get secure storage

get_secure_storage #
A cryptography Secure version of GetStorage originally written by Jonny Borges (https://github.com/jonataslaw/get_storage).
GetSecureStorage is a secure, fast, extra light and synchronous key-value in memory, which backs up data to disk at each operation. It is written entirely in Dart and is based on the Cryptography dart package.
The cryptography library used is https://pub.dev/packages/cryptography
The algorithm used is 128bit AES-CTR with MAC sha256
Supports Android, iOS, Web, Mac, Linux, and Windows.
Can store String, int, double, Map and List
Add to your pubspec: #

Install it #
You can install packages from the command line:
with Flutter:
$ flutter packages get

Import it #
Now in your Dart code, you can use:
import 'package:get_secure_storage/get_secure_storage.dart';
copied to clipboard
Initialize storage driver with await: #
main() async {
await GetSecureStorage.init(password: 'strongpassword');
runApp(App());
}
copied to clipboard
use GetSecureStorage through an instance or use directly GetSecureStorage().read('key')
final box = GetSecureStorage(password: 'strongpassword');
copied to clipboard
To write information you must use write :
box.write('quote', 'GetSecureStorage is the best');
copied to clipboard
To read values you use read:
print(box.read('quote'));
// out: GetSecureStorage is the best

copied to clipboard
To remove a key, you can use remove:
box.remove('quote');
copied to clipboard
To listen changes you can use listen:
Function? disposeListen;
disposeListen = box.listen((){
print('box changed');
});
copied to clipboard
If you subscribe to events, be sure to dispose them when using:
disposeListen?.call();
copied to clipboard
To listen changes on key you can use listenKey:
box.listenKey('key', (value){
print('new key is $value');
});

To erase your container:
box.erase();

If you want to create different containers, simply give it a name. You can listen to specific containers, and also delete them.
GetSecureStorage g = GetSecureStorage(container:'MyStorage', password: 'strongpassword');
copied to clipboard
To initialize specific container:
await GetSecureStorage.init(container:'MyStorage', password: 'strongpassword');

SharedPreferences Implementation #
class MyPref {
static final _otherBox = () => GetSecureStorage(container:'MyPref', password: 'strongpassword');

final username = ''.val('username');
final age = 0.val('age');
final price = 1000.val('price', getBox: _otherBox);

// or
final username2 = ReadWriteValue('username', '');
final age2 = ReadWriteValue('age', 0);
final price2 = ReadWriteValue('price', '', _otherBox);
}

...

void updateAge() {
final age = 0.val('age');
// or
final age = ReadWriteValue('age', 0, () => box);
// or
final age = Get.find<MyPref>().age;

age.val = 1; // will save to box
final realAge = age.val; // will read from box
