Flutter plugin for Live Activities, Use it to create [DynamicIsland UI] and [Lock screen/banner UI],then update them and handle the click action

Flutter Live Activities

This plugin requires notification permission

1. Add a Widget to the iOS project

• Directory structure

2. Edit Runner/Info.plist and live_activity_test/Info.plist

both add:

<plist version="1.0">
<dict>
    ...
	<key>NSSupportsLiveActivities</key>
	<true/>
    ...
</dict>
</plist>

3. Create a data channel in widget swift file

live_activity_test/live_activity_testLiveActivity.swift

import ActivityKit
import SwiftUI
import WidgetKit

// Custom data model
struct TestData {
    var text: String

    init?(JSONData data: [String: String]) {
        self.text = data["text"] ?? ""
    }

    init(text: String) {
        self.text = text
    }
}

// Data channel  <-  Must!
struct FlutterLiveActivities: ActivityAttributes, Identifiable {
    public typealias LiveData = ContentState

    public struct ContentState: Codable, Hashable {
        var data: [String: String]
    }

    var id = UUID()
}

@available(iOSApplicationExtension 16.1, *)
struct live_activity_testLiveActivity: Widget {
    var body: some WidgetConfiguration {
        // Binding
        ActivityConfiguration(for: FlutterLiveActivities.self) { context in

            // Lock screen/banner UI goes here

            // Json to model
            let data = TestData(JSONData: context.state.data)

            // UI
            VStack {
                Text(data?.text ?? "")
            }
            .activityBackgroundTint(Color.cyan)
            .activitySystemActionForegroundColor(Color.black)
        } dynamicIsland: { context in
            // Json to model
            let data = TestData(JSONData: context.state.data)

            // DynamicIsland
            return DynamicIsland {
                // Expanded UI goes here.  Compose the expanded UI through
                // various regions, like leading/trailing/center/bottom
                DynamicIslandExpandedRegion(.leading) {
                    Text("Leading")
                }
                DynamicIslandExpandedRegion(.trailing) {
                    Text("Trailing")
                }
                DynamicIslandExpandedRegion(.bottom) {
                    // Show data from flutter
                    Text(data?.text ?? "")
                }
            } compactLeading: {
                Text("L")
            } compactTrailing: {
                Text("T")
            } minimal: {
                Text("Min")
            }
            .keylineTint(Color.red)
        }
    }
}

4. APIs

import 'package:flutter_live_activities/flutter_live_activities.dart';

...

final FlutterLiveActivities _liveActivitiesPlugin = FlutterLiveActivities();

String? _latestActivityId;

• Check if the liveActivities function is enabled

await _liveActivitiesPlugin.areActivitiesEnabled();

• Get launch url

await _liveActivitiesPlugin.getInitUri()

• Create a live activity

_latestActivityId = await _liveActivitiesPlugin.createActivity(<String, String>{'text': 'Hello World'});

• Update a live activity

if(_latestActivityId != null) {
    await _liveActivitiesPlugin.updateActivity(_latestActivityId!, <String, String>{'text': 'Update Hello World'});
}

• End a live activity

if(_latestActivityId != null) {
    await _liveActivitiesPlugin.endActivity(_latestActivityId!);
}

• End all live activities

await _liveActivitiesPlugin.endAllActivities();

• Get all live activities id

await _liveActivitiesPlugin.getAllActivities()

5. Deeplink

• The default urlScheme is FLA

• Edit urlScheme in your project

• Swift code:

@available(iOSApplicationExtension 16.1, *)
struct live_activity_testLiveActivity: Widget {
    var body: some WidgetConfiguration {
        ActivityConfiguration(for: FlutterLiveActivities.self) { context in
            ...
        } dynamicIsland: { context in

            let data = TestData(JSONData: context.state.data)

            return DynamicIsland {
                ...
                DynamicIslandExpandedRegion(.bottom) {
                    // Create an action via `Link`
                    Link(destination: URL(string: "FLA://xxxxxxx.xxxxxx")!) {
                        Text(data?.text ?? "")
                            .background(.red)
                    }
                }
            } compactLeading: {
                Text("L")
            } compactTrailing: {
                Text("T")
            } minimal: {
                Text("Min")
            }
            .widgetURL(URL(string: "FLA://www.apple.com")) // or use widgetURL
            .keylineTint(Color.red)
        }
    }
}

• Dart code:

_subscription ??= _liveActivitiesPlugin.uriStream(urlScheme: 'FLA').listen((String? uri) {
    dev.log('deeplink uri: $uri');
});
