Properties

controller → EndlessStreamController<T>?
The stream controller used to perform actions on the grid view such as loading more data or clearing the grid.
final
emptyBuilder → Widget Function(BuildContext context)?
The builder function for the grid view empty state.
final
emptyBuilderState → EndlessStateProperty?
The state property for the grid view empty state.
final
extentAfterFactor → double?
The fraction of the remaining quantity of content conceptually "below" the viewport in the scrollable relative to the maximum height of the scrollable region at which point loadMore should be called to load more data.
final
footerBuilder → Widget Function(BuildContext context)?
The builder function for the grid view footer.
final
footerBuilderState → EndlessStateProperty?
The state property for the grid view footer.
final
gridDelegate → SliverGridDelegate
Controls the layout of tiles in a grid. See GridView.gridDelegate
final
hashCode → int
The hash code for this object.
no setterinherited
headerBuilder → Widget Function(BuildContext context)?
The builder function for the grid view header.
final
headerBuilderState → EndlessStateProperty?
The state property for the grid view header.
final
itemBuilder → dynamic Function(BuildContext context, {required int index, required T item, required int totalItems})

finalinherited
loadingBuilder → Widget Function(BuildContext context)?
The builder function for the grid view loading state.
final
loadingBuilderState → EndlessStateProperty?
The state property for the grid view loading state.
final
loadMore → void Function()
A function which adds more items to the stream when the grid view is scrolled to its threshold for loading more items determined by the extentAfterFactor.
final
loadMoreBuilder → Widget Function(BuildContext context)?
The builder function for the grid view load more action widget.
final
loadMoreBuilderState → EndlessStateProperty?
The state property for the grid view load more action widget.
final
loadOnSubscribe → bool?
Whether to immediately request data from the stream when it is first subscribed to by calling the EndlessStreamGridView.loadMore API.
final
onStateChange → void Function(Set<EndlessState> states)?
A callback function that provides the current states of the endless scroll view whenever they change.
final
padding → EdgeInsets?
The padding around the scroll view.
final
physics → ScrollPhysics?
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scrollController → ScrollController?
