FitGridLayoutDelegate class

Делегат, который рассчитывает раскладку во время layout-фазы.

Это позволяет избегать rebuild при изменении размеров окна: при ресайзе происходит relayout, а дерево виджетов остаётся неизменным.

FitGridLayoutDelegate({required int itemCount, required int maxItems, required Size itemPadding, required Alignment alignment, required EdgeInsets gridPadding, double? aspectRatio, List<TileSizePreset> presets = tileSizePresets})

alignment → Alignment: final
aspectRatio → double?: final
gridPadding → EdgeInsets: final
hashCode → int: The hash code for this object.

itemCount → int: final
itemPadding → Size: final
maxItems → int: final
presets → List<TileSizePreset>: Список пресетов размеров плитки, из которых выбирается оптимальный.
final
runtimeType → Type: A representation of the runtime type of the object.

getSize(BoxConstraints constraints) → Size: Override this method to return the size of this object given the incoming constraints.
inherited
hasChild(Object childId) → bool: True if a non-null LayoutChild was provided for the specified id.
inherited
layoutChild(Object childId, BoxConstraints constraints) → Size: Ask the child to update its layout within the limits specified by the constraints parameter. The child's size is returned.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
performLayout(Size size) → void: Override this method to lay out and position all children given this widget's size.
override
positionChild(Object childId, Offset offset) → void: Specify the child's origin relative to this origin.
inherited
shouldRelayout(covariant FitGridLayoutDelegate oldDelegate) → bool: Override this method to return true when the children need to be laid out.
override
toString() → String: Override this method to include additional information in the debugging data printed by debugDumpRenderTree and friends.
