return_without_value
The return value is missing after 'return'.
Description
#The analyzer produces this diagnostic when it finds a return
statement without an expression in a function that declares a return type.
Example
#The following code produces this diagnostic because the function f
is expected to return an int
, but no value is being returned:
dart
int f() {
return;
}
Common fixes
#Add an expression that computes the value to be returned:
dart
int f() {
return 0;
}
