IOS Widget is not updating - ios

Question

I have an Quote app made in Flutter and now i create widget for IOS. My Widget loads some data from UserDefaults/ Appgroups and depending on that it shows some quotes and a picture. This works with the first start when i press button to set quote and images.
I want the widget to show new quotes every minute, tried different approaches with the Timeline, but it is not working. Can anyone help me make this works?
Below the code for the widget:
func placeholder(in context: Context) -> ExampleEntry {
ExampleEntry(date: Date(), flutterData: FlutterData( title: "Placeholder Title", message: "Placeholder Message",imageId:"tree", textColor:"Color.black"))
}
func getSnapshot(in context: Context, completion: #escaping (ExampleEntry) -> ()) {
let data = UserDefaults.init(suiteName:"***")
let entry = ExampleEntry(date: Date(),flutterData: FlutterData( title: data?.string(forKey: "title") ?? "Set quote and background in Settings > Widget", message: data?.string(forKey: "message") ?? "No Message Set", imageId: data?.string(forKey: "imageId") ?? "Color.black", textColor: data?.string(forKey: "textColor") ?? "Color.white"))
completion(entry)
}
func getTimeline(in context: Context, completion: #escaping (Timeline<ExampleEntry>) -> ()) {
let data = UserDefaults.init(suiteName:"***")
var entries = [ExampleEntry]()
let currentDate = Date()
let entry = ExampleEntry(date: currentDate,flutterData:FlutterData(title: data?.string(forKey: "title") ?? "Set quote and background in Settings > Widget", message: data?.string(forKey: "message") ?? "No Message Set", imageId: data?.string(forKey: "imageId") ?? "Color.black", textColor: data?.string(forKey: "textColor") ?? "Color.white"))
let entryDate = Calendar.current.date(byAdding: .minute, value: 1, to: currentDate)
print(entryDate)
let timeline = Timeline(entries: [entry], policy: .after(entryDate!))
completion(timeline)
}
}
var body: some View {
VStack.init(alignment: .leading, spacing: nil, content: {
Text(entry.flutterData!.title)
.font(.body)
.foregroundColor(Color.white)
.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: Alignment.center)
.padding(.vertical)
.padding(.horizontal,6)

.onReceive(NotificationCenter.default.publisher(for: .NSPersistentStoreRemoteChange)) { _ in
// make sure you don't call this too often
WidgetCenter.shared.reloadAllTimelines()
}
}
)
}
}
var body: some WidgetConfiguration {
StaticConfiguration(kind: kind,provider: Provider()) { entry in

}
