Validart class

The Validart class is the entry point for defining validation rules.

It provides a fluent API for validating different data types, including:

  • Strings (VString)
  • Booleans (VBool)
  • Integers (VInt)
  • Doubles (VDouble)
  • Numeric values (VNum)
  • Maps (VMap)
  • Date (VDate)

This class enables custom validation rules and supports chaining for complex validation logic.

Example

final v = Validart();

final validator = v.string().min(5).max(20);

print(validator.validate('Hello')); // true
print(validator.validate('Hi')); // false (too short)
