Passing data to StatefulWidget and accessing it in its state in Flutter

📝 How to Pass Data to StatefulWidget and Access it in the State in Flutter 📱

Are you struggling with passing data to a StatefulWidget and accessing it in its state in your Flutter app? 🤔

Well, fret not! In this blog post, we will address this common issue and provide you with easy solutions. Let's dive right in! 💪

🔸 Understanding the Problem

Imagine you have two screens in your Flutter app: a list of records and a screen for creating and editing records. If you pass an object to the second screen, it indicates that you want to edit the existing record. On the other hand, passing null means you are creating a new item 📝.

However, you're facing a challenge when it comes to using the approach mentioned in the official Flutter cookbook for your specific case. ♨️

🔸 Solving the Problem

To access the recordObject inside the _RecordPageState (the state of the RecordPage), follow these simple steps:

1. Declare the recordObject as a parameter in the RecordPage constructor. This will allow you to pass the object when navigating to the second screen.

class RecordPage extends StatefulWidget {
  final Record recordObject;

  RecordPage({Key key, @required this.recordObject}) : super(key: key);

  @override
  _RecordPageState createState() => new _RecordPageState();
}

1. Inside the _RecordPageState, you can access the recordObject through the widget property, which represents the current instance of the RecordPage widget.

class _RecordPageState extends State<RecordPage> {
  @override
  Widget build(BuildContext context) {
    // Accessing the recordObject
    Record record = widget.recordObject;

    // Continue building the UI for the record page
    // .....
  }
}

That's it! You can now access the recordObject inside the _RecordPageState of your RecordPage.
