使用 flutter_secure_storage 保存数据的列表文本......这可能吗？

Question

iam using flutter_secure_storage in my Flutter app ...

iam Saving data as a key with it is take a value of String like this :

 await storage.write(key: 'currntUserID', value: 'userid');

and iam reding it like this :

urrntUserID = (await storage.read(key: 'currntUserID'))!;

but urrntUserID it just a String !

but what if i have a List of Strings ... is there any way to save thiam all in the storage ?

What i need is like if i have :

List<String> listviewerbulderstring = ['a1','a2','a3']

What i need to do is like call the array to = the Saved array in the storeg somthing like this :

List<String> listviewerbulderstring = (await storage.read(key: 'listofiteams'))!;

is this even possible ? or there is better way to do this ?

Answer 1

This can be achieved by using JSON serialization like so:

void myFunction() async {
  const storage = FlutterSecureStorage();
  List<String> listviewerbulderstring = ['a1','a2','a3'];
  await storage.write(key: 'listofitems', value: jsonEncode(listviewerbulderstring));
  String? stringofitems = await storage.read(key: 'listofitems');
  List<dynamic> listofitems = jsonDecode(stringofitems!);
  print(listFromJson);    
}
