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.
no setterinherited

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 returns null.
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.
