Static Properties

INSTANCE → Future<SharedPreferences>: no setter

Static Methods

clear() → Future<bool>: Completes with true once the user preferences for the app has been cleared.
containsKey(String? key) → bool: Returns true if persistent storage the contains the given key. Return null if key is null
containsKeyF(String? key) → Future<bool>: Returns true if persistent storage the contains the given key. Return null if key is null
dispose() → void: Best to clean up by calling this function in the State object's dispose() function.
get(String? key) → dynamic: Reads a value of any type from persistent storage. Return null if key is null.
getBool(String? key, [bool? defValue]) → bool: Return false if key is null
getBoolF(String? key, [bool? defValue]) → Future<bool>: Returns a Future. Returns false if key is null.
getDouble(String? key, [double? defValue]) → double: Returns 0 if key is null.
getDoubleF(String? key, [double? defValue]) → Future<double>: Returns a Future. Returns 0 if key is null.
getF(String? key) → Future: Returns a Future. Return null if key is null
getInt(String? key, [int? defValue]) → int: Returns 0 if key is null.
getIntF(String? key, [int? defValue]) → Future<int>: Returns a Future. Returns 0 if key is null.
getKeys() → Set<String>: Returns all keys in the persistent storage.
getKeysF() → Future<Set<String>>: Returns a Future.
getString(String? key, [String? defValue]) → String: Returns '' if key is null.
getStringF(String? key, [String? defValue]) → Future<String>: Returns a Future. Returns '' if key is null.
getStringList(String? key, [List<String>? defValue]) → List<String>: Returns empty List if key is null.
getStringListF(String? key, [List<String>? defValue]) → Future<List<String>>: Returns a Future. Returns empty List if key is null.
init() → Future<SharedPreferences>: Initialize the SharedPreferences object in the State object's iniState() function.
initCalled() → bool: Determine if init was called
ready() → bool: Indicate if Preferences is ready
reload() → Future<void>: Fetches the latest values from the host platform. Use this method to observe modifications that were made in native code (without using the plugin) while the app is running.
remove(String? key) → Future<bool>: Removes an entry from persistent storage. Returns false if key is null.
setBool(String? key, bool? value) → Future<bool>: Saves a boolean value to persistent storage in the background. Returns false if key is null.
setDouble(String? key, double? value) → Future<bool>: Saves a double value to persistent storage in the background. Android doesn't support storing doubles, so it will be stored as a float. Returns false if key is null.
setInt(String? key, int? value) → Future<bool>: Saves an integer value to persistent storage in the background. Returns null if key is null.
setString(String? key, String? value) → Future<bool>: Saves a string value to persistent storage in the background. Returns false if key is null.
setStringList(String? key, List<String>? value) → Future<bool>: Saves a list of strings value to persistent storage in the background. Returns false if key is null.
