Flutterflow

Creating a Latenode Scenario

• Trigger on Webhook: Start the scenario with this node and save its URL for later use in Flutterflow.

• JavaScript: Add a node with code to generate a random number.

export default async function run({execution_id, input, data, store}) {
    let randomNumber = Math.floor(Math.random() * 101);

    return {
        random_number: randomNumber
    }
}

• Webhook Response: Use this node to send the scenario's result to Flutterflow.

Building the Form in Flutterflow

Create Project

• Go to the Projects page and click Create new.

• Name the new project and select Create Blank.

Interface Design

• In the Widget Tree (1) tab, view interface elements and update the text element (2) at the top.

• Add a TextField (2) to the Column (1) element.

• Add a Button to the Column.

• Customize settings, align fields, and rename buttons as desired.

API Setup

• In the API Calls (1) tab, select Create API Call (2).

• Name the call (1), add the Trigger on Webhook (2) node address, and click Add Call (3).

Testing

• Run once the scenario on Latenode.

• In the Response & Test tab, click "Test API Call" and view the results. For the output parameter number, click Add JSON Path, name it (1), and save (2).

• Return to the Widget Tree (1) tab and click Add parameter (2).

• Add a string parameter number and click Confirm.

• For the TextField (1) element, set the Initial Value (2) to the number (3).

• For the Button (1) element, go to the Action section (2).

• Open the Action Flow Editor and add an action to call the configured API, so the request is sent to Latenode when the button is clicked. Change the output parameter name of the first action as needed.

• Add an action to pass the response to the number parameter.

Testing the Created Scenario and Flutterflow Form

• Click the application launch button.

• Run once the scenario on the Latenode platform.
