Use case

On iOS, the selection context menu displays default buttons for TextField and SelectableText but not for SelectionArea:

SelectionArea:

SelectableText:

Proposal

Add Share, Look up and Search Web buttons to SelectionArea context menu.

For SelectedText and TextField this was mainly done in the following PRs:

• Share: [Framework] Add Share to selection controls #132599
• Look up: [framework] Add Look Up to selection controls for iOS  #130532
• Search Web: [framework] Add Search Web to selection controls for iOS #131898

For the Share feature to be supported on iPad some work should be done on the engine side (see flutter/engine#48427).
