The Ultimate Guide to Cache and Local Storage in Flutter: Comparing Shared Preferences, GetStorage, Hive, and Secure Storage with Key Types

Shared Preferences

A straightforward storage method for key-value pairs, ideal for saving small amounts of data, such as user preferences and settings.

shared_preferences | Flutter package

Code

Future<void> sharedPrefBenchmarks() async {
  final random = Random();
  final Map<String, String> testData = {};
  for (int i = 0; i < 1000; i++) {
    testData['key$i'] = 'value${random.nextInt(10000)}';
  }

  benchmark(() async {
    final prefs = await SharedPreferences.getInstance();
    for (var entry in testData.entries) {
      prefs.setString(entry.key, entry.value);
    }
  }, 'Shared Preferences Write Time');

  benchmark(() async {
    final prefs = await SharedPreferences.getInstance();
    for (var key in testData.keys) {
      prefs.getString(key);
    }
  }, 'Shared Preferences Read Time');
}
