Location class

Class for handling terminal location information.

The acquisition is initiated by doing listen.

It monitors the data at each interval and calls notifyListeners if it has been updated.

LocationData is stored in value, so refer to it.

Terminate acquisition with unlisten.

端末の位置情報を取り扱うクラス。

listenを行うことで取得を開始します。

インターバルごとにデータを監視し更新されていればnotifyListenersを呼び出します。

valueにLocationDataが格納されるのでそこを参照してください。

unlistenで取得を終了します。

Constructors

Location({LocationMasamuneAdapter? adapter})
Class for handling terminal location information.

Properties

adapter → LocationMasamuneAdapter
TAdapter to be used.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
initialized → bool
Returns true if initialized by executing initialize.
no setter
listening → bool
Returns true if listen has already been executed.
no setter
permitted → bool
If permission is granted by executing initialize, returns true.
no setter
permittedBackground → bool
Returns true if initialize is executed and permissions for background are allowed.
no setter
primaryAdapter → LocationMasamuneAdapter
Specifies the default TAdapter if adapter is Null.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
value → LocationData?
The current value of the object. When the value changes, the callbacks registered with addListener will be invoked.
no setteroverride

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).
override
initialize({Duration timeout = const Duration(seconds: 60)}) → Future<void>
Initialization.
listen({LocationAccuracy? accuracy, double? distanceFilterMeters, Duration updateInterval = const Duration(seconds: 1), Duration timeout = const Duration(seconds: 60)}) → Future<void>
Starts acquiring location information.
load({Duration timeout = const Duration(seconds: 60)}) → Future<void>
If location information has not been acquired, location information is acquired only once.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
reload({Duration timeout = const Duration(seconds: 60)}) → Future<void>
Update location information.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
requestPermission({Duration timeout = const Duration(seconds: 60)}) → Future<bool>
Allow location permissions.
setValueInternal(LocationData? value) → void
Set method is used to update the current state.
inherited
toString() → String
A string representation of this object.
inherited
unlisten() → Future<void>
Cancel acquisition of LocationData.

Operators

operator ==(Object other) → bool
The equality operator.

Constants

query → const _$LocationQuery
Query for Location.
