DeviceSettingsController class Null safety
Device Settings controller
Provides access to the current status of the battery/power management. It also leverages the DeviceSettings class from the background geolocation plugin to show Android & vendor-specific Battery / Power Management settings screens

-
The hash code for this object. [...]

- initialized → bool
-
Checks whether the controller has already been initialized.

read / write, override
-
onDelete
→ InternalFinalCallback<
void> -
Internal callback that starts the cycle of this controller.
final, inherited
-
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.
final, inherited
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- settingsOk → dynamic
-
Are all settings ok
read-only

storage
→ ModelStorage<
DeviceSettingsModel> ? -
SimpleStorage to store/retrieve model

Methods
-
$configureLifeCycle(
) → void -
inherited
-
addListener(
GetStateUpdate listener) → Disposer -
Register a closure to be called when the object notifies its listeners.
inherited
-
addListenerId(
Object? key, GetStateUpdate listener) → Disposer -
inherited
-
clearStorage(
) → Future< void> -
Clears the storage
inherited
-
dispose(
) → void -
@mustCallSuper, inherited
-
disposeId(
Object id) → void -
To dispose an
id
from future updates(), this ids are registered byGetBuilder()
or similar, so is a way to unlink the state change with the Widget from the Controller.inherited -
fixPowerSettings(
{required String title, required String powerSavingError, required String batteryOptimizationError, dynamic errorHandler(String, String)?}) → dynamic - Optimize device power settings by calling showPowerSaving and showBatteryOptimizations sequentially. [...]
-
handleStoredModel(
) → Future< void> -
Restores previously saved value if storage is set
inherited
-
listenProviderChange(
) → void - Listen to onProviderChange to be notified when location authorization changes occur.
-
listenToPowerSave(
) → dynamic - Listen to power saving changes
-
loadSettings(
) → Future< void> - Load device settings if not previously set
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
notifyChildrens(
) → void -
@protected, 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(
) → Future< void> -
Restores previously saved value if storage is set
inherited
-
onPowerSaveChange(
[bool? isPowerSaveMode]) → dynamic - Update power saving settings when changed
-
onReady(
) → Future< void> -
Retrieves the settings from the device if not previously set
override
-
refresh(
) → void -
@protected, inherited
-
refreshGroup(
Object id) → void -
@protected, inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that the
object notifies.
inherited
-
removeListenerId(
Object id, VoidCallback listener) → void -
inherited
-
requestGpsPermission(
) → dynamic - Request GPS permission
-
showBatteryOptimizations(
) → dynamic - Show the ignore battery optimizations settings screen.
-
showPowerSaving(
) → Future< void> - Show the battery saver/power manager screen for the user to disable same
-
toString(
) → String -
A string representation of this object. [...]
inherited
-
update(
[List< Object> ? ids, bool condition = true]) → void -
Rebuilds
GetBuilder
each time you callupdate()
; Can take a List ofids
, that will only update the matchingGetBuilder( id: )
,ids
can be reused amongGetBuilders
like group tags. The update will only notify the Widgets, ifcondition
is true.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator. [...]
