# Flutter SDK

{% hint style="info" %}
Latest release: **Version** **0.0.16**
{% endhint %}

## Overview

The Identomat Flutter SDK provides a Flutter interface for starting an Identomat verification session in a mobile application using a session key.

The SDK is responsible for:

* Initializing the Identomat verification flow
* Launching the verification UI
* Communicating with the native Identomat implementation

## Getting started

### Depend on it

Run this command:

```sh
 $ flutter pub add identomat_flutter
```

This will add a line like this to your package's `pubspec.yaml` (and run an implicit `flutter pub get`):

```
dependencies:
  identomat_flutter: ^0.0.11
```

Alternatively, your editor might support `flutter pub get`. Check the docs for your editor to learn more.

### Import it

In your Dart code, you can use:

```
import 'package:identomat_flutter/identomat.dart';
import 'package:identomat_flutter/identomat_flutter_method_channel.dart';
import 'package:identomat_flutter/identomat_flutter_platform_interface.dart';
```

## Example

**example/lib/main.dart**

```
import 'package:flutter/material.dart';
import 'dart:async';

import 'package:identomat_flutter/identomat.dart';
import 'package:identomat_flutter_example/data.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 identomat = Identomat();
  TextEditingController myController = TextEditingController();
  final formKey = GlobalKey<FormState>();

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState(String sesstionKey) async {
    identomat.setCallback(
      () {
        print('===========>>> ONCALL');
      },
    );
    await identomat.setBaseUrl(data['baseUrl']);
    await identomat.setColors(data['colors']);
    await identomat.setStrings(data['strings']);
    await identomat.start(sesstionKey);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Padding(
            padding: const EdgeInsets.all(16),
            child: Form(
              key: formKey,
              child: Column(
                mainAxisAlignment: MainAxisAlignment.center,
                children: [
                  TextFormField(
                    controller: myController,
                    decoration:
                        const InputDecoration(hintText: 'Enter session key'),
                    validator: (text) {
                      if (text == null || text.trim().isEmpty) {
                        return 'Session key is empty';
                      }
                      return null;
                    },
                  ),
                  const SizedBox(
                    height: 20,
                  ),
                  ElevatedButton(
                    onPressed: () {
                      FocusManager.instance.primaryFocus?.unfocus();
                      if (formKey.currentState!.validate()) {
                        initPlatformState(myController.text.trim());
                      }
                    },
                    child: const Text('Click'),
                  ),
                ],
              ),
            ),
          ),
        ),
      ),
    );
  }
}
