DragMixin mixin
this mixin allow to fetch data when the scroll is at the bottom or on the top
- Superclass constraints
Properties

-
The hash code for this object.
no setterinherited
- initialized → bool

Checks whether the controller has already been initialized.
no setterinherited
- isClosed → bool
-
Checks whether the controller has already been closed.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onClose(
) → void -
Called before onDelete method. onClose might be used to
dispose resources used by the controller. Like closing events,
or streams before the controller is destroyed.
Or dispose objects that can potentially create some memory leaks,
like TextEditingControllers, AnimationControllers.
Might be useful as well to persist some data on disk.
override
-
onDelete(
) → void -
inherited
-
onEndScroll(
) → Future< void> - this method is called when the scroll is at the bottom
-
onInit(
) → void -
Called immediately after the widget is allocated in memory.
You might use this to initialize something for the controller.
override
-
onReady(
) → void -
Called 1 frame after onInit(). It is the perfect place to enter
navigation events, like snackbar, dialogs, or a new route, or
async request.
inherited
-
onStart(
) → void -
Called at the exact moment the widget is allocated in memory.
It uses an internal "callable" type, to avoid any @overrides in subclasses.
This method should be internal and is required to define the
lifetime cycle of the subclass.
inherited
-
onTopScroll(
) → Future< void> - this method is called when the scroll is at the top
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
