<itemvalue="Convenience method to index the field. If you would like to create a composite index instead, see: Index. Returns: True if this field should be indexed, false otherwise. Defaults to false."/>
<itemvalue="Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero)."/>
<itemvalue="Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. See the description of the class Date for a discussion of slight discrepancies that may arise between "computer time" and coordinated universal time (UTC). Returns: the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC."/>
<itemvalue="A physical separation with a hinge that allows two display panels to fold."/>

<itemvalue="The area of the flutter view occupied by this display feature, measured in logical pixels. On devices with two screens, the Flutter view spans from the top-left corner of the left or top screen to the bottom-right corner of the right or bottom screen, including the visual area occupied by any display feature. Bounds of display features are reported in this coordinate system. For example, on a dual screen device in portrait mode: [bounds.left] gives you the size of left screen, in logical pixels. [bounds.right] gives you the size of the left screen + the hinge width."/>
<itemvalue="Creates a sorted list of the elements of the iterable. The elements are ordered by the natural ordering of the property [keyOf] of the element."/>
