Boolean

A boolean validator is used to validate a boolean value.

Example

import 'package:acanthis/acanthis.dart';

void main() {
  final result = boolean().tryParse(true);

  if (result.success) {
	print('The schema is valid!');
  } else {
	print('The schema is invalid!');
  }
}

TIP

The AcanthisParseResult object, that is returned by the parse and tryParse method is described here.

Methods

isTrue

The isTrue method is used to validate that a boolean is true.

import 'package:acanthis/acanthis.dart';

void main() {
  final result = boolean().isTrue().tryParse(true);

  if (result.success) {
	print('The schema is valid!');
  } else {
	print('The schema is invalid!');
  }
}

isFalse

The isFalse method is used to validate that a boolean is false.

import 'package:acanthis/acanthis.dart';

void main() {
  final result = boolean().isFalse().tryParse(false);

  if (result.success) {
	print('The schema is valid!');
  } else {
	print('The schema is invalid!');
  }
}
