How do you properly handle mouse and keyboard specific interactions in a Flutter web app, such as supporting the scroll wheel, text selection, and right click context menus, which simply do not exist at all on a typical mobile device?

Flutter web apps need to properly account for several specific interaction patterns that a genuine web user would already fully expect but that simply do not exist at all on a typical mobile touch device, including properly supporting mouse scroll wheel input for scrolling through content, allowing a user to genuinely select and copy displayed text using their mouse, and appropriately handling right click events, whether that means displaying your own genuinely custom context menu or deliberately and correctly allowing the browser's own default native context menu to still properly appear as expected.
