Warns when a return statement is unnecessary and can be removed.

Example​

❌ Bad:

const _value = 1;

void someFunction() {
  if (_value == 2) {
    ...

    return; // LINT: Unnecessary return statement. Try removing it.
  } else {
    ...
  }
}

void another() {
  if (_value == 2) {
    ...

    return; // LINT: Unnecessary return statement. Try removing it.
  }
}

void anotherOne() {
  ...

  return; // LINT: Unnecessary return statement. Try removing it.
}

✅ Good:

const _value = 1;

void someFunction() {
  if (_value == 2) {
    ...
  } else {
    ...
  }
}

void another() {
  if (_value == 2) {
    ...
  }
}

void anotherOne() {
  ...
}
