Properties
- db → CommonDatabase?
-
Returns the CommonDatabase.
no setterinherited
- hashCode → int
-
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.
no setterinherited
-
onDelete
→ InternalFinalCallback<
void> -
Internal callback that starts the cycle of this controller.
finalinherited
-
onStart
→ InternalFinalCallback<
void> -
Called at the exact moment the widget is allocated in memory.
It uses an internal "callable" type, to avoid any @overrides in subclases.
This method should be internal and is required to define the
lifetime cycle of the subclass.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
$configureLifeCycle(
) → void -
inherited
-
checksums(
) → Future< List< String> > - Returns the checksums stored in the database.
-
clear(
) → Future< void> - Deletes all the checksums and CacheInfo stored in the database.
-
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.
inherited
-
onInit(
) → void -
Called immediately after the widget is allocated in memory.
You might use this to initialize something for the controller.
inherited
-
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
-
read(
) → Future< CacheInfo?> - Returns the CacheInfo stored in the database.
-
register(
List< String> checksums) → Future<void> -
Stores the provided
checksums
in the database. -
safe<
T> (Future< T> callback(CommonDatabase db), {bool exclusive = true, String? tag}) → Future<T?> -
Runs the
callback
through a non-closed CommonDatabase, or returnsnull
.inherited -
stream<
T> (Stream< T> executor(CommonDatabase db)) → Stream<T> -
Listens to the
executor
through a non-closed CommonDatabase.inherited -
toString(
) → String -
A string representation of this object.
inherited
-
txn<
T> (Future< T> action()) → Future<void> -
Completes the provided
action
as a db transaction.inherited -
unregister(
List< String> checksums) → Future<void> -
Deletes the
checksums
from the database. -
upsert(
CacheInfo? info) → Future< void> -
Creates, updates or deletes the provided
info
in the database. -
watch(
) → Stream< CacheInfo?> - Returns the Stream of real-time changes happening with the CacheInfo.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
