unreachable_from_main
Unreachable top-level members in executable libraries.
Details
#Any member declared in an executable library should be used directly inside that library. An executable library is a library that contains a main
top-level function or that contains a top-level function annotated with @pragma('vm:entry-point')
). Executable libraries are not usually imported and it's better to avoid defining unused members.
This rule assumes that an executable library isn't imported by other libraries except to execute its main
function.
BAD:
main() {}
void f() {}
GOOD:
main() {
f();
}
void f() {}
Enable
#To enable the unreachable_from_main
rule, add unreachable_from_main
under linter > rules in your analysis_options.yaml
file:
linter:
rules:
- unreachable_from_main
If you're instead using the YAML map syntax to configure linter rules, add unreachable_from_main: true
under linter > rules:
linter:
rules:
unreachable_from_main: true
