Don't assign to void.

This rule is available as of Dart 2.0.0.

Rule sets: core, recommended, flutter

DON'T assign to void.

BAD:

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:
