You can add Xtremepush to your Flutter apps quickly by following our native integration for Android and iOS, then adding a method channel to communicate from your Dart code to the respective platform. Follow our guide below to show how this can be done.

Make sure your mobile apps are added to Xtremepush, following the guides for Android and iOS.

The Xtremepush.dart file and sample integration code can be downloaded here.

Adding the method channel

Add the Xtremepush.dart file to you main lib directory, beside the main.dart file.

Android

In your MainActivity.java class, add the Xtremepush method channel by adding the following:

private static final String CHANNEL = "ie.imobile.xtremepush/flutter";
    @Override
    public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
        super.configureFlutterEngine(flutterEngine);
        new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), CHANNEL)
                .setMethodCallHandler(
                        (call, result) -> {
                            // Note: this method is invoked on the main thread.
                            switch (call.method) {
                                case "hitEvent":
                                    final String xpEvent = call.argument("xpEvent");
                                    mPushConnector.hitEvent(xpEvent);
                                    break;
                                case "hitTag":
                                    final String xpTag = call.argument("xpTag");
                                    mPushConnector.hitTag(xpTag);
                                    break;
                                case "hitTagWithValue":
                                    final String xpTagw = call.argument("xpTag");
                                    final String xpTagValue = call.argument("xpTagValue");
                                    mPushConnector.hitTag(xpTagw, xpTagValue);
                                    break;
                                case "setUser":
                                    final String user_id = call.argument("xp_user_id");
                                    mPushConnector.setUser(user_id);
                                    break;

    companion object {

iOS

In your AppDelegate's didFinishLaunching call, add the method channel like below:

let controller : FlutterViewController = window?.rootViewController as! FlutterViewController
    let xtremepushChannel = FlutterMethodChannel(name: "ie.imobile.xtremepush/flutter",
                                              binaryMessenger: controller.binaryMessenger)
    xtremepushChannel({
      (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
        switch call.method {
        case "hitEvent":
            let xpEvent = call.arguments["xpEvent"] as! String
            XPush.hitEvent(xpEvent)
        case "hitTag":
            let xpTag = call.arguments["xpTag"] as! String;
            XPush.hitTag(xpTag)
        case "hitTagWithValue":
            let xpTag = call.arguments["xpTag"] as! String;
            let xpTagValue = call.arguments["xpTagValue"] as! String;
            XPush.hitTag(xpTag, withValue: xpTagValue)
        case "setUser":
            let userId = call.arguments["xp_user_id"] as! String;
            XPush.setUser(userId)
        case "setTempUser":
            let userId = call.arguments["xp_temp_user_id"] as! String;
            XPush.setTempUser(userId)
        case "openInbox":
            XPush.openInbox()
        case "setSubscription":
            let subscription_flag = (call.arguments["xp_temp_user_id"] as! NSNumber).boolValue;
            XPush.setSubscription(subscription_flag)
        }
    })
[xtremepushChannel setMethodCallHandler:^(FlutterMethodCall* call, FlutterResult result) {
        
    
        if ([@"hitEvent" isEqualToString:call.method]) {
            NSString *xpEvent = call.arguments[@"xpEvent"];
            [XPush hitEvent: xpEvent];
        }
        if ([@"hitTag" isEqualToString:call.method]) {
            NSString *xpTag = call.arguments[@"xpTag"];
            [XPush hitEvent: xpTag];
        }
        if ([@"hitTagWithValue" isEqualToString:call.method]) {
            NSString *xpTag = call.arguments[@"xpTag"];
            NSString *xpTagValue = call.arguments[@"xpTagValue"];
            [XPush hitTag: xpTag withValue:xpTagValue];
        }
        if ([@"setUser" isEqualToString:call.method]) {
            NSString *xpUser = call.arguments[@"xp_user_id"];
            [XPush setUser: xpUser];
        }
        if ([@"setTempUser" isEqualToString:call.method]) {
            NSString *xpUser = call.arguments[@"xp_temp_user_id"];
            [XPush setTempUser: xpUser];
        }
        if ([@"openInbox" isEqualToString:call.method]) {
            [XPush openInbox];
        }
        if ([@"setSubscription" isEqualToString:call.method]) {
            BOOL subscription_flag = [call.arguments[@"subscription_flag"] boolValue];
            [XPush setSubscription: subscription_flag];
        }
      }];

Calling Xtremepush functions from Dart

In your Dart file, import Xtremepush from the Xtremepush.dart file:

import 'Xtremepush.dart';

You can then call the functions using the following:

Xtremepush.hitEvent("string");
Xtremepush.hitTag("string");
Xtremepush.hitTagWithValue("string", "string");
Xtremepush.hitEvent("string");
Xtremepush.setUser("string");
Xtremepush.setTempUser("string");
Xtremepush.openInbox();
Xtremepush.setSubscription(true/false);

👍

Make sure you set the user ID

It is recommended that at this stage you use our SDK method to set user IDs by following our dedicated guide to ensure devices can be associated and targeted in your campaigns by your own unique identifier.
