return_of_do_not_store
'{0}' is annotated with 'doNotStore' and shouldn't be returned unless '{1}' is also annotated.
Description
#The analyzer produces this diagnostic when a value that is annotated with the doNotStore
annotation is returned from a method, getter, or function that doesn't have the same annotation.
Example
#The following code produces this diagnostic because the result of invoking f
shouldn't be stored, but the function g
isn't annotated to preserve that semantic:
import 'package:meta/meta.dart';
@doNotStore
int f() => 0;
int g() => f();
Common fixes
#If the value that shouldn't be stored is the correct value to return, then mark the function with the doNotStore
annotation:
import 'package:meta/meta.dart';
@doNotStore
int f() => 0;
@doNotStore
int g() => f();
Otherwise, return a different value from the function:
import 'package:meta/meta.dart';
@doNotStore
int f() => 0;
int g() => 0;
