In this episode, we’ll build a clean and reusable AppValidator class to organize your validation logic. You’ll learn how to:
Create centralized validator methods (e.g., email, password, name validation)
Use regular expressions (regex) for pattern-based validation
Keep your TextFormField usages clean by referencing shared validators
Improve maintainability and consistency across your forms
By the end, your forms will not only work better—they’ll be easier to manage and reuse.
