tearDown function Null safety

void tearDown(
  1. dynamic body(

    Registers a function to be run after tests.

    This function will be called after each test is run. The body may be asynchronous; if so, it must return a Future.

    If this is called within a test group, it applies only to tests in that group. The body will be run before any tear-down callbacks in parent groups or at the top level.

    Each callback at the top level or in a given group will be run in the reverse of the order they were declared.

    See also addTearDown, which adds tear-downs to a running test.
