Is your feature request related to a problem? Please describe.
When I hover some symbol on Dart, I get a documentation section on hover:

I couldn't find a way to disable that section. Note that I don't want to disable the whole popup (which can be done at vscode level), I still need the build errors, the debugger inspections, and even the function prototype. I just want to remove the documentation.

Describe the solution you'd like
A lot of other plugins have an option for that, like:

  "rust-analyzer.hover.documentation.enable": false,
  "html.hover.documentation": false,
  "csharp.referencesCodeLens.enabled": false,

As an example, here's what my config looks like in C#, there's only the full type and a short description appearing:

Is there an option in the Dart extension that I missed? Can you implement one?
