Mopinion Native SDK for Flutter

This Flutter Integration SDK contains code to help you use our Android and/or iOS Native/Web SDKs from Flutter.

Installation

1. Edit the pubspec.yml in your flutter directory to define the Mopinion Plugin Dependency:

dependencies:

  ...

  mopinion_flutter_integration_plugin: ^${latestVersion}

2. Run the following command to get the package:

    flutter pub get

Native set up

Android

1. Open the Android project with Android Studio.
2. Make sure that your MainActivity.kt extends FlutterFragmentActivity and the FlutterEngine is registered as the following:

   import io.flutter.embedding.android.FlutterFragmentActivity
   import io.flutter.embedding.engine.FlutterEngine
   import io.flutter.plugins.GeneratedPluginRegistrant
   
   class MainActivity: FlutterFragmentActivity() {
     override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
       GeneratedPluginRegistrant.registerWith(flutterEngine)
     }
   }
   

3. Make sure the min sdk is 21 in your app build.gradle:

  defaultConfig {
     minSdkVersion 21
 }

4. In your Project build.gradle include the Jitpack repository:

   maven {
     url 'https://www.jitpack.io'
   }
   

5. Sync gradle.
6. Make sure the app theme extends from a MaterialComponent theme. Please check the Android Native SDK readme step 4 for more info.

iOS

Install the Mopinion SDK for iOS to make it an available resource for the Flutter plugin.

1. Open in the terminal the ios folder and run pod install command.
2. Open your iOS project Runner.xcworkspace with Xcode.
3. Click on the Pods project.
4. Click on File option from XCode and click on Add Package dependencies....
5. Search for the Mopinion iOS SDK: https://github.com/Mopinion-com/mopinion-sdk-ios-swiftpm.git It will appear with the name of: mopinion-sdk-ios-swiftpm.
6. Remember to add it to the Pods project.
7. When the dialog of Choose Package Products for mopinion-sdk-ios-swiftpm is opened, select the Add to Target dropdown and from the options select the plugin target: mopinion_flutter_integration_plugin.
8. Add the package.
9. Add Privacy - Camera Usage Description and Privacy - Photo Library Usage Description into file info.plist.

      <key>NSCameraUsageDescription</key>
     <string>TEXT_FOR_END_USER</string>
     <key>NSPhotoLibraryUsageDescription</key>
     <string>TEXT_FOR_END_USER</string>
   

10. Using VSCode, in the folder ios, open the file Podfile and set the iOS Deployment Target to 11.0 or above. Uncomment or add platform :ios, '11.0' to the Podfile.

# Uncomment this line to define a global platform for your project
 platform :ios, '11.0'

11. Finally run the project from XCode.

Flutter implementation

In order to use Mopinion SDK for Flutter and start collecting your valuable user's feedback please follow the following steps:

Import the plugin

Import the plugin class

import 'package:mopinion_flutter_integration_plugin/mopinion_flutter_integration_plugin.dart';

Initialise the SDK

Initialise the SDK by calling:

MopinionFlutterIntegrationPlugin.initSdk("YOUR_DEPLOYMENT_ID", true);

The parameter log which is the boolean after the key, allows to activate the logging in the SDK. It's recommended to initialise the SDK the earliest possible, an example of where to initialise the SDK:

  @override
  void initState() {
    super.initState();
    initialize();
  }

  Future<void> initialize() async {
    try {
       MopinionFlutterIntegrationPlugin.initSdk("YOUR_DEPLOYMENT_ID", true);
    } on PlatformException {
      print("error");
    } 
  }

Calling events

In order to show your forms, call the function :

MopinionFlutterIntegrationPlugin.event("EVENT_NAME");

The MopinionFlutterIntegrationPlugin.event("EVENT_NAME") function will also stream an Form State to show in which state the form is. To be able to listen to that callback you can call the function MopinionFlutterIntegrationPlugin.eventsData() which returns an Stream. Example of usage:

    Stream stream;
    try {
      stream = await MopinionFlutterIntegrationPlugin.eventsData();
      stream.listen(_setTextEventName, onError: _onError);
    } on PlatformException {
      print("Failed to get events stream.");
    }

    void _setTextEventName(event) {
    setState(() => _yourState_ = event);
  }

The Form State callback will be a String, and these are the possible Form States:

• Loading ¹
• NotLoading ¹
• FormOpened
• FormSent
• FormCanceled
• FormClosed
• Error
• HasNotBeenShown

More information about the Form States can be found in each readme of the Native SDKs:

iOS: 2.4.2 Callback variants of the event method Android: Implementing Form State callbacks

¹ These form states are only available in the Android SDK by the moment.

Adding Metadata

Adding Metadata in the Mopinion SDK is easy, it's achieved by calling the function

  MopinionFlutterIntegrationPlugin.data(Map);

This function will receive a Map<String, String> variable which will contain the metadata you want to set in your events. Example of usage:

  Map<String, String> map = {
        "age": "29",
        "name": "Manuel"
      };
  MopinionFlutterIntegrationPlugin.data(map);
  MopinionFlutterIntegrationPlugin.event(yourEvent);

Deleting Metadata by key

When a key data from the Metadata Map<String, String> provided to the SDK wants to be deleted then we should just pass the key value as the following:

  MopinionFlutterIntegrationPlugin.removeMetaData("name");

This will remove the key name from the Metadata Map provided.

Deleting all Metadata

When all Metadata wants to be deleted, it's even simpler, just call

MopinionFlutterIntegrationPlugin.removeAllMetaData();

And all Metadata will be deleted.
