Returns true if the maps are both null, or if they are both non-null, have the same length, and contain the same keys associated with the same values. Returns false otherwise. If the elements are maps, lists, sets, or other collectionscomposite objects, then the contents of those elements are not compared element by element unless their equality operators ([Object.==]) do so. For checking deep equality, consider using the [DeepCollectionEquality] class. See also: [setEquals], which does something similar for sets. [listEquals], which does something similar for lists." />
