Leveraging Firebase Extensions

Firebase Extensions provide developers with pre-built solutions, eliminating the need for extensive research or coding. In this project, we leverage the Multimodal Tasks with the Gemini API to generate content using both text and image inputs.

Multimodal Tasks with Gemini API Firebase Extension:

This extension facilitates multimodal generative tasks by integrating text and image processing. Utilizing Gemini models and Firestore, it offers customizability through prompt engineering for diverse content creation.

Installing the Extension

To integrate the extension into your project, follow these steps:

Option 1: Using the Firebase CLI

Install the extension through the Firebase CLI with the following command:

firebase ext:install googlecloud/firestore-multimodal-genai --project=projectId

Ensure to replace projectId with your actual Firebase project ID.

Option 2: Using the Firebase Console

Visit the extension homepage.
Click on “Install in Firebase Console”.

Choose the method that suits your workflow best to seamlessly integrate the extension into your Firebase project.

Configuring the Extension

When setting up the “Multimodal Tasks with the Gemini API” Firebase extension, you’ll come across various configuration parameters crucial for customizing the extension to suit your requirements. Understanding these parameters and setting them effectively is essential for optimizing the capabilities of the Gemini API in your Flutter applications. Below, we elaborate on each parameter and offer examples for clarity.

Configuring Parameters for Gemini API Integration

When setting up the “Multimodal Tasks with the Gemini API” extension, it’s crucial to configure various parameters to tailor the integration to your specific needs. Here’s a breakdown of each parameter and its significance:

Gemini API Provider Selection:

Choose between Google AI and Vertex AI, each offering distinct functionalities suited to different development needs.

Gemini Model:

Select the specific Gemini model you wish to utilize, such as Gemini Pro or Gemini Pro Vision. Models vary by provider and can be found in the documentation for Vertex AI and Google AI.

Google AI API Key:

Required for Google AI provider authentication. This key authenticates your requests. Vertex AI users utilize application default credentials instead.

Firestore Collection Path:

Specifies the Firestore collection path where the extension should listen for new documents to process. This path directs the Gemini API to perform tasks based on the document data.

Prompt:

A structured text template guiding the Gemini API on understanding and generating responses based on the input. It may include placeholders for dynamic content extracted from Firestore documents.
Example: “Please generate a summary for the following article: {{articleContent}}”

Variable Fields:

List document fields to use as variables in the prompt, separated by commas.
Example: “articleContent, image”

Image Field (Gemini Pro Vision):

For image-related tasks, specify a field containing an image’s Cloud Storage URL or a base64 image string. Exclusive to the Gemini Pro Vision model.

Response Field:

Specifies the document field where the API’s response will be stored.

Cloud Functions Location:

Select the geographical location for deploying the extension’s Cloud Functions, guided by Google’s location selection advice.

Configuring these parameters effectively ensures the seamless integration and optimal performance of the Gemini API in your Flutter applications.

How It Works: Streamlining Generative Tasks with Gemini API Extension

The integration of the Gemini API extension for Firebase and Firestore simplifies generative tasks by merging custom prompts with the powerful Gemini API and Firestore’s data management capabilities. Here’s a simplified overview of the workflow:

Setup:

Configure the extension within Firebase, establishing a connection between the Gemini API and Firestore for seamless data interaction.

Data Capture and Storage:

Input data, including text, images, or a combination, is captured and stored in Firestore, ready for processing.

Custom Prompts:

Users create custom prompts tailored to guide the Gemini API in generating the desired output for the task at hand.

API Interaction:

The extension transmits these prompts to the Gemini API, along with relevant input data from Firestore, initiating the generative process.

Generative Task Processing:

Utilizing advanced AI models, the Gemini API processes the prompts and inputs to generate outputs, which could be text, images, or a combination thereof, depending on the task’s requirements.

Output Management:

The generated content is then saved back into Firestore, where it can be accessed for further use, such as in applications or for content display.

Let’s Build the Worksheet Generator Flutter App

The Worksheet Generator Flutter App integrates Firebase AI Extensions to provide users with a streamlined platform for creating customized math worksheets. Here’s a step-by-step guide to building this app:

Step 1: Initialize Firebase

Set up Firebase by providing the default Firebase options, including the API key, authentication domain, project ID, storage bucket, messaging sender ID, and app ID.

Step 2: Create the UI for User Input as Text

Implement a TextField widget where users can input their desired worksheet parameters. Customize the widget to allow multiline input and adjust the number of lines accordingly.

Step 3: Save the Input to Firestore

Utilize a TextButton to trigger an action when clicked. Verify if the text input is empty, and if not, add the text to Firestore as a new document. Update the UI by assigning the document ID of the newly created document.

Step 4: Create the UI for User Input as Image

Implement an IconButton to allow users to upload an image. Upon pressing the button, asynchronously retrieve an image using ImagePickerWeb and store it. Update the UI accordingly and call the uploadImage function.

Step 5: Upload the Image to Cloud Storage and Save it to Firestore

Prepare the image for upload by generating a unique file name and obtaining a reference to the location in Cloud Storage. Upload the image using the putData method and wait for the task to complete. Store the image URL and any additional data to Firestore, updating the UI state with the document ID for reference.

Step 6: Retrieve the Result from Firestore and Display it in the App

Define a UI widget using a Container with specific dimensions and decoration. Use the _buildContent method to display the content retrieved from Firestore. Implement data fetching using StreamBuilder to listen to changes on a Firestore document. Handle waiting for data and errors, and display the content accordingly.

Data Display

Build the UI to display the content retrieved from Firestore, including an IconButton to copy data to the clipboard and a Text widget to display the data. Implement a placeholder to display when no document ID is available.

By following these steps, you can create a Worksheet Generator Flutter App that leverages Firebase AI Extensions to provide users with personalized math worksheets tailored to their specifications.
