# flutter\_smart\_reply

A flutter plugin to wrap Google's Smart Reply library.

https://developers.google.com/ml-kit/language/smart-reply

## Features

With ML Kit's Smart Reply API, you can automatically generate relevant replies to messages. Smart Reply helps your users respond to messages quickly, and makes it easier to reply to messages on devices with limited input capabilities.

## Demo

## Installation

Following steps will help you add this library as a dependency in your flutter project.

- In the `pubspec.yaml` file in the root of your project

```yaml

dependencies:

  flutter_smart_reply: ^0.0.1

```

- Run the following command to get packages:

```bash

$ flutter pub get

```

- In your project-level `build.gradle` file, make sure to include Google's Maven repository in both your buildscript and allprojects sections.

- Add the dependencies for the ML Kit Android libraries to your module's app-level gradle file, which is usually app/build.gradle: 

```gradle

dependencies {

  // ...

  implementation 'com.google.mlkit:smart-reply:16.1.0'

}

```

- Also in your app-level `build.gradle` file, disable compression of tflite files: 

```gradle

android {

    // ...

    aaptOptions {

        noCompress "tflite"

    }

}

```

- Import the package in your project file:

```dart

import 'package:flutter_smart_reply/flutter_smart_reply.dart';

```

## Usage

For a more detailed look at how to use this library, there is a sweet project in the `example` directory and various examples can be found [here](/example/README.md)

A simple example usage is shown below:

```dart

import 'package:flutter_smart_reply/flutter_smart_reply.dart';

void main() {

  runApp(MyApp());

}

class MyApp extends StatefulWidget { ... }

class _MyAppState extends State {

  // a list to track what text messages are added.

  List _textMessages = [];

  // a list to sotre suggested reply messages.

  List _replies = List.empty();

  // whether the message is from local side or remote side

  bool isSelfMode = true;

  // when _textMessages are updated, we call this function to update the suggested replies.

  Future updateSmartReplies() async {

    try {

      _replies = await FlutterSmartReply.getSmartReplies(_textMessages);

    } on PlatformException {}

  }

  @override

  Widget build(BuildContext context) {...}

  

  

  // when a new message text is added, 

  Future _addMessage(String message) async {

    _textMessages.add(isSelfMode

        ? TextMessage.createForLocalUser(message, DateTime.now().millisecondsSinceEpoch)

        : TextMessage.createForRemoteUser(message, DateTime.now().millisecondsSinceEpoch));

    await updateSmartReplies();

    if (!mounted) return;

    isSelfMode = !isSelfMode;

    setState(() {});

  }  

```
