Connect to FlutterFlow: List and Single-Item View

In this tutorial, we'll learn how to connect Xano, a no-code backend platform, with Flutter Flow, a powerful front-end builder. We'll explore how to make API calls from Flutter Flow to Xano, display data from Xano in a list view, and create a single page view for each item in the list. Let's dive in!

Prerequisites

Before we begin, ensure you have the following:

• A Xano account (sign up for free at https://xano.io)
• A Flutter Flow account (sign up for free at https://flutterflow.io)
• A basic understanding of Flutter Flow's UI builder

Step 1: Set Up Your Xano API

1. Log in to your Xano workspace and create a new database with a table called "Places." This table should have fields for id (integer), name (text), location (text), and image (object with a nested url field).
2. Add some sample data to the "Places" table, including a few different locations with names, locations, and image URLs.
3. In the Xano API section, locate the endpoint for the "Places" table (e.g., /api/places). This endpoint will return a list of all the places in your database.
4. Also, note the endpoint for fetching a single place record (e.g., /api/places/{id}). This endpoint takes an id parameter to retrieve a specific place.

Step 2: Connect Xano to Flutter Flow

1. Open your Flutter Flow project and navigate to the "API Calls" section on the left sidebar.
2. Click "Add API Call" and give it a name (e.g., "Get Places").
3. Paste the endpoint URL from Xano for fetching the list of places (e.g., /api/places).
4. Click "Test API Call" to ensure the connection is successful.
5. In the "Response" section, select the JSON fields you want to display in your app (e.g., id, name, location, and image.url).
6. Repeat steps 2-5 to create another API call for fetching a single place record (e.g., "Get Single Place"). Replace the {id} portion of the endpoint URL with [id] and define the id variable in the "Variables" section.

Step 3: Display the List of Places

1. In the Flutter Flow UI builder, add a ListView component to your homepage.
2. Inside the ListView, add a Card component with an Image and Text widgets for displaying the place's image, name, and location.
3. Select the ListView and navigate to the "Backend Query" section on the right sidebar.
4. Choose the "Get Places" API call from the dropdown menu.
5. Enable "Generate Dynamic Children" and specify the variable name (e.g., listOfPlaces).
6. In the Image widget, set the path property to listOfPlaces.item.image.url to display the image URL from Xano.
7. In the Text widgets, set the text value to listOfPlaces.item.name and listOfPlaces.item.location to display the place's name and location.

Step 4: Create a Single Page View

1. In Flutter Flow, create a new page for displaying the single place view (e.g., "Single View").
2. On the new page, select the entire page and navigate to the "Backend Query" section on the right sidebar.
3. Choose the "Get Single Place" API call from the dropdown menu.
4. Under "Additional Variables," set the id parameter value to listOfPlaces.item.id. This will pass the id of the selected place from the list view to the single view page.
5. Add an Image widget and set its path property to image.url to display the place's image.
6. Add Text widgets for the place's name and location, setting their text values accordingly.

Step 5: Navigate to the Single Page View

1. In the list view, select one of the Card components representing a place.
2. In the "Action Flow Editor" on the right sidebar, add an "On Tap" action.
3. Choose "Navigate to Single View" and specify the id parameter name (e.g., placeId).
4. Under "Parameters," select "Pass" and set the value to listOfPlaces.item.id. This will pass the selected place's id to the single view page.

Step 6: Test Your App

1. In Flutter Flow, click the "Run App in Test Mode" button to launch the app in a simulated environment.
2. Verify that the list of places from Xano is displayed correctly on the homepage.
3. Tap on one of the places in the list to navigate to the single view page, ensuring the correct place's details are shown.

Congratulations! You've successfully connected Xano with Flutter Flow, displaying data from your Xano backend in a Flutter Flow app. This integration empowers you to build powerful applications without writing complex backend code, leveraging the strengths of both Xano and Flutter Flow.
