avoid-unnecessary-type-casts

added in: 1.6.0

Warns about of unnecessary use of casting operators.

Example

class Example {
final myList = <int>[1, 2, 3];

void main() {
final result = myList as List<int>; // LINT
}
}

class Animal {}

class HomeAnimal extends Animal {}

void patterns() {
final animal = Animal();

if (animal case Animal() as HomeAnimal) {}
if (animal case Animal() as Animal) {} // LINT
}
