MovieList | keeps track of the movies and TV series | REST library

If the Movie object needs to be shared between Actors, another way to do this is to use std::vector> instead of std::vector or std::vector.

The reason why std::vector would be difficult is basically what you've discovered. The Movie object is separate from another Movie object, even if the Movie has the same name.

Then the reason why std::vector would be a problem is that yes, you can now "share" Movie objects, but the maintenance of keeping track of the number of shared Movie objects becomes cumbersome.

In comes std::vector> to help out. The std::shared_ptr is not just a pointer, but a smart pointer, meaning that it will be a reference-counted pointer that will destroy itself when all references to the object go out of scope. Thus no memory leaks, unlike if you used a raw Movie* and mismanaged it in some way.

You should use adapter.observe{} function. Inside observe you can put notify data changed.

You can fine more information about this in

Inside the map function you need to return the

element.

Since pageOneData is initially an empty object, pageOneData.contentItems will be undefined in the first render cycle. causing movieList.map to fail as your useEffect call is made after the initial render and that fires an API which again is async and will take time to fetch the result

You can use default value for movieList to solve the error

1. First of all, you should add "require" in your class. Otherwise dart will give you a similar error like the next one:

line 51 • The parameter 'movieName' can't have a value of 'null' because of its type, but the implicit default value is 'null'. (view docs) Try adding either an explicit non-'null' default value or the 'required' modifier.

1. Import the class and the example information where you need it.

   import 'package:exampleapp/movie_list_sample_information.dart;

   import 'package:exampleapp/movies.dart;

2. Use the variable to get the information

   movieLists[0].movieName // gets the first movie of your list

The next dartpad uses your code as example: https://dartpad.dev/95d67aa68267296ac3fd8a56405b2880?null_safety=true

Press "Run" button and you should see the name of the first movie in "Console"

EDIT:

To read the list in dynamically in flutter you can use ListView.builder

Your service returns object with movies array and additional info like "totalResults", you need to get movies array by taking "Search" field from your response object. So just change

Generally it sounds like you are trying to have the appearance of a sorted array, but need to preserve the initial configuration. There are more than a few ways to achieve this behaviour.

Probably the easiest is to sort a copy of the list and pass that to the MovieList component. Determine if the list should be sorted or not based on button press by keeping track of a boolean value in State.

You need to place state object in CustomTabView, like
