Question

I\'m trying to access a class value by using a variable previously defined in dart, but I keep getting the error the operator [] isn\'t defined for the class

You can createn a toMap() function in your Movie class and access properties using [] operator

class Movie {
  String name;
  String actor;
  String producer;

  Map toMap() {
    return {
      'name': name,
      'actor' : actor,
      'producer' : producer,
    };
  }
}

Now Movie class properties can be accessed as:

Movie movie = Movie();
movie.toMap()['name'];
