Step-by-Step Guide on Integrating FlutterFlow with Google Cloud AI Platform
Integrating FlutterFlow with Google Cloud AI Platform enables you to leverage powerful machine learning models in your mobile applications. This guide will walk you through all the necessary steps to achieve this integration.
Prerequisites
- Ensure you have a Google Cloud Platform (GCP) account.
- Set up billing on your GCP account.
- Install the Flutter SDK and FlutterFlow on your local machine.
- Basic knowledge of Google Cloud AI Platform and FlutterFlow.
Step 1: Set Up Google Cloud AI Platform
Create a New Project
- Go to the Google Cloud Console.
- Click on the project dropdown and select "New Project."
- Enter a name for your project and click "Create."
Enable the required APIs
- Navigate to "APIs & Services" > "Library."
- Enable the following APIs:
- AI Platform Training & Prediction API
- Cloud Storage API
Create a Service Account
- Go to "IAM & Admin" > "Service Accounts."
- Click "Create Service Account."
- Provide a name and ID for the service account.
- Assign roles:
- AI Platform Admin
- Storage Admin
- Click "Done" to finish the setup.
Generate Service Account Key
- Click on the created service account.
- Navigate to the "Keys" tab and click "Add Key" > "Create New Key."
- Select "JSON" as the key type and download the JSON file. Store this file securely, as you'll need it later.
Step 2: Train and Deploy Your Model
Train Your Machine Learning Model
- Prepare your dataset and model script.
- Use Google Cloud AI Platform to train your model by uploading your data to a Cloud Storage bucket and running a training job.
- You can use the Google Cloud SDK or the AI Platform console to submit a training job.
Deploy the Model
- Once your model training is complete, deploy it to the AI Platform as a model endpoint:
- Go to "AI Platform" > "Models."
- Click "Create Model" and provide necessary details.
- Click on the model and select "Create Version."
- Specify the Cloud Storage path to your trained model and deploy it.
Step 3: Prepare FlutterFlow for Integration
Create a New FlutterFlow Project
- Sign in to FlutterFlow and create a new project.
- Configure the project settings such as project name, API key, etc.
Set Up HTTP Requests
- Navigate to the "API Calls" section in the FlutterFlow project.
- Click "Add API Call" to configure the endpoint for calling your deployed model.
Step 4: Configure API Call in FlutterFlow
Define the API Endpoint
- In the "Add API Call" dialog:
- Type: Select "POST".
- Endpoint: Enter the endpoint URL of your deployed AI model. The URL typically follows this format: `https://-ml.googleapis.com/v1/projects//models/:predict`
- Request Header:
- Key: `Authorization`
- Value: `Bearer `. You might use the service account key to generate this access token dynamically if needed.
- Body: Define the JSON body as required by your AI model. This usually includes the input features for your model.
Add Inputs and Outputs
- Define the necessary inputs (parameters) the model will need.
- Specify the expected outputs (response fields) from the AI model.
Step 5: Generate Access Token
Using Service Account Key
Step 6: Integrate the API Call into Your FlutterFlow App
Design Your UI
- Use FlutterFlow's drag-and-drop interface to design the screens and components that will interact with the AI model.
Trigger the API Call
- Add an action to the appropriate widget (e.g., button, form submission).
- Choose "Call API" and select the API call configured in the previous steps.
- Map the input fields from your UI to the API call inputs.
- Handle the API response to update the UI or take necessary actions based on the model's prediction.
Step 7: Test Your Integration
- Run your FlutterFlow app in debug mode.
- Interact with the UI to trigger the API call.
- Check the responses from Google Cloud AI Platform and ensure the integration works as expected.
By following these steps, you can successfully integrate FlutterFlow with Google Cloud AI Platform, enabling your mobile app to leverage powerful machine learning models.
