validationMessage property

String get validationMessage

Returns the error message that would be displayed if the user submits the form, or an empty string if no error message. It also triggers the standard error message, such as "this is a required field". The result is that the user sees validation messages without actually submitting.

Implementation

_i2.String get validationMessage => _i4.getProperty(
      this,
      'validationMessage',
    );
