shared_preference_app_group 2.1.0

Shared preferences for iOS and macOS App Groups (using `-[NSUserDefaults initWithSuiteName:]`)

Shared preferences with App Group

Shared preferences for iOS and macOS App Groups (using -[NSUserDefaults initWithSuiteName:])

Note: Supports iOS and macOS

Compatibility

This plugin currently supports:

• Flutter >=3.41.0
• Dart >=3.11.0
• iOS >=13.0
• macOS >=10.15

The iOS and macOS implementations support both CocoaPods and Swift Package Manager. Swift Package Manager is the default dependency manager for newer Flutter projects, while CocoaPods remains supported for existing projects.

On macOS, App Groups require the app to use the App Sandbox capability and to list the group identifier under com.apple.security.application-groups in its .entitlements file. The value passed to setAppGroup must exactly match an identifier in the entitlements file; this plugin does not add a team identifier automatically.

Usage

To use this plugin, add shared_preference_app_group as a dependency in your pubspec.yaml file.

Example

// The app group must be set up first
await SharedPreferenceAppGroup.setAppGroup(appGroupID);

// Set values using [[NSUserDefaults alloc] initWithSuiteName:appGroupID]
await SharedPreferenceAppGroup.setBool('MY_BOOL_KEY', true);
await SharedPreferenceAppGroup.setString('MY_STRING_KEY', 'STRING_VALUE');
await SharedPreferenceAppGroup.setInt('MY_INT_KEY', 42);
await SharedPreferenceAppGroup.setDouble('MY_DOUBLE_KEY', 9.9);
await SharedPreferenceAppGroup.setStringList('MY_STRING_ARRAY', ["element1", "element2", "element3"]);

// Get values
bool boolValue = await SharedPreferenceAppGroup.getBool('MY_BOOL_KEY') ?? false;
String stringValue = await SharedPreferenceAppGroup.getString('MY_STRING_KEY') ?? 'null';
int intValue = await SharedPreferenceAppGroup.getInt('MY_INT_KEY') ?? 0;
double doubleValue = await SharedPreferenceAppGroup.getDouble('MY_DOUBLE_KEY') ?? 0.0;
List<String> stringArrayValue = await SharedPreferenceAppGroup.getStringList('MY_STRING_ARRAY') ?? [];

Please see the example app of this plugin for a full example.
