Dart 3.3
There is the `sealed` class modifier which allows for exhaustive matching on possible types: https://dart.dev/language/class-modifiers#sealed
There's also a package called freezed which offers similar utility (you might already be familiar with this seeing as you mentioned pattern matching): https://pub.dev/packages/freezed
I recall there being a reason unions aren't generally implemented, though I'm not sure where I read it. It was to do with union types being unnecessarily complex for the compiler and the code they tend to produce, at no real benefit to the programmer or the resulting program. Go's lack of unions is essentially based around the same reasoning.

Fluvera is a Flutter SDUI package designed to simplify the process of building user interfaces (UIs) based on JSON server responses.
Interesting. May I ask how this differs from something like Freezed https://pub.dev/packages/freezed and its from/ToJson features ? I haven't used it yet, but I'm just curious about the concept and use of these sort of packages.

🎉 Introducing MODDDELS: A Powerful Package for Robust, Self-Validated Models in Flutter & Dart
One rather minor suggestion: it took me a while to understand exactly what the benefits were, but the example shown on this page of the docs summarized it well. I would suggest showing an example like that at the top of the main Readme and first page of the site, before or right after the motivation section, similar to how Freezed immediately shows its value proposition.

🚀 Building a Fullstack App with dart_frog and Flutter in a Monorepo - Part 2
Once the package has been created, we will install freezed for JSON serialization and value equality , as this library provides helpful tools for these tasks. We will use json_serializable for JSON serialization. To install freezed and freezed_annotation, open your terminal inside the models package and use the command:

Weezer's Lead Singer is still strong coding
What were your problems with it? I found it to be basically typescript, but without javascript's awful baggage and no union types, which is fixable with https://pub.dev/packages/freezed

We will now create a new file called build.yaml in the failures directory and add the following code. This will change the behaviour of the json_serializable so that it generates JSON keys in snake_case.

Source code generation in Flutter & Dart (Part 1): Reflection and code gen
Have developers annotate classes with @JsonSerializable. The annotated class must conform to a set of guidelines for the process to work correctly.
However, we cannot do this kind of JSON de-serialization in Flutter. Without reflection, we need to consider other approaches for these same tasks. For instance, the package json_serializable uses source code generation for decorating classes with methods to serialize and de-serialize JSON strings.

How to create a custom plugin in Flutter with Pigeon
We could work around having to introduce parsing logic by using a package such as json_serializable to parse data to and from JSON to save ourselves some time. However, you'd need to make sure the native platforms are returning the data in the exact format you are expecting, and vice versa. Otherwise the parsing will fail.
