Blank()Validates if the given input is a blank value (null, zeros, empty strings or empty arrays, recursively).
We recommend you to check Comparing empty values for more details.
v::blank()->assert(' ');
// Validation passes successfully
v::blank()->assert(0);
// Validation passes successfully
v::blank()->assert(false);
// Validation passes successfully
v::blank()->assert(['', ' ', '0.0', []]);
// Validation passes successfully
v::blank()->assert(new stdClass());
// Validation passes successfully
It's similar to Falsy, but way stricter.
