return_ without_ value
Details about the 'return_without_value' diagnostic produced by the Dart analyzer.
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:
int f() {
return;
}
Common fixes
#Add an expression that computes the value to be returned:
int f() {
return 0;
}
