Experimenting : MiniMap

[wer-mathurin]

Since this repository is a good starting point for demoing , understanding and experimenting on the Interactive viewer. A very very good starting point BTW :-)

They idea is to provide an example of how to handle moving to the desire location using a click in the MiniMap. Eventually adding a rectangle in the pan to see what is the portion of the univers you are looking too. This is not trivial to implement it with the current InteractiveViewer api / TransformationController api.

By default, the "unvisited zone" can be grayed out in the MiniMap. We can also add two buttons (+ and -) to change the zooming level programmatically.

After experimenting, I can imagine adding a PanViewer to the InteractiveViewer.builder api.

InteractiveViewer.builder(pan: (_)=> MiniMap(controller: transformationController, builder : () => TheThingsToShow(), showZoomLevel : true ),...);

Like this image, just add a red rectangle to show the pan area.
