unnecessary_unawaited
Unnecessary use of 'unawaited'.
Description
#The analyzer produces this diagnostic when unawaited
is used to mark a
call to a function, method, or operator, or a reference to a field,
getter, or top-level variable as safely not being awaited, but the called
member is also annotated with @awaitNotRequired
. This annotation itself
signals that wrapping with unawaited
is unnecessary at any call site.
Example
#The following code produces this diagnostic because unawaited
is invoked
on a call to a function that's annotated with @awaitNotRequired
:
dart
import 'dart:async';
import 'package:meta/meta.dart';
@awaitNotRequired
Future<bool> log(String message) async => true;
void f() {
unawaited(log('Message.'));
}
Common fixes
#Remove the invocation of unawaited
:
dart
import 'package:meta/meta.dart';
@awaitNotRequired
Future<bool> log(String message) async => true;
void f() {
log('Message.');
}
