In this technical blog post, we will walk through the process of creating a travel itinerary app using Flutter and integrating the OpenAI ChatGPT API. By leveraging the cross-platform capabilities of Flutter and the conversational intelligence of ChatGPT, we can develop an app that assists users in planning their trips and generates personalized itineraries based on their preferences.
Step 1: Setting Up the Development Environment
Install Flutter: Follow the official Flutter installation guide for your operating system.
Set Up an Editor: Choose an IDE or text editor for Flutter development, such as Visual Studio Code or Android Studio, and install the necessary plugins and extensions.
Step 2: Creating a New Flutter Project
Open your terminal or command prompt and run the command flutter create your_app_name to create a new Flutter project.
Step 3: Adding Dependencies
chat_gpt_sdk: ^2.1.7
Step 4: Designing the User Interface and Integrating OpenAI ChatGPT API
I developed a basic user interface using the Dart language to gather user
input. The input will be used as a variable in the prompt for Chat GPT. Upon
submission, the UI will generate a travel itinerary based on the provided user
data.
OpenAI ChatGPT API:
Create an OpenAI account and obtain an API key for authentication.You can find the API key at here.
Note: No free version of Chat GPT API is available now. However, you can start for free with $5 in free credit that can be used during your first 3 months. Check details here
Chat GPT SDK
There is a SDK wrapper for OpenAI's APIs in Flutter, which assists in
seamlessly integrating ChatGPT into your Flutter applications.
Add Chat GPT SDK and import it in your file and use following code to
request and get response from Open AI's Chat GPT.
