Flutter: Filter list as per some condition

Question

I\'m having list of Movies. That contains all Animated & non Animated Movies. To identify whether its Animated or not there is one flag called as isAnimated

Answer 1

where function on a List returns Iterable. You have to convert it to List using the function List.from(Iterable).

So in the above scenario you should use the following code snippet.

Iterable _AnimatedMoviesIterable = AllMovies.where((i) => i.isAnimated);

_AnimatedMovies = List.from(_AnimatedMoviesIterable);

Answer 2

You can use toList() method to get your desire output like following

toList() Collects all elements of this stream in a List.

To fix the above issue:

Add a toList() (This code creates a List<dynamic>)

_AnimatedMovies = AllMovies.where((i) => i.isAnimated).toList();

instead of

_AnimatedMovies = AllMovies.where((i) => i.isAnimated);

Answer 3

toList() is missing to materializer the result

_AnimatedMovies = AllMovies.where((i) => i.isAnimated).toList();
