Flutter ThingSpeak

Flutter ThingSpeak is a Dart package that provides a client for interacting with ThingSpeak channels. It covers all functionalities of the ThingSpeak API, enabling users to update channel information, fetch and analyze feeds, and query public channels. It is compatible with both the hosted ThingSpeak server at api.thingspeak.com and self-hosted open-source servers.

Getting Started

To use this package, add flutter_thingspeak as a dependency in your pubspec.yaml file:

dependencies:
  flutter_thingspeak: ^1.1.0

Then run:

dart pub get

Usage

import 'package:flutter_thingspeak/flutter_thingspeak.dart';

void main() async {
  final flutterThingspeak = FlutterThingspeakClient(channelID: '12397');

  // Initialize the client
  flutterThingspeak.initialize();

  // Get data from the ThingSpeak channel
  final result = await flutterThingspeak.getAllData();
  print(result);
}
