Note: Graphite is a relatively new and experimental GPU rendering backend within Skia, and as of now, Flutter does not officially support it out-of-the-box. Integrating Graphite into Flutter involves building a custom Flutter engine with the appropriate Skia flags enabled. The process below assumes familiarity with building the Flutter engine from source and working with GN/Ninja build systems.

Prerequisites:

A working Flutter engine development environment:
- Follow the official Flutter engine build instructions: https://github.com/flutter/engine/blob/main/CONTRIBUTING.md
A platform that supports Graphite’s current GPU backends (e.g., Metal on macOS/iOS or Dawn on certain platforms).

Issue Explanation

The reported error involves a runtime crash when the vector_graphics package attempts to draw an <image> element from an SVG. The stack trace suggests a TypeError is happening during onDrawImage, likely due to the decoding of image bytes into a Dart/Flutter UI image object not producing the expected type.

Prior to Flutter 3.10, decodeImageFromList was the conventional method to decode images from byte arrays. However, with updated Flutter versions and web compatibility changes, decodeImageFromList on the web may not return the expected ui.Image type, causing type errors at runtime. Instead, it's recommended to use the newer image decoding approach that involves ImmutableBuffer, ImageDescriptor, and Codec.

Root Cause

The onDrawImage method in FlutterVectorGraphicsListener is expecting a ui.Image, but the decoding method used might be returning something else or failing silently, leading to a TypeError.
If the code previously relied on `decodeImageFrom
