toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
@override
String toString() {
return 'TListState(page: $page, itemsPerPage: $itemsPerPage, total: $totalItems,'
'displayed: ${displayItems.length}, selected: ${selectedKeys.length}, expanded: ${expandedKeys.length}, '
'\n\tloading: $loading, hasMoreItems: $hasMoreItems, search: $search, '
'$selectionMode, $expansionMode)';
}
