Examples for using the esptouch_flutter plugin

The example app demonstrates how to use the esptouch_flutter plugin.

You can read the full source code on GitHub: example folder in the esptouch_flutter repository. This example is a fully-configurable, fully-functional ESP Touch app that lets you configure all parameters and WiFi details (with the option of automatically recognizing the current network).

There is also another example app that is available and it's available at smaho-engineering/esptouch_flutter_kotlin_example. It's a much simpler app and you will need to edit the source code in order to enter the WiFi credentials to the simple example app.

The example app lets you configure

• WiFi SSID (WiFi name)
• WiFi BSSID (MAC of the wireless access point)
• Password
• Duration of the task
• Expected task count
• ... many more.

You can use current network SSID/BSSID or enter it manually (getting wifi info is restricted on the platforms, so sometimes it's necessary to enter them manually).

You can run the example app by:

flutter packages get
cd example
flutter run

Screenshots

When you run the example app, this is more or less what you should expect:

Simple config

Set WiFi details, such as name, address and password. All fields are editable.

Advanced config

You can configure all task parameters right from your Flutter app. This level of configurability is not even supported in the official example apps.

Code snippets

In the code example, I specify the types for clarity. You can omit them as Dart can infer them.

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<ESPTouchResult> stream = task.execute();
StreamSubscription<ESPTouchResult> streamSubscription = stream.listen((ESPTouchResult result) {
  print('Configured IP: ${result.ip} MAC: ${result.bssid}');
});
// Don't forget to cancel your stream subscription:
streamSubscription.cancel();

If you would like to customize the task, provide ESPTouchTaskParameter instance as taskParameter to ESPTouchTask.

final ESPTouchTask task = ESPTouchTask(
  ssid: 'My WiFi network',
  bssid: 'ab:cd:ef:12:23:34',
  password: 'The esptouch flutter plugin is awesome',
  taskParameter: ESPTouchTaskParameter(waitUdpReceiving: Duration(hour: 12)),
);
// You can still stop the task at any point by calling .cancel on the stream subscription:
streamSubscription.cancel();

In a real world example, you could display the result to the user, save it locally in SQLite or send it to your backend.

Get WiFi details

Quite often, you want to provide an easy way for getting the current WiFi network's SSID and BSSID. Use the connectivity and wifi_info_flutter plugins for discovering the state of the network (WiFi & mobile/cellular) connectivity on Android and iOS.

In the example app, we wrote the platform-specific code that fetches the WiFi details instead of using the connectivity plugin. See what you need to add to your platform code in MainActivity.java and AppDelegate.m. For most cases, though, I recommend you to use the connectivity plugin, as it's well tested, frequently updated and it's maintained by the Flutter team.
