void_checks

Learn about the void_checks linter rule.

Core

Don't assign to void.

DON'T assign to void.

BAD:

dart

class A<T> {
  T value;
  void test(T arg) { }
}

void main() {
  A<void> a = A<void>();
  a.value = 1; // LINT
  a.test(1); // LINT
}

To enable the void_checks rule, add void_checks under linter > rules in your analysis_options.yaml file:

analysis_options.yaml

yaml

linter:
  rules:
    - void_checks

If you're instead using the YAML map syntax to configure linter rules, add void_checks: true under linter > rules:

analysis_options.yaml

yaml

linter:
  rules:
    void_checks: true
