Error accessing properties in StatefulWidget

Issue

I'm new to flutter. I'm accessing a property-"startingProduct" in a State Class. The variable was defined in A StatefulWidget Class. But I get "startingProduct is not defined". How do I fix the code?

final String startingProduct; // `StatefulWidget` class

ProductManager(this.startingProduct); // `StatefulWidget` class

_products.add(widget.startingProduct); // `State` class

Error: The getter 'startingProduct' isn't defined for the class 'StatefulWidget'.

Solution

In this case, you most likely forgot to specify the type of the State class.

You should use the following syntax:

class _ExampleState extends State<Example> { // in this case `Example` is your StatefulWidget class

To be more clear: I mean that you need to specify the optional type argument T as your StatefulWidget class, e.g. extends State<Example> instead of extends State.
