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):
Future<Null> f() async {}
Common fixes
#Replace the use of Null
with a use of void
:
Future<void> f() async {}
