freezed VS plugins

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.

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.

The official site does show what you can use it for but to explain a bit more, it helps you work faster.

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.

Read more on what you can do with Freezed.

We use freezed for our models, and then use withConverter in the firestore SDK to easily translate between firestore and our models... however we run into issues with concurrent updates to documents.

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:

Data class: freezed

I've recently been exploring a codebase which is heavily using Freezed with Bloc. The resulting code base is almost an entirely different language altogether, and comes with almost triple the files of a non-freezed codebase.

(This new version will be endorsed by google_sign_in: ^6.0.0, once this PR lands: https://github.com/flutter/plugins/pull/7191, probably next week. This was made a major version change so people can test and update at their own pace.)

Looking at the web version of the video player package which doesn't use textures but VideoElement DOM nodes, I'd guess that textures aren't supported.

It's not 100% true that Flutter doesn't offer any first party native features. These plugins are maintained by the Flutter team: https://github.com/flutter/plugins/tree/main/packages

Here's an example: https://github.com/flutter/plugins. As you can see, that repo has no "issues" tab. And it mentions that issues should be created on the Flutter repo itself

There's work in progress to create a new camera plugin using CameraX: https://github.com/flutter/plugins/pull/6158

The plugins is missing Issues tab currently. It's hard for developers who need to raise or find issues on packages.
