How The instance member ‘x’ can’t be accessed in an initializer Error Occurs ?

I have one class and whenever that class build I want to initialized the object. Here is my code. And I am using GetX.

class ProductReview extends GetxController {
  Map<String, String> productReviews = Get.reviews;

  var avg_rating = productReviews.[avg_rating];
}

But this code give me following error.

Error report--"The instance member 'productReviews' can't be accessed in an initializer." I am new to programming and this is being called directly from a widget. I checked the LevelUp map and it has contents. The error occurs where I am trying to assign the param value to avg_rating. It doesn't matter if I put the key in quotes or provide an integer. Any advice would be greatly appreciated.

Solution 1

Here we can’t direct assign productReviews before Class initialized the object. To fix you just move avg_rating initialization into a constructor. Here is how you can do.

class ProductReview extends GetxController {
  Map<String, String> productReviews = Get.reviews;
  String avg_rating;
  
  ProductReview() {
    avg_rating = productReviews[avg_rating];
  }
}
