Methods

add(T newItem, {bool isQuiet = false}) → Future<void>
Add a new item to the end of data list. Set isQuiet = true to avoid rendering loading state, default false.
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
onAdd(T newItem) → Future<T>
Called when trying to add a new item, Must return the added item, or throw an error if it's failed to add.
onFetch() → Future<List<T>>
Called when trying to fetch data for initial or on refreshing. Must return a list of data as the result, or throw an error when it's failed to fetch.
onRemove(int index) → Future<int>
Called when trying to remove an item. Must return the removed item, or throw an error when it's failed to remove.
refresh({bool isQuiet = false}) → Future<void>
Refresh value of data by recall fetch. Set isQuiet = true to avoid rendering loading state, default false.
removeAt(int index, {bool isQuiet = false}) → Future<void>
Remove the item at index. Set isQuiet = true to avoid rendering loading state, default false.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
toString() → String
