implicit_call_tearoffs
Implicit tear-off of the 'call' method.
Description
#The analyzer produces this diagnostic when an object with a call
method is assigned to a function-typed variable, implicitly tearing off the call
method.
Example
#The following code produces this diagnostic because an instance of Callable
is passed to a function expecting a Function
:
dart
class Callable {
void call() {}
}
void callIt(void Function() f) {
f();
}
void f() {
callIt(Callable());
}
Common fixes
#Explicitly tear off the call
method:
dart
class Callable {
void call() {}
}
void callIt(void Function() f) {
f();
}
void f() {
callIt(Callable().call);
}
