Building an AI Agent with Flutter: A Simple Guide

 AI is becoming part of everything these days — chatbots, recommendation systems, virtual assistants, and more. As Flutter developers, we can bring these smart features into our apps too.

In this blog, we’ll learn how to integrate a basic AI agent into a Flutter app using simple tools and APIs. Don’t worry — you don’t need to be a machine learning expert. Just basic Flutter knowledge and some curiosity are enough.

✨ What is an AI Agent?

An AI agent is like a smart assistant. It takes some input (text, voice, image), thinks about it (using some logic or a machine learning model), and gives a useful response.

For example:

• You ask: "What's the weather like today?"

• The AI agent connects to a weather API and replies: "It's sunny with 32°C."

We’ll create something similar using Flutter and OpenAI (ChatGPT).

📃 Tech Stack We’ll Use

• Flutter: To build our app UI

• OpenAI API (ChatGPT): To provide smart responses

• HTTP Package: For making API calls

• GetX or Riverpod (Optional): For state management

⚙️ Step-by-Step Guide

1. Create a Flutter Project

flutter create ai_agent_app
cd ai_agent_app

2. Add Dependencies

In your pubspec.yaml, add:

3. Create a Simple UI

Create a basic chat screen with a TextField and a Send button.

4. Make the API Call

Here’s a simple method to talk to ChatGPT:

🌟 Final Output

Now, you can type something like "What is Flutter" and the app will reply with a smart answer from ChatGPT.
