ChatGPT Tutorial for Flutter: Getting Began


The tech house is all about AI and what it could do proper now. A part of it is because of OpenAI’s ChatGPT, a chat app powered by their Generative Pre-Educated mannequin. This lets you draft paperwork, reply questions on a subject, and even write code.

On this tutorial, you’ll get began with ChatGPT through the use of it to construct a easy trivia app referred to as Wizz. Use OpenAI API as your app’s enterprise logic supplier as an alternative of utilizing customized backend companies. Within the course of, you’ll study the next:

  • The fundamentals of what ChatGPT is.
  • Perceive the capabilities of the GPT language mannequin.
  • To leverage the language mannequin utilizing finest practices.

  • take care of surprising responses from the mannequin.

Time to dive into the thrilling world of AI!

Getting Began

Obtain the starter challenge by clicking the Obtain Supplies button on the prime or backside of this tutorial. Then, open the starter challenge in VS Code. You can too use Android Studio, however you’ll need to adapt the directions under as wanted.

It’s best to use a current model of Flutter 3.10.1 or above. Be sure that to get the newest dependencies for the challenge by operating flutter pub get out of your Terminal or instantly from the VS Code immediate.

Wanting on the code, you’ll discover the starter challenge already supplies some UI for the trivia app. Right here’s a fast overview of the code construction:

  • prompts.dart: This file will include three prompts that’ll be despatched to the mannequin.
  • information.dart: A layer that’ll work together with OpenAI’s API.
  • area.dart: Defines the completely different enterprise logic fashions of Wizz, together with Questions and Hints.
  • pages: All screens are below this folder.
  • widgets: Incorporates a number of elements of UI.

Construct and run the challenge. It’s best to see a display screen asking for the participant’s identify, as proven under.

Wizz app: starting screen

Observe: In case you see the error Error (Xcode): The sandbox shouldn’t be in sync with the Podfile.lock. Run ‘pod set up’ or replace your CocoaPods set up. – use the next terminal command to repair it cd ios && pod set up && cd ..

Kind your identify within the enter and press Let’s Wizz Up to start out a brand new recreation.

Game Screen with a Placeholder

The trivia recreation is incomplete for the reason that recreation display screen is only a placeholder. You’ll add the core options for Wizz all through the tutorial.

Understanding ChatGPT’s Capabilities

Probably the most well-known AI-powered apps is ChatGPT. In easy phrases, ChatGPT is an AI system created and skilled by OpenAI to grasp and generate human language.

The final three letters within the identify stand for Generative Pre-Educated Transformers. GPT refers to a broader household of language fashions primarily based on a particular structure. These fashions are skilled on a considerable amount of information to generate human-like content material, equivalent to textual content, photos and even music.

GPT-based fashions can often enable you to construct functions that assist you to:

  • Write paperwork.
  • Reply questions.
  • Analyze textual content.
  • Create an interactive chatbot.
  • Translate completely different languages.
  • Generate code.
  • Resolve bugs in a code block.
  • And a lot extra.

ChatGPT is a particular implementation of a GPT mannequin. OpenAI constructed it for having chat-based human conversations. When integrating it into your app, understanding the distinction between ChatGPT and its underlying GPT mannequin is important.

The primary distinction between ChatGPT and GPT lies of their meant use circumstances and design concerns. OpenAI designed ChatGPT to have interaction in back-and-forth conversations with customers. GPT fashions depend on prompts to generate responses. These prompts set the tone and supply context for the generated textual content. In distinction, ChatGPT was optimized for dialogues for a back-and-forth dialog.

Usually, you may consider ChatGPT as an app and GPT because the brains behind the app.

OpenAI launched an API to allow builders so as to add GPT-based options to apps and even create new apps primarily based on the mannequin’s options. This, in flip, helps them retrain their mannequin and enhance the standard of the generated textual content outputs.

Now that you simply’ve discovered these fundamental ideas about AI and language fashions, it’s time so as to add GPT-based options to Wizz, a trivia recreation that solely wizards (pun meant) can beat!

Acquiring an OpenAI API Key

So as to add AI to your app, you’ll use OpenAI’s API. For this, you’ll want an account. You may create a brand new one or use your individual.

Observe: If you have already got an account and wish to use it for this tutorial, remember the fact that your credit score might have expired already. In that case, you’ll want a brand new account or so as to add billing info and improve to a paid account.

OpenAI's home page after authentication

Now, click on in your profile, once more situated within the prime proper nook of the display screen. It ought to show a pop-up menu like the next:

Profile popup menu

Then, choose View API keys. Subsequent, press Create new secret key. You may select a reputation for the important thing (it’s non-obligatory) and click on Create secret key. This may create your secret key.

Be sure that to repeat the important thing someplace protected since you received’t be capable of view it once more. You’ll want so as to add this key to the challenge afterward.

Nice job, you’ve created an account and have entry to OpenAI’s API platform. This can be a small step to your app however an enormous leap to your improvement expertise.

Studying Finest Practices for GPT Fashions

Now that you simply’ve taken step one in the direction of implementing AI in your apps, it’s time to debate finest practices when interacting with GPT fashions through API or the ChatGPT app.

Though GPT fashions do an incredible job of attempting to grasp what you imply, they won’t all the time work as anticipated since it could’t learn your thoughts (but!).

That is the place finest practices round prompting are available in. They’ll enable you to get higher outcomes from the language mannequin.

Listed here are some methods which may enhance your outcomes when utilizing GPT fashions. Every of them additionally has examples which you can mess around with in OpenAI’s Playground:

You’ll present questions for the sport and provides hints to the gamers.

When offering questions, you’ll add humor to the query within the type of a enjoyable reality.

When giving enjoyable details, you must add puns to make it enjoyable.

These situations are an incredible instance of when to make it simpler on the mannequin by breaking them down step-by-step. For instance, when producing trivia questions, you may want the mannequin to observe sure steps. Right here’s the information you’ll use when prompting the mannequin for brand spanking new trivia questions:

To resolve this, do the next:
– First, you’ll randomly choose one of many following subjects: historical past, arts, leisure, sports activities, science, or geography.
– Then, you’ll generate a query primarily based on the subject chosen.

To resolve this, do the next:
– First, you’ll analyze the query and decide the proper reply.
– Then, you’ll generate a touch that’ll make it simpler to reply. Be sure that the trace shouldn’t be too apparent.

Don’t resolve on the trace till you’ve answered the query your self.

  • Use persona to offer context: Typically, the reply you get won’t be what you wished when it comes to area or technical depth. In these circumstances, it is likely to be a good suggestion to offer a persona definition that will help you get the reply you might be on the lookout for. For instance, right here’s the persona that you simply’ll use to make sure that the mannequin is aware of what type of responses you expect:

    You’re the know-it-all and humorous host of a trivia recreation referred to as Wizz.

  • Give step-by-step guides to finish a job: Some duties may be advanced sufficient that the mannequin can have problem understanding them.

    Your job is to generate a brand new trivia query for the participant.

  • Present output examples: If you would like the mannequin to repeat a specific type or observe a sure format when responding. Then it’s a good suggestion to supply examples.

This can be a widespread state of affairs when validating solutions from an issue assertion given by different customers. A very good use case in Wizz is when asking for hints, you’ll first need the mannequin to grasp the query earlier than giving a touch so that you simply keep away from apparent hints.
