areContentsTheSame(int oldItemPosition, int newItemPosition) → bool

Called by the DiffUtil when it wants to check whether two items have the same data. DiffUtil uses this information to detect if the contents of an item has changed.

override

areItemsTheSame(int oldItemPosition, int newItemPosition) → bool

Called by the DiffUtil to decide whether two object represent the same Item.

override

getChangePayload(int oldItemPosition, int newItemPosition) → Object?

When areItemsTheSame(int, int) returns true for two items and areContentsTheSame(int, int) returns false for them, DiffUtil calls this method to get a payload about the change.

override

getNewItemAtIndex(int index) → T

override

getNewListSize() → int

Returns the size of the new list.

override

getOldItemAtIndex(int index) → T

override

getOldListSize() → int

Returns the size of the old list.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited
