates it in every package.

I created a Shimmer animation in Flutter in 100 lines without libraries.
It is performant and minimizes rebuilds, based on a CustomPaint, a LinearGradient, and a Transform.

Don't use SVGs for Icons in Flutter. There are better and more performant ways.
Rendering SVG requires several time-consuming operations: reading from memory, parsing the SVG to a binary format, parsing the binary format to Dart structures, and only then rendering.
Instead, opt for icon fonts, similar to the Icons class in Flutter. A Flutter engine processes all the fonts during startup and makes them available throughout the whole app lifecycle. The performance of rendering an icon font is the same as rendering text.
