Nit: Maybe something more descriptive, like Vector Graphics Compiler - Build Hooks Example

Are there technical reasons for only supporting this on Linux? Ideally we'd at least support the desktop platforms so that the majority of our users can run this.

Nit: consider using patterns here
for (final MapEntry(key: name, value: Pair(:outputPath)) in pairs.entries) {
output.assets.data.add(
DataAsset(
package: input.packageName,
name: name,
file: Uri.file(outputPath),
),
);
}

flutter config --enable-dart-data-assets.This is an example of how replacing asset transformers with build/link hooks could look like. The basic idea is that package
vector_graphics_compilerexposes a helper method, herecompileSvg, which is then called in the package's build hook. Options can be set there as well.For now, asset transformers and build hooks can simply co-exist - in the future, when hooks are stable enough, we will want to deprecate asset transformers and move towards this mechanism.
