FormValidationMode enum
Defines when form field validation should occur during the component lifecycle.
This enumeration controls the timing of validation execution, allowing fine-grained control over when validation logic runs. Different validation modes can be used to optimize user experience and performance.
Values
- initial → const FormValidationMode
-
Validation occurs when the field is first created or initialized.
This mode runs validation immediately when a form field is created, which can be useful for fields with default values that need immediate validation feedback.
- changed → const FormValidationMode
-
Validation occurs when the field value changes.
This is the most common validation mode, providing immediate feedback as users interact with form fields. Validation runs after each value change event.
- submitted → const FormValidationMode
-
Validation occurs when the form is submitted.
This mode defers validation until form submission, reducing interruptions during user input. Useful for complex validations that should only run when the user attempts to submit the form.
