Constructors

EasyValidator([String? errorMessage])

const

EasyValidator.compose(List<EasyValidator> validators)

Composes multiple validators into a single validator.

const

factory

EasyValidator.contains(String contains, {bool caseSensitive, String? errorMessage})

A factory constructor for creating a ContainsValidator. The contains parameter specifies the string that the value being validated should contain. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.containsNumbers({RegExp? regExp, String? errorMessage})

A factory constructor for creating a ContainsNumbersValidator. The containsNumbers parameter specifies the string that the value being validated should contain. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.custom(ValidatorCallback<String> validator)

A factory constructor for creating a custom validator.

const

factory

EasyValidator.email([String? errorMessage])

Creates an instance of EmailValidator with the provided errorMessage.

const

factory

EasyValidator.endWith(String endWith, {bool caseSensitive, bool useTrim, String? errorMessage})

A factory constructor for creating an EndWithValidator. The endWith parameter specifies the string that the value being validated should end with. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.equalLength(int length, [String? errorMessage])

A factory constructor for creating an EqualLengthValidator.

const

factory

EasyValidator.equalTo(String equalTo, {bool caseSensitive, bool useTrim, String? errorMessage})

A factory constructor for creating an EqualToValidator. The equalTo parameter specifies the string that the value being validated should be equal to. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.maxLength(int maxLength, [String? errorMessage])

A factory constructor for creating a MaxLengthValidator.

const

factory

EasyValidator.maxWordCount(int maxWordCount, [String? errorMessage])

A factory constructor for creating a MaxWordCountValidator. The maxWordCount parameter specifies the maximum number of words that the value being validated should have. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.minLength(int minLength, [String? errorMessage])

A factory constructor for creating a MinLengthValidator.

const

factory

EasyValidator.minWordCount(int minWordCount, [String? errorMessage])

A factory constructor for creating a MinWordCountValidator. The minWordCount parameter specifies the minimum number of words that the value being validated should have. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.notContains(String notContains, {bool caseSensitive, String? errorMessage})

A factory constructor for creating a NotContainsValidator. The notContains parameter specifies the string that the value being validated should not contain. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.notEndWith(String notEndWith, {bool caseSensitive, bool useTrim, String? errorMessage})

A factory constructor for creating a NotEndWithValidator. The notEndWith parameter specifies the string that the value being validated should not end with. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.notEqualLength(int length, [String? errorMessage])

A factory constructor for creating a NotEqualLengthValidator. The length parameter specifies the length that the value being validated should not have. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.notEqualTo(String notEqualTo, {bool caseSensitive, bool useTrim, String? errorMessage})

A factory constructor for creating a NotEqualToValidator. The notEqualTo parameter specifies the string that the value being validated should not be equal to. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.notStartWith(String notStartWith, {bool caseSensitive, bool useTrim, String? errorMessage})

A factory constructor for creating a NotStartWithValidator. The notStartWith parameter specifies the string that the value being validated should not start with. The errorMessage parameter is an optional error message to be displayed if the validation fails. Example usage:

const

factory

EasyValidator.regExp(RegExp regExp, [String? errorMessage])
