feat: Improve UX of Mesh Playground

[dario-digregorio]

Feature Description

Hi Renan, I have some UX suggestions for the mesh playground to make it really useful while developing:

• see all vertices simultaneously instead of clicking each to manipulate it.
• code is updated life
• insert my code (Dart IDE?)

• I would also create a PR for these changes if it is possible to contribute for it. I can share more details if necessary.

Hey @dario-digregorio Thanks for those great suggestions.

I plan to expand a lot more on the playground front. Things like saving and sharing and "editing an existing mesh gradient" can be improved once I have a File Format for mesh gradients since files are easier to transport (export & import) than flutter code snippets.

I already have a prototype of live editing mesh files (with hot reload) but that will take a lot of work to be stable.

I will keep this issue open as a way to people add suggestions to the playground.

see all vertices simultaneously instead of clicking each to manipulate it.

This is a good one
