How to get started

Installation

Add the dependency in your app's pubspec.yaml.

dependencies:
  inappstory_plugin: ^0.8.2

Or run this command:

flutter pub add inappstory_plugin

Android Requirements

Step 1:

Make sure you update your Android SDK versions in app/build.gradle.

minSdkVersion = 23
compileSdkVersion = 34
targetSdkVersion = 34

Step 2:

Initialize Android SDK in your Application class.

warning

Without this, the library will not work on Android devices

Kotlin

package com.example.yourapp

import android.app.Application
import com.inappstory.inappstory_plugin.InAppStoryPlugin

class ExampleApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        // init SDK
        InAppStoryPlugin.initSDK(this)
    }
}

Java

package com.example.yourapp;

import android.app.Application;
import com.inappstory.inappstory_plugin.InAppStoryPlugin;

class ExampleApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        // init SDK
        InAppStoryPlugin.initSDK(this);
    }
}

Step 3:

Extend your MainActivity class from InAppStoryActivity.

Kotlin

package com.example.yourapp

import io.flutter.embedding.android.FlutterActivity
import com.inappstory.inappstory_plugin.activity.InAppStoryActivity


class MainActivity : FlutterActivity()
class MainActivity : InAppStoryActivity()

Java

package com.example.yourapp;

import io.flutter.embedding.android.FlutterActivity;
import com.inappstory.inappstory_plugin.activity.InAppStoryActivity;

class MainActivity extends FlutterActivity(){
class MainActivity extends InAppStoryActivity {
}

Step 4:

Add manifestPlaceholders to your app/build.gradle file

android {
    ...
    defaultConfig {
        ...
        manifestPlaceholders['applicationName'] = '<name of your custom application class>'
    }
}

Why do I need this?

InAppStoryActivity extends FlutterFragmentActivity and intercepts the Back button tap at the Android hardware/software level. This feature is only used when an In-App message (IAM) is shown. It first redirects the tap through the SDK, so pressing the Back button closes the In-App message within the app rather than navigating to another screen. If MainActivity continues to extend FlutterActivity, the Back button bypasses the SDK, and the reader will not close correctly.

iOS Requirements

Make sure you run pod install or pod install --repo-update in the ios folder of your Flutter project.

Basic initialization

Await the plugin return before the use of other API's.

Future<void> initSDK() async {
  await InAppStoryPlugin().initWith(
      '<your api key>',
      '<user id>',
      locale: <locale>,
      cacheSize: CacheSize.medium
  );

  // ... any other calls to API
}

• Parameter userId can be empty.
• Parameter locale used to set up story reader in case, that you need right-to-left direction of interface. It is optional and must be created with region subtag (like Locale('en', 'US')). Otherwise, locale will be default en-US
• Parameter cacheSize is optional and used to changing space of caching stories files (images, videos) (works only on Android devices, default is CacheSize.medium)

CacheSize.small //equal to 15mb;
CacheSize.medium //equal to 110mb, uses by default;
CacheSize.large //equal to 210mb;

Usage

To use the library, add FeedStoriesWidget to your widget tree.

class FeedExample extends StatelessWidget {
  const FeedExample({super.key});

  @override
  Widget build(BuildContext context) {
    return FeedStoriesWidget(
      feed: '<your feed id>',
    );
  }
}

Full example

Full example

import 'package:flutter/material.dart';
import 'package:inappstory_plugin/inappstory_plugin.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final _inAppStoryPlugin = InAppStoryPlugin();

  final apiKey = '<your-api-key>';

  // can be empty
  final userId = '<user-id>';

  final feed = '<your-feed-id>';

  late final initialization = initSdk();

  Future<void> initSdk() async {
    await _inAppStoryPlugin.initWith(apiKey, userId);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('InAppStory Example'),
        ),
        body: FutureBuilder(
          future: initialization,
          builder: (context, initializationSnapshot) {
            if (initializationSnapshot.connectionState ==
                ConnectionState.done) {
              if (initializationSnapshot.hasError) {
                return const Text('SDK was not initialized');
              } else {
                return Column(
                  children: [
                    FeedStoriesWidget(
                      feed: feed,
                    ),
                  ],
                );
              }
            }
            return const Center(
              child: CircularProgressIndicator(),
            );
          },
        ),
      ),
    );
  }
}
