Not shared data between react native and widget

[Youthleap423]

I have made widget extension with app and tried to share data between them. but It is not working. I can't get data on widget. Can you tell me about issues?

same thing for me, following the instruction on the readme this, I can not get darta on widget. It shows it saves in the app but it does not show up in the widget or userdefault storage

Finally I managed to get it work

• The identifier for app group should have some postfix, for example, your main app identifier is com.domain.myapp, then you app group identifier should be group.com.domain.myapp.store

• In widget side, we can get the data like so in the timeline `

  func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
    let userDefaults = UserDefaults(suiteName:"group.com.domain.myapp.store)
  
    var user: User?
    do {
        let shared = userDefaults?.string(forKey: "user")
        print("data", shared)
  
        if(shared != nil){
            user = try JSONDecoder().decode(User.self, from: shared!.data(using: .utf8)!)
        }
     } catch{
      print(error)
     }
  
    let entry = UserEntry(date: Date(), configuration: ConfigurationIntent(), user: user)
    let timeline = Timeline(entries: [entry], policy: .atEnd)
    completion(timeline)
  }
  

` then in the entry view, you can get this user data by entry.user

• Can also use react-native-widget-bridge, call WidgetBridge.reloadWidget('MyApp_Widget') every time you do some changes

I'm not sure this is the best way to deal with it or not, but it works for me

I think the group identifier can be anything. Make sure to add same App Group and check the check box in both the app and the widget configuration.
