eskema function

IEskValidator eskema(Map<String, IEskValidator> eskema)

/////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////// Returns a Validator that checks a value against a Map eskema that declares a validator for each key.

Example:

final mapField = all([
  eskema({
    'name': all([isType<String>()]),
    'vat': or(
      isTypeNull(),
      isGte(0),
    ),
    'age': all([
      isType<int>(),
      isGte(0),
    ]),
  }),
]);
