always_put_control_body_on_new_line

Statement should be on a separate line.

The analyzer produces this diagnostic when the code being controlled by a control flow statement (if, for, while, or do) is on the same line as the control flow statement.

The following code produces this diagnostic because the return statement is on the same line as the if that controls whether the return will be executed:

void f(bool b) {
  if (b) return;
}

Put the controlled statement onto a separate, indented, line:

void f(bool b) {
  if (b)
    return;
}
