MinValidator<T extends num> class

A validator that ensures a given num value meets a specified minimum limit.

The MinValidator checks if the provided value is greater than or equal to min. If the value is within the allowed range, validation passes (null is returned). Otherwise, it returns the provided error message.

Example

final validator = MinValidator(10, message: 'Value must be at least 10');

print(validator.validate(15));  // null (valid)
print(validator.validate(10));  // null (valid)
print(validator.validate(9));   // 'Value must be at least 10' (invalid)
print(validator.validate(null)); // 'Value must be at least 10' (invalid)
