Need InkDecoration equivalent for Flare

[mehmetf]

We have a large Google client who wants to use Flare animations as a Material decoration. That means any kind of interaction on the Material (such as ripples) must be drawn on top of the Flare animation.

Flutter has a widget for this that specifically works for Image widgets (https://api.flutter.dev/flutter/material/Ink/Ink.image.html). We need an Ink.flare() implementation.
