⚠️ Important: Mandatory Migration to Swift Package Manager (SPM)

Due to the official discontinuation of CocoaPods, which will operate in read-only mode, this SDK will no longer receive version updates through CocoaPods after December 2, 2026. The SDK will remain supported through the Swift Package Manager (SPM).

While the plugin currently operates in a hybrid compatibility mode (supporting both CocoaPods and SPM), we strongly recommend that you migrate your project to the Swift Package Manager (SPM) immediately to avoid future compilation failures.

To enable SPM support in your Flutter application, execute:

flutter config --enable-swift-package-manager

flutter_grouplink_sdk

Group Link is an IoT and LaaS technology vendor providing innovative software-based network technology. Its unique approach enables a global Low-Power WAN with unprecedented coverage, leveraging on the connectivity spectrum of surrounding smartphones. GL devices are built under a proprietary, miniaturized and cost-effective design, with no maintenance requirements. Our protocol provides communication at low power between sensors, gateways, and data collection points. These features offer Group Link unique differentials and enable the massification of IoT in a broad range of business applications.‌

Getting Started

To get started, you need to add flutter_grouplink_sdk to your project. Follow the steps below:

Open the terminal in your project root.

Run the following command:

$ flutter pub add flutter_grouplink_sdk

This command will add a line to your package's pubspec.yaml file and run an implicit flutter pub get.

The added line will look like this:

dependencies:
  flutter_grouplink_sdk:

Now in your Dart code, you can use:

import 'package:flutter_grouplink_sdk/flutter_grouplink_sdk.dart';

Usage example

Import flutter_grouplink_sdk

import 'package:flutter_grouplink_sdk/flutter_grouplink_sdk.dart';

Instantiate

For a easier use, you can instantiate the Group Link SDK Plugin:

final _flutterGrouplinkSdkPlugin = GroupLinkSDKPlugin();

startSDK

It's necessary to call the startSDK, startBluetooth and startLocation, so you can use the Group Link SDK Plugin. In main.dart, after the runApp, or at the initState, call the following methods:

await _flutterGrouplinkSdkPlugin.startSDK( [TOKEN] );
await _flutterGrouplinkSdkPlugin.startBluetooth();
await _flutterGrouplinkSdkPlugin.startLocation();

The others methods also can be called after the startSDK, or at the initState.

Atention! To call every method, you will need to add await.
