<itemvalue="Reorderable (drag and drop) version of [Wrap], A widget that displays its children in multiple horizontal or vertical runs. In addition to [Wrap]'s parameters, this widget also adds two parameters, [minMainAxisCount] and [maxMainAxisCount], that limits how many children each run has at least and at most. For example, if the size of parent widget allows a run to have more than [maxMainAxisCount] children, the run is forced to end and will have [maxMainAxisCount] children only. All [children] must have a key. See also: [Wrap], which displays its children in multiple horizontal or vertical runs."/>
<itemvalue="The reserved word `null` denotes an object that is the sole instance of this class. The `Null` class is the only class which does not implement `Object`. It is a compile-time error for a class to attempt to extend or implement [Null]. The language contains a number of specialized operators for working with `null` value. Examples: ```dart e1! Throws if e1 is null. e2 ?? e3 Same as e2, unless e2 is null, then use value of e3 x ??= e4 Same as x unless x is null, then same as `x = e4`. e5?.foo() call `foo` on e5, unless e5 is null.
