completion function Null safety
- dynamic matcher,
- [@Deprecated('this parameter is ignored') String? description]
Matches a Future that completes successfully with a value that matches
matcher
.
This creates an asynchronous expectation. The call to expect will return
immediately and execution will continue. Later, when the future completes,
the expectation against matcher
will run. To wait for the future to
complete and the expectation to run use expectLater and wait on the
returned future.
To test that a Future completes with an exception, you can use throws and throwsA.
Implementation
Matcher completion(matcher,

_Completes(wrapMatcher(matcher));
