Мобильная версияПростое Live Activity отображается правильно, но когда я переключился на более подробный макет Live Activity, на экране блокировки ничего не появляется, или Dynamic Island не вызывает ошибок от Flutter.
Рабочий код:
MineAppWidgetLiveActivity.swift
import ActivityKit
import WidgetKit
import SwiftUI
// 1. ATTRIBUTES
struct LiveActivitiesAppAttributes: ActivityAttributes, Identifiable {
public struct ContentState: Codable, Hashable {
var score: String
}
var matchName: String
}
extension LiveActivitiesAppAttributes {
func prefixedKey(_ key: String) -> String {
"\(id)_\(key)"
}
}
let sharedDefault = UserDefaults(suiteName: "group.com.example.appLiveActivitytest")!
struct MineAppWidgetLiveActivity: Widget {
var body: some WidgetConfiguration {
ActivityConfiguration(for: LiveActivitiesAppAttributes.self) { context in
VStack {
Text("
\(context.attributes.matchName)").font(.headline)
Text(context.state.score)
.font(.title)
}
.padding()
} dynamicIsland: { context in
DynamicIsland {
DynamicIslandExpandedRegion(.center) {
Text("Score: \(context.state.score)")
}
} compactLeading: {
Text("

Text(context.state.score)
} minimal: {
Text("

}
}
}

const MyApp({super.key});
@override
State createState() => _MyAppState();
}
class _MyAppState extends State {
final _liveActivitiesPlugin = LiveActivities();
String? _latestActivityId;
@override
void initState() {
_liveActivitiesPlugin.init(
appGroupId: 'group.com.example.appLiveActivitytest',
requestAndroidNotificationPermission: true,
);
super.initState();
}
Future start() async {
_latestActivityId = await _liveActivitiesPlugin.createActivity(
DateTime.now().millisecondsSinceEpoch.toString(),
{"score": "0 - 0"},
);
setState(() {});
}
Future update() async {
if (_latestActivityId == null) return;
final asd = await _liveActivitiesPlugin.updateActivity(_latestActivityId!, {
"score": "5 - 3",
});
log(asd.toString());
}
Future stop() async {
if (_latestActivityId == null) return;
_liveActivitiesPlugin.endAllActivities();
_latestActivityId = null;
setState(() {});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: const Text("Live Activities Test")),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [

ElevatedButton(onPressed: stop, child: const Text("Stop")),

}
