prefer_void_to_null
Unnecessary use of the type 'Null'.
Description
#The analyzer produces this diagnostic when Null
is used in a location
where void
would be a valid choice.
Example
#The following code produces this diagnostic because the function f
is
declared to return null
(at some future time):
dart
Future<Null> f() async {}
Common fixes
#Replace the use of Null
with a use of void
:
dart
Future<void> f() async {}
