Numbers, booleans, and dates
Choose a primitive schema and add the constraints your data needs.
Numeric values
Acanthis provides three types to represent numeric values: AcanthisNumber, AcanthisInt and AcanthisDouble. They share the same fluent checks.
Use the number() function or the integer() or doubleType() functions to create a number schema. This method allows you to validate and transform numbers.
dart
number().gt(5);
number().gte(10);
number().lt(5);
number().lte(10);
number().positive();
number().negative();
number().nonNegative();
number().nonPositive();
number().multipleOf(5);
number().integer();
number().double();
number().nonNan();
number().nan();
number().finite();
number().infinite();
number().enumerated([1, 2, 3]);
number().exact(5);To perform simple transformations:
dart
number().pow(2);Booleans
Use the boolean() method to create a boolean schema. This method allows you to validate and transform booleans.
dart
boolean().isTrue();
boolean().isFalse();Dates
Use the date() method to create a date schema. This method allows you to validate and transform dates.
dart
date().min(DateTime.now());
date().max(DateTime.now());
date().differsFromNow(Duration(days: 5));
date().differsFrom(DateTime.now(), Duration(days: 5));
