How to set a Laravel Nova field to display as readonly or protected?

This capability was added in v1.1.4 (October 1, 2018).

Example usage:

Text:: make('SomethingImportant')
    ->withMeta(['extraAttributes' => [
          'readonly' => true
    ]]),

As of v2.0.1, readonly() is native and accepts a callback, closure or boolean and can simply be called as:

Text::make('Name')->readonly(true)

This may have been added prior to this version but the changelog does not specify if this is the case.
