Adds session functionality to Flutter. Works on both mobile, web and (hopefully) desktop apps

flutter_session

Adds session support to Flutter. Works with mobile, web and (hopefully) desktop builds. (Don't forget to hit the like button if you find the package helpful.)

Write values to the session:

await FlutterSession().set("token", myJWTToken);

or

var session = FlutterSession();
await session.set("token", myJWTToken);
await session.set("name", "jhourlad");
await session.set("id", 1);
await session.set("price", 10.50);
await session.set("isOK", true);

Saving objects, make sure that it has the toJson() method. See https://ashamp.github.io/jsonToDartModel:

class Data {
  final int id;
  final String data;

  Data({this.data, this.id});

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = Map<String, dynamic>();
    data["id"] = id;
    data["data"] = this.data;
    return data;
  }
}

Data mappedData = Data(id: 1, data: "Lorem ipsum something, something...");
await FlutterSession().set('mappedData', mappedData);

Read values from the session:

dynamic token = await FlutterSession().get("token");

Session persists throughout the app's lifetime. (Don't forget to hit the like button if you find the package helpful.)

flutter_session's Issues

version solving failed

am building a Flutter web app and I wanted to add sessions, so I tried adding the flutter_session package using flutter pub add flutter_session but I get this error

Because shared_preferences_linux >=0.0.4-nullsafety <2.0.0 depends on shared_preferences_platform_interface ^2.0.0-nullsafety and shared_preferences_linux <=0.0.2 depends on path_provider ^1.6.11, shared_preferences_linux <0.0.2+1 or >=0.0.4-nullsafety <2.0.0-∞ requires shared_preferences_platform_interface ^2.0.0-nullsafety or path_provider ^1.6.11.

And because google_fonts >=2.0.0 depends on path_provider ^2.0.0 and every version of flutter_session depends on shared_preferences ^0.5.8, google_fonts >=2.0.0 is incompatible with flutter_session.

i tried removing google_fonts package but the same issue remained but this time with other packages.

Remove/unset

Is there an option currently?

Session not cleared after closing browser

I use the session to store adminId in one of my apps but after the app *web browser) closes, the session is not cleared (user always logged in)

how add multiple maps

Hello guys, i need helpe.
how add multiple maps ?
Exemple: {id:1,name:test},{id:2,name:test2}

how to give session timeout in this

there is a problem when add list string

List data = List();
data.add('${map['id']}:${map['valor']}');
await FlutterSession().set("beneficios", data);

Exception has occurred.
NoSuchMethodError (NoSuchMethodError: Class 'List' has no instance method 'toJson'.
Receiver: Instance(length:1) of '_GrowableList'
Tried calling: toJson())

  // List<String>
  case List:
    {

    }

Clear

Possibility to remove all sessions?

SharedPreferences preferences = await SharedPreferences.getInstance();
await preferences.clear();

null safety

can u guys please update the package to support null safety thank you.

flutter 2.x bug

Hello sir.

flutter_session seems to be incompatible with other third-party libraries.

Can you schedule an update to the null safe version recently?

[study] flutter pub get
Running "flutter pub get" in study...
Because study depends on flutter_session ^0.1.1 which depends on shared_preferences ^0.5.8, shared_preferences ^0.5.8 is required.

So, because study depends on shared_preferences ^2.0.3, version solving failed.
pub get failed (1; So, because study depends on shared_preferences ^2.0.3, version solving failed.)
exit code 1

Add A New Feature To check if session contains any particular key

currently the package doesn't support to check if session contains any particular key.

for example:
bool isset = await FlutterSession().contains('key')

Web issue with runtimetype

If I create a session variabel like this:

FlutterSession().set('token', '12345');

then on web, the token will be stored like an integer and not a string.

Is it probable a issue with the webbuild and not your package?
