avoid_function_literals_in_foreach_calls
Function literals shouldn't be passed to 'forEach'.
Description
#The analyzer produces this diagnostic when the argument to Iterable.forEach
is a closure.
Example
#The following code produces this diagnostic because the argument to the invocation of forEach
is a closure:
void f(Iterable<String> s) {
s.forEach((e) => print(e));
}
Common fixes
#If the closure can be replaced by a tear-off, then replace the closure:
void f(Iterable<String> s) {
s.forEach(print);
}
If the closure can't be replaced by a tear-off, then use a for
loop to iterate over the elements:
void f(Iterable<String> s) {
for (var e in s) {
print(e);
}
}
