How can I make real-time screen-related API calls when a screen is opened in Flutter?

How can I efficiently make real-time API calls related to a screen when the screen is opened in a Flutter application, ensuring up-to-date data is always displayed?

To efficiently make real-time API calls when a screen is opened in a Flutter application, you can use the initState method of a StatefulWidget to trigger the API call when the screen is initialized. Additionally, you can use the FutureBuilder widget to handle the asynchronous nature of the API call and update the UI accordingly. Here's a step-by-step guide:

Create a StatefulWidget: Define a stateful widget for your screen.

Use initState: Override the initState method to trigger the API call when the screen is initialized.

Use FutureBuilder: Use the FutureBuilder widget to handle the API call and update the UI based on the result.
