Flutter preferences management with crypto capabilities

For now preferences are not crypted, I’m waiting for FFI to land 🙂

But you can still use this package to have multiple preferences files in Desktop, mobile and web.

Usage

final preferences = await Preferences.preferences({path: 'pathToPrefs'});

preferences.getBool('boolKey');
await preferences.setBool('boolKey', false);

API

Get and set preference:

Getter have an optional param defaultValue if the preference if not set.

dynamic get(key)

bool getBool(key)

Future<bool> setBool(key, value)

int getInt(key)

Future<bool> setInt(key, value)

double getDouble(key)

Future<bool> setDouble(key, value)

String getString(key)

Future<bool> setString(key, value)

List<String> getStringList(key)

Future<bool> setStringList(key, value)

Custom object save as preferences

You can use save custom object using the mixin WithPreferencesSerializable on your class, it will serialize your object into a map to save it.

Retrieve an object from a preference key: WithPreferencesSerializable getPreferencesSerializable(String key, WithPreferencesSerializable Function(Map<String, Object>))

Retrieve an object from a preference file WithPreferencesSerializable getPreferences(String key, WithPreferencesSerializable Function(Map<String, Object>))

Remove preference:

Future remove(key)

Clear all preference:

Future clear()
