Welcome to this guide where we will explore how to seamlessly integrate your Flutter application with Google Sheets using Google AppScript. Whether you’re collecting user feedback or managing data, this method offers a simple and efficient solution.

What You Will Learn

• How to set up both Flutter and Google Sheets
• How to implement Google AppScript for data handling
• How to send and retrieve data using HTTP requests

Getting Started

Google Sheets is an incredible tool that offers a robust interface using Google AppScript. This allows you to perform various operations like reading, inserting, updating, and deleting data. With this powerful capability, you can even use Google Sheets as the backend for your application!

In this tutorial, we will develop a sample Flutter application that collects user feedback and stores it in Google Sheets through Google AppScript. Following that, we will fetch the feedback responses back into the Flutter app for display.

Setting Up Your Flutter Application

Before we dive into the code, let’s ensure everything is set up properly:

• Follow this lab to write your first Flutter app.
• Check out the Cookbook for useful Flutter samples.
• For comprehensive documentation, refer to Flutter’s online documentation.

The Code Behind It

Imagine you have a suggestion box in a restaurant. Customers drop their feedback in the box (Flutter app), which a server staff collects at the end of the day and summarizes it in a notebook (Google Sheets). Similarly, when the submit button in your Flutter app is pressed, an HTTP POST request is triggered to the Google AppScript URL. The AppScript retrieves the submitted data and logs it into Google Sheets. Conversely, a GET request can be sent to fetch the stored feedback and display it in your app.

// Sample Google Apps Script to handle requests
function doPost(e) {
    var sheet = SpreadsheetApp.openById("Your-Spreadsheet-ID").getActiveSheet();
    var data = JSON.parse(e.postData.contents);
    sheet.appendRow([data.name, data.feedback]); // Store feedback
    return ContentService.createTextOutput("Feedback stored successfully");
}

function doGet() {
    var sheet = SpreadsheetApp.openById("Your-Spreadsheet-ID").getActiveSheet();
    var data = sheet.getDataRange().getValues();
    return ContentService.createTextOutput(JSON.stringify(data)); // Fetch feedback
}

Running the App

You can now run the application by clicking here! As you can see in the examples above, when the Submit Feedback button is clicked, the feedback is stored in Google Sheets. The results can be displayed in the app itself!

Troubleshooting

If you run into issues, here are some common pitfalls:

• Ensure your Google AppScript is correctly deployed as a Web App with permissions set to allow anyone to access it.
• Check the Spreadsheet ID in the script and ensure it matches your Google Sheets document.
• If data isn’t displaying, confirm that the HTTP requests are being sent correctly from your Flutter app.
