Properties
-
future
→ Future<
void> ? -
Returns itself after the load/save finishes.

- hashCode → int
-

- hasListeners → bool
-
Whether any listeners are currently registered.

Methods
-
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).
inherited
-
initState(
) → void -
The method to be executed when initialization is performed.
inherited
-
load(
) → Future< Result> - Retrieves data and updates the data in the model.
-
loadOnce(
) → Future< Result> - If the data is empty, load is performed only once.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
onDidLoad(
) → Future< void> - Callback after the load has been done.
-
onDidSave(
) → Future< void> - Callback after the save has been done.
-
onLoad(
) → Future< void> - Callback before the load has been done.
-
onSave(
) → Future< void> - Callback before the save has been done.
-
reload(
) → Future< Result> - Reload data and updates the data in the model.
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
save(
) → Future< Result> - Data stored in the model is stored in a database external to the app that is tied to the model.
-
toString(
) → String -
A string representation of this object.

operator ==(
Object other) → bool -
