tearDown method Null safety

  1. @override
Future<void> tearDown(
  1. TargetPlatform value,
  2. covariant TargetPlatform? memento
)
override

A function that is guaranteed to be called after a value is tested, even if it throws an exception.

Calling this function must return the testing environment back to the base state it was in before setUp was called. The memento is the object returned from setUp when it was called.

Implementation

@override
Future<void> tearDown(TargetPlatform value, TargetPlatform? memento) async {
  debugDefaultTargetPlatformOverride = memento;
}
