dart_avif_decoder

AVIF decoding functionality for both native and Web WASM environments. This package is derived from the decoder component of flutter_avif, enhanced with Web support.

flutter_avif should be preferred. This is much narrower, and only has the decoder with a new Web implementation.

Full Notes

The situation resulting in this being the best situation is complex.

• flutter_avif is based on flutter_rust_bridge, which changed significantly in 2.x.x, enough that the flutter_avif has found it difficult to find time to update.
• Updating flutter_avif in place didn't work, as the author notes, it is a significant amount of work, and in my estimation, it may not be possible. There's not many docs on migrating from 1.x.x to 2.x.x, and those that exist recommend running a flutter_rust_bridge create . command, much like you'd run flutter create . on an existing project to add a new platform. However, flutter_rust_bridge create variant is challenging to understand in the context of an upgrade, it resulted in new demos and API replacing some of the existing ones, and others didn't seem to update.
• At that point, I tried creating a new flutter_rust_bridge project, and then porting the flutter_avif code into it. This worked on native, however, not on web. I have a feeling flutter_avif is set up to do custom initialization of the plugin to handle this situation, but it's not clear how to do that and support the new flutter_rust_bridge setup.
• At that point, I decided to prioritize the core feature in flutter_avif required for my use case, turning an AVIF into a dart:ui.Image. I wrote a web implementation that avoids using flutter_rust_bridge entirely and uses dart:web and dart:js_interop only. This is the package you see here.
