In a situation where you need to validate multiple fields in a Flutter form at once, which approach is most effective?
- Implementing a separate Validator class for each field
- Leveraging the Form widget's onFormSubmission with a centralized validation logic
- Using a custom validation function for each field
- Utilizing the Form widget's onChanged callback with a validator function
The most effective approach to validate multiple fields in a Flutter form at once is by leveraging the Form widget's onFormSubmission callback with a centralized validation logic. This allows you to perform comprehensive validation across all fields when the form is submitted. By handling validation at the form level, you can coordinate the validation logic, provide a cohesive user experience, and efficiently manage the validation process for all fields in a centralized manner.
