Steps validation in Angular Stepper component

27 Apr 20244 minutes to read
The Stepper component allows you to set the validation state for each step, displaying either a success or error icon. You can define the success state of a step by setting the isValid property to true. If set to false, the step will display an error state. By default, the isValid property is null.
Based on the stepType, the validation state icon will be displayed either as an indicator or as part of the step label/text.
