What is the difference among .cast() and List.from() and List.castFrom()

Issue

List foo -> List bar
I can use three method

1.List<MyClass> bar = foo.cast<MyClass>()
2.List<MyClass> bar = List.castFrom(foo)
3.List<MyClass> bar = List.from(foo)

What is the difference?

Solution

  1. cast<MyClass>: Returns the view (Immutable List, altering order of the list won’t be reflected in original list) of the List containing instances of MyClass type. Please follow.
  2. castFrom(foo): Adapts source (foo) to be a List. Please follow
  3. from(foo): Creates a List from Iterable (foo) objects provided in the Argument. Please follow
