Are you looking to configure your ESP8266 or ESP32 devices through a Flutter application? The esptouch_flutter plugin is your go-to solution! This easy-to-use tool allows you to set up network connections effortlessly on both iOS and Android devices. Let’s walk through how to use it effectively!

Getting Started with esptouch_flutter

The esptouch_flutter package wraps the ESP-Touch protocol to help connect your embedded devices to a Wi-Fi network with just a few lines of code. It gives you a customizable interface and implements platform-specific details for seamless integration.

Setting Up the Plugin

To begin, ensure that you have a real device, as the plugin does not function on emulators or simulators. Next, add the plugin to your Flutter project by including it in your pubspec.yaml file:

dependencies:
  esptouch_flutter: ^latest_version

Now, it’s time to write some code!

Code Example

Here’s a basic example to help you kick things off:

import 'package:esptouch_flutter/esptouch_flutter.dart';

// Somewhere in your widget...
final ESPTouchTask task = ESPTouchTask(
  ssid: 'My WiFi network',
  bssid: 'ab:cd:ef:12:23:34',
  password: 'I love SMAHO',
);

final Stream stream = task.execute();

final printResult = (ESPTouchResult result) {
  print('IP: ${result.ip} MAC: ${result.bssid}');
};

StreamSubscription streamSubscription = stream.listen(printResult);

// Cancel your stream subscription after the task is done.
streamSubscription.cancel();

Understanding the Code

Think of the code like a waiter (the plugin) taking your order (your WiFi credentials) and bringing the meal (configuring your device). By specifying the SSID, BSSID, and password, you’re effectively telling the waiter what you want. Once the waiter (plugin) receives the order, they will execute it and bring back confirmation, which you can listen to through a stream.

Customizing Your Tasks

You can customize how long your task runs by using the ESPTouchTaskParameter. For example, if you need the task to wait for an extended period, you can set it like this:

final ESPTouchTask task = ESPTouchTask(
  ssid: 'My WiFi network',
  bssid: 'ab:cd:ef:12:23:34',
  password: 'I love Flutter and ESP-Touch, too', 
  taskParameter: ESPTouchTaskParameter(waitUdpReceiving: Duration(hours: 12)),
);

Troubleshooting Common Issues

• Plugin Not Working: Ensure that you are testing on an actual phone, not an emulator.
• Network Credentials Issue: Double-check your SSID, BSSID, and password for accuracy.
• Multicast Entitlement Error: If you encounter issues with iOS 14.6 or newer, request the com.apple.developer.networking.multicast entitlement.
